3.8-10: Asynchronous Replication plus many improvements

Rockstor 3.8-10 release is now available. This is our second release in the Stable updates channel. Many thanks to users who purchased Stable update subscriptions. Your support is not only greatly appreciated, but crucial to us. If you are subscribed to Stable updates, you can easily update the system from the Web-UI.

New users can download 3.8-10 from here. Keep Rockstor live and thriving by purchasing the Stable subscription!

We closed 13 issues in this release, compared to 20 in 3.8-9. And this release took a bit longer. If you are wondering why, it’s because of the big feature improvement in this release: Asynchronous Replication. This feature efficiently replicates Shares on one Rockstor appliance to another by using BTRFS send/receive functionality. While this feature was added a while ago, it was a bit over engineered, buggy and had to be improved. I started refactoring the existing pub-sub design and ended up completely redesigning it. The result is a much simpler and more robust implementation. I plan to write more about it here and the community wiki soon.

Besides Replication, the community really came together to help fix a bunch of bugs, make several enhancements and also improve test coverage. I want to thank our regular contributors @phillxnet, @Mchakravartula, @priyaganti for their important pull requests, testing and insights. Plus, special thanks to @grogi, our new and 11th contributor! Last but not least, the community involvement has been superb with testing, bug reports and knowledge sharing. It’s very encouraging to have such a smart and diverse feedback system as we continue to improve Rockstor.

Here’s the list of issues resolved in this update with links to more information.

3.8-9: AD integration, S.M.A.R.T and other improvements

Rockstor 3.8-9 update is now available. This is our first update released under the stable update channel. Some of you may be aware that we split updates into Stable and Testing channels. I wrote about this briefly in the last post and there’s more information about them in our documentation as well.

Current users running prior versions can update to 3.8-9 after activating the Stable channel subscription. New users can just install from the 3.8-9 ISO. Since the launch of update subscriptions a few weeks ago, we are seeing steady purchases. I am happy to see organic traction, but we need a lot more subscriptions to keep up the effort. So, if you like Rockstor and haven’t bought the Stable subscription yet, please do!

We closed 20 issues in this release and I want to thank all the contributors. We have a dev log in our forum detailing the ongoing work and some of you may already be aware of the coming changes. Detailed list follows, but the highlights include fixes to Active Directory integration, S.M.A.R.T monitoring, better Systemd integration and improved test coverage.

I want to thank @phillxnet for contributing many minor enhancements, @Mchakravartula for improving test coverage and fixing up code along the way, @maxhq for being our new and 10th contributor(hooray!) and @roweryan for testing, reporting issues and ensuring that we aren’t slacking ūüôā Last but not least, many thanks to @vinima for contributions to documentation and video tutorials.

3.8-8: UPS support, shadow copies and more

Rockstor 3.8-8 update is now available. This update cycle ended up a bit longer(about 4 weeks) compared to our average of 2 weeks. There are two reasons for this. (1) We closed more issues than usual and (2) We are focusing more on stability.

Going forward, we are splitting updates into two channels. For those of us that actively want to test cutting edge updates, there is now a Testing updates channel. Once we test in the dev environment and run automated tests, we’ll release an update on this channel. So an update is released roughly for each pull request, perhaps once every other day or so.

The second is the Stable updates channel. This is a slight variation of what we’ve been doing all along. But given that installs have gone up quite a bit, we’ll focus on stability and do a lot more testing to minimize risk of regressions. As a result, updates will be released at a slightly slower pace, like once in 3-4 weeks on the Stable update channel. I plan to share more details about these channels in a separate post.

Back to this update, which has many useful changes. First, support for UPS is added. I am personally looking forward to using this feature on production Rockstor systems here that serve the Forum, CI, updates etc.. Second, support for Shadow copies for Windows Samba clients is added. We plan to add more documentation and write up how-to posts about these features. Documentation for UPS has just been added, thanks to @phillxnet. Last but not least, we’ve improved the overall functional test coverage and brushed up the UI.

