Software update

GNU GPLv2 Licenced

The code that makes Rockstor possible is developed under the GNU GPLv2 licence and is therefore fully Open Source, there is no contributor agreement and everyone is encouraged to help in what ever way they can. It is very much developed in the open with key decisions made by the community and their interaction with Rockstor contributors and maintainers Our Mission. This flow of ideas and open development is held as a founding principal and is instantiated in the Rockstor forum and within the code itself on GitHub.

Rockstor the project embodies an identifiable software distributor and coordinator of the Open Source product that is the scheduled Rockstor releases. It also forms an identifiable entity necessary for the support of the releases (where needed) and infrastructure necessary to maintain the open development that is essential in modern non trivial software appliances that have any hope of qualifying as future-proof.

After an initial development of 2.5 years the sustainable nature of this endeavour was approached and redressed in a thread on the community forum. The consensus was to adopt a two-tiered updates model; testing and stable.


The update alternatives offered in Rockstor.

Testing Channel

The testing channel for updates is intended primarily for developers or for those who wish to actively test Rockstor and who are entirely happy on the developmental edge of releases. There is growing unit test coverage