On the BTRFS side of things, We’ve been testing 4.2 kernels since their release and 4.2.2 is working fine in all of our machines here and we were able to test all supported BTRFS functionality. So, we’ve made 4.2.2 the default with this update. Just as important, the wonderful btrfs-progs is also updated to 4.2.1. Do note that qgroups(share sizing), replication and DR(for raid5/6) features are yet to be re-tested for improvements, so no changes to report as of now.

Here is the list of all issues resolved in this update.

1. Added support for UPS. #595 @phillxnet

2. Added Shadow Copy support for Windows Samba clients. #715 @schakrava @priyaganti

3. Improved Network management #799 @schakrava

4. Improved User management functional test coverage #856 @Mchakravartula

5. Improved NFS functional test coverage #876 @Mchakravartula @schakrava

6. Improved AFP functional test coverage #877 @Mchakravartula

7. Improved SFTP functional test coverage #878 @Mchakravartula

8. Made development side of supervisor processes consistent with production. #852 @phillxnet

9. Improved UI for mobile #869 @snamstorm

10. Made forms on the UI better and consistent. #891 @priyaganti

11. Added Stable and Testing updates channels. #899 @schakrava @priyaganti

3.8-7 UI enhancements and misc improvements

Rockstor 3.8-7 update is now available. Once again we are happy to push an update quicker than usual, for two additional reasons besides the obvious reason that more than average number of issues were closed already. One, there have been so many improvements since 3.8-0 ISO was baked and it’s time to create a new one. We were going to do that with 3.8-6, but a minor issue came up during testing which has since been fixed. Two, @snamstorm made really cool UI improvements which I can’t wait for users to see. It’s still an ongoing effort and I am looking forward to future changes. So, stay tuned.

If you are doing a fresh install, please download the new ISO file from here.

Here’s the list of issues resolved.

1. Added more functional tests. #828 @Mchakravartula

2. Improved styling of the login page. #815 @snamstorm

3. Made ssh access stricter and fixed a sftp related bug. #838 @schakrava

4. Improved display of contributions during update #845 @priyaganti

5. Improved top menu bar in the UI #832 @snamstorm

6. Added support to use system timezone #712 @schakrava

7. Improved sidebar menu in the UI #840 @snamstorm

8. Cleaned up Share detail page in the UI #814 @Mchakravartula

9. Add quota support for imported pools and shares. #687 @schakrava

Creating a Rockstor USB install drive on your Mac

In this tutorial, we are going to show you how to create a Rockstor USB install drive on your Mac. You can then use it to install Rockstor on a computer system of your choice. As you might have noticed, Rockstor runs a variety of hardware such as the Intel Nuc or ASUS VivoPC. Anyways, lets get started! Firstly, instead of following this tutorial to create a USB installer drive of your own, you can buy one from the Rockstor shop and support our efforts. Secondly, make sure you are on a Mac, because this is a tutorial for Mac.

Make sure you have downloaded the Rockstor ISO – it can be downloaded from here. In this tutorial, I will save the ISO under downloads but you are free to save it anywhere on your Mac. My only advice is that you try not to save it on a high-level folder since you will need to access the root through the command line.

 

USBMountMac-07

While the ISO is downloading, we can get started on formatting the USB stick. Insert it and check that it is being read by your Mac. You can do this by opening the Finder and looking at the left panel under devices.

USBMountMac-11

Make sure your USB is erased and journaled. This is to make sure that nothing that was previously on your USB interferes with your Rockstor installation. You can do this easily through the Disk Utilities that come with Mac.

This can be found under:
– Finder > Applications > Utilities > Disk Utilities

USBMountMac-08

Select your USB Drive from the side panel. Make sure to select the right drive as all data will be wiped from the drive you select to erase. Once you have selected the USB Drive,
– Click on Partition
– Select 1 Partition from The Partition layout drop down menu.
– Click Apply

This will erase everything from your USB.

USBMountMac-06

There are many articles on the web showing how to mount OS X onto a USB drive using disk utility. This does not work, you will end up getting an error ‚ÄúCould not validate source ‚Äď Invalid argument‚ÄĚ because Apple has pretty much built this feature to only comply with their software – as they always do. Thankfully, this tutorial will help you get around this quite easily.

USBMountMac-03

Open your Mac Terminal. You can find this in your applications by opening
– Finder > Applications > Disk Utilities > Terminal

USBMountMac-09

In your terminal, type:
> diskutil list
This comes standard with Mac. A list of all disks accessible by your mac will show up. Look for your USB drive. A key indicator is the size РIn this example, my USB is 16GB so it would be disk 2

USBMountMac-10

Make sure your disk is unmounted. Type:
> 
diskutil unmountDisk /dev/<Your Disk #>
Make sure you get a success message.

USBMountMac-12

Next step is to copy over the ISO you downloaded to the USB (Download the ISO here). We use ‚Äėrdisk‚Äô instead of disk because it is faster Type:
> 
sudo dd if=/Users/Nam-Storm/Downloads/Downloads/Rockstor-3.8-0.iso of=/dev/rdisk2
Entering the sudo command will require your admin password (due to the sudo ‚Äď Super User do command). It will then take some time to copy your data and you won‚Äôt get any feedback from the terminal.

USBMountMac-04

If you are unsure of the location path to the ISO then you can cd into the folder you saved the file and do a pwd.
> cd Downloads/Downloads/
> ls
> pwd

 

USBMountMac-02

Finally, you should get a message of the transfer that has taken place. This can take up to 20 minutes.

USBMountMac-01

You can now check your USB to make sure the Rockstor is loaded on
That‚Äôs it ‚Äď you now have a mounted USB and can use it to install your very own Rockstor.

3.8-6 update. enhancements and bug fixes!

Rockstor 3.8-6 update is now available. This one is packed with enhancements and bug fixes. And so many of them just in 10 days since the last update. There are no major features added, but all of the improvements together made Rockstor stable and polished. We’ve also tested it quite a bit, thanks to our talented community members. Linus has decided to give it a bit more testing before releasing 4.2 kernel(predicted next week), so we are looking forward to rolling it out within next two updates after some thorough testing.

There is no single highlight issue in this update, but I am pleased by the total number of issues resolved. On average, 3-5 issues are closed in a update cycle of about 2 weeks. But for this one, we closed 12 issues in 10 days. How did we do it? Community! From testing to R&D to pull requests, it’s been busy 10 days of great contributions and a rapidly improved software.

Here’s the list of issues resolved.

1. Enhanced the auto software update process. #695 @schakrava

2. Improved disk serial number identification logic. #757 @phillxnet

3. Added support for Rock-on installation using Firefox browser. #744 @priyaganti

4. Made Rock-on service state persistent after reboot. #721 @schakrava @phillxnet

5. Fixed buggy NFS export management. #713 @schakrava

6. Improved functional test coverage #733 @Mchakravartula

7. Fixed S.M.A.R.T service configuration management. #741 @schakrava @phillxnet

8. Fixed NTP service for it’s state to be persistent after reboot. #768 @schakrava

9. Improved e-mail notification setup. #793 @phillxnet

10. Improved wording. #792 @phillxnet

11. Fixed a minor UI bug to refresh properly after a disk wipe. #635 @schakrava

12. Improved tooltips #802 @priyaganti

3.8-5 update. bug fixes, performance and UI enhancements!

Rockstor 3.8-5 update is now available. I am very pleased with all the work that went into this update. Over all, we’ve added a couple of new features, but mostly focused on fixing several bugs and enhancing performance and user experience. This pattern of focusing on reliability and stability will continue for next few updates. With Linux 4.2 kernel around the corner, I am looking forward to improvements in BTRFS.

The highlight of this update for me, personally, is the new reworked data-collector service which improves performance and user experience. On the server side, we’ve eliminated all unnecessary I/O for stats collection, and using Gevents and SocketIO, decreased the compute and memory footprint. On the frontend, all polling for the dashboard is eliminated, making the UI a lot smoother and consume a lot less resources. We accomplished this improvement by removing more code than we added, so that’s a bonus!

We add support for setting up e-mail notifications. Users can configure to use an e-mail account they own, like a gmail or zoho account and Rockstor uses the supplied credentials to send e-mail notifications to your preferred e-mail address. All root e-mail, for example, is forwarded by default and other services like SMARTD that can send e-mail notifications and take advantage of this setup.

Finally, most of the work for this update was around bug fixes and enhancements. After this update, users will notice UI to be smoother and more responsive. We’ve also closed subtle server side bugs. Many thanks to our community members for their valuable time and contributions in helping us fix these issues faster. Below is a more detailed account of the work, issue by issue.

1. Reworked the data-collector service and removed dashboard polling. Both server and client side performance is significantly improved and all unnecessary IO is eliminated. #763 @gkadillak @schakrava

2. Fixed buggy behavior with display and deletion of Clones. #727 @schakrava

3. Added support for e-mail setup for receiving notifications and alerts. #633 @Mchakravartula @schakrava

4. Fixed broken UI during Share rollback. #774 @schakrava

5. Fixed Samba export field display on edit. #767 @Mchakravartula

6. Added support to set Samba workgroup from the UI. #678 @schakrava

7. Enhanced Share ownership edit form to display sorted users and correct pre-select values. #775 @Mchakravartula

8. Reworked Pool resize logic to be simpler and more robust. #580 @schakrava

As always, update your Rockstor installation via web-ui. If you are new to Rockstor, watch the short video that demonstrates this process.

Backup your iPhone with BTSync and Rockstor

I’ve been looking for an alternative to back up my¬†iPhone 5S 16GB (iOS 8.4) in order to free up space to upgrade to iOS 8.4.1 that wouldn’t install as it needs 691MB of additional storage. ¬†The biggest storage suck on my phone is the ‘Photos and Camera’ folder (7.1 GB). The alternatives for additional storage are to upgrade my iPhone, delete unwanted pictures and videos, or put data onto the iCloud. A quick search revealed¬†some other options¬†but none of these alternatives seem appealing, because :

1) My iPhone is in perfect working condition

2) Deleting unwanted data and videos is too much of a hassle

3) Backing up the iPhone to Google Drive or Dropbox or an external hard-drive is not an option as I have a Rockstor powered NAS box at home

4) Backing up to a computer (Macbook for me) is not attractive either, as I prefer my photos sync to backup daily

5) Buying more storage on iCloud is its own beast.  It involves recurring payments (that I despise as these appear innocuous upfront but then sneakily add-up).  Take a look at the monthly iCloud plans in the US.

iCloud plan cost (per month) in United States (USD)

20 GB: $0.99

200 GB: $3.99

500 GB: $9.99 

1 TB: $19.99

(Source : https://support.apple.com/en-us/HT201238)              

Even though it does not apply to my use-case, it is worth noticing if there are 4 users in a household, it would cost approximately $48 a year (assuming $0.99, 20GB plan per year for each of the users), and if you are a small business and you and your employees need to share photos on iCloud, it comes with its own restrictions and limit. Click here to know these restrictions.

6.  Another reason to not upgrade to iCloud or Google Drive or Dropbox is privacy.  While it is not important to me at this point, as my Camera folder contains everyday photos, but could matter to certain users.  Apple manages encryption and there have been news about recent iCloud hacks into celebrity photos and articles about hacking into iCloud.

So, it was time to look for another solution and I found the solution right up my alley – a Rockstor powered box with Bittorrent Sync Rock-on. ¬†In this blog, I describe the process of setting up backup for your iPhone. ¬†(Note : I’ve used free version of BTSync 2.0 for this use-case. When you first install BTSync rock-on, the trial version of BTSync Pro is automatically turned on. I am still under free-trial, but will test the behavior once the trial period expires. I understand that there are restrictions like, folder limit to 10, that apply to free version and BTSync Pro is pretty expensive, $39.99 per year, per device, so it would cost $79.98 to use Rockstor + BTync + iOS for backup, and iCloud plan up to 200GB is cheaper compared to BTSync 2.0 Pro.).

First step was to download and install Sync app on my iPhone (search for ‘BTSync’ in App Store). ¬†The app looks something like this :

IMG_2752

Once the Sync app was installed on my iPhone, the next was to start configure the Rockstor box and start BTSync Rock-on and then sync iPhone to Rockstor box using BTSync.

1. I am assuming your Rockstor box is already setup. If you are new to Rockstor, read the Quick start guide. I created a 100GB share called ‘vinima_iphone_backup’ in the ‘rockstor_rockstor’ pool.

2. Installing the BTSync Rock-on is pretty simple. Just follow the install wizard with defaults as documented here with screenshots. After the initial Rockstor settings, its time to start the BTSync service.

Screen Shot 2015-08-02 at 3.01.14 PM (1)

 

3. ¬†Now, it’s time to configure the BTSync Rock-on. ¬†In BTSync Install Wizard, choose “vinima_iphone_backup” for Data Storage. ¬†This folder (share) was created created in step 1.

Screen Shot 2015-08-14 at 10.39.29 AMScreen Shot 2015-08-14 at 10.39.16 AM

 

4. ¬†This share shows under ‘Resource Type’ under BTSync Install Wizard. ¬†Click ‘Next’ and then click ‘Submit’ to finish installation.

Screen Shot 2015-08-14 at 10.39.40 AM    Screen Shot 2015-08-14 at 10.39.58 AM

5.  Proceed to start the BTSync service on Web-UI.

Screen Shot 2015-08-02 at 3.06.50 PM (1)             Screen Shot 2015-08-02 at 3.07.26 PM

6. ¬†I tried to link iPhone to Rockstor backup by scanning the¬†QR code on iPhone and manually (by copying the key) to ‘ BT Sync’ app on my iPhone. ¬†You may need to scan either the QR code or enter the key manually. ¬†For some reason, scanning QR code didn’t link the iPhone and Rockstor backup for me, so I copied the key. Once the code is accepted, BTSync Rock-on detects the ‘Sync’ App on my iPhone. ¬†I pointed to “vinima_iphone_backup” share.

Screen Shot 2015-08-14 at 10.55.54 AM          Screen Shot 2015-08-14 at 11.08.57 AM

7. ¬†Once the iPhone and Rockstor box are synced, you can see the file transfer. ¬†You can look under ‘History’ in Web UI to see the individual files uploaded. ¬† After syncing, a random name ‘8079baf89ba’ was assigned to the BTSync rock-on on Rockstor box. ¬†I changed this random name to ‘BTSync-Rockstor’ under “Preferences” in the BTSync Web UI.

 

Screen Shot 2015-08-14 at 11.20.37 AM     Screen Shot 2015-08-14 at 11.33.07 AM

7. ¬†This is how things look on my iPhone. ¬†BTSync app identifies the BTSync service on Rockstor box and starts backing up my files from my camera.¬† According to BTSync help¬†you can only backup your iPhone camera roll, which was actually consuming most of cloud storage for my use-case, but yes, it may not work if you have music or other data on your iPhone that you want to backup. ¬†Quoting from BTSync documentation ¬†“While Android can back up data from virtually any location the device can reach, iOS applications cannot read files outside the application folder. So the iOS version of Sync can only back up Camera Roll as it is can be accessed by any application if user grants permissions to do it”)¬†

 IMG_2746 IMG_2749  IMG_2761IMG_2760

8. ¬†Once the file transfer starts, go to the command line, to check the status of file transfer. ¬†The status of transfer-in-progress and completed transfer are shown below. ¬†You can also check the status by clicking “History” on the BTSync WebUI.

Screen Shot 2015-08-02 at 3.16.37 PM          Screen Shot 2015-08-02 at 3.17.46 PM

According to the BTSync¬†help documentation, have the backup option always turned on¬†“When backup is enabled, even if you delete the backed up files from your mobile device, their copies will remain intact on the computer you‚Äôve backed them up to.” The initial set-up for backup was done within my home network. ¬†It is a good idea to have your phone fully charged as syncing drains out the battery fast. ¬†I was able to sync my phone outside of the home network when I was connected to Wi-Fi. Synching outside the home network happens due to a protocol called uPnP (Universal Plug and Play) which works pretty well with the Sync app.

My next step will be to empty the “Photos and Camera” folder. ¬†My next blog will discuss that process in addition to the behavior of BTSync beyond the trial period. ¬†Also, I will be investigating the possibility of seeing thumbnails of backed up images.

3.8-4 update. config backup-restore and bug fixes

Rockstor 3.8-4 update is now available. This is mostly a bug fix release barring one new feature, a major one that some of our users have been waiting for. We are getting great community feedback lately which is helping us hunt bugs down and fix them. So for next few updates, the focus will primarily be on bug fixes to make Rockstor more and more reliable. We may still add small features and enhancements, but bug fixing will be the priority. Given that both Rockstor and BTRFS are cutting edge, we may be a few releases away before calming down. It’s getting close!

The new feature in this update let’s you take a config backup of the system and restore it later. This is meant to be useful after rebuilding a Rockstor system after a root drive crash. Users, groups, NFS/Samba/AFP exports and service configurations can be restored easily.

As with the last update, we’ve also fixed a bunch of bugs, thanks to our community We are prioritizing all serious bugs reported for future updates. All critical bugs are listed here. Every bug in this list is treated with high priority.

This is the detailed list of changes in this update:

1. Added support for config(system state like users, exports etc..) backup and restoration. #392 @schakrava @gkadillak

2. Fixed task scheduling. #728 @gkadillak @schakrava

3. Fixed units drop down in Share resize form #745 @Mchakravartula

4. Fixed advanced nfs exports feature #754 @schakrava

5. Fixed wrong kernel warning message #746 @gkadillak

6. Fixed scrub status parsing #752 @schakrava

As always, update your Rockstor installation via web-ui. If you are new to Rockstor, watch the short video that demonstrates this process.

SSD boot drive for DIY Rockstor systems

Being engineers, we really like the DIY approach here at Rockstor. We have systems put together using components from old desktop servers running Rockstor in our various environments. Judging by the number of inquires we get via e-mail and our forum, there are many users out there building DIY NAS systems with Rockstor. The most frequently asked question is if Rockstor can boot from something like a USB drive. By doing so, all of the HDDs on the system can be exclusively allocated for data.

Whiles it’s possible to run Rockstor from a USB drive, we recommend a much faster solution while freeing up all your HDDs for data. All that’s required of your motherboard is a PCI-Express slot to house a mSATA III + SSD boot drive. We’ve been running this setup for a while on some of our systems and so are some others in the community. So we decided to offer it in our shop.

PCI-Express(x1) mSATA III (6G) boot drive (16/32 GB)

It’s available in both 16GB and 32GB capacities which is plenty considering it doesn’t take more than a few GB to run Rockstor. Here are some feature highlights of this boot drive.

  • Provides extra SATA III port for additional storage devices (hot-pluggable)
  • 14K random 4KB read IOPs
  • 19K random 4KB write IOPs
  • TRIM and SMART support

The card meets PCI express specification rev 2.0 and plugs into an x1, x2, x4, x8 or x16 slot, one of which can be found on pretty much any motherboard. Besides running a pretty fast Rockstor system with this boot drive, you’ll be supporting our effort and make it easier for us to support you by running Rockstor on familiar hardware. So head on over to our shop and get one today!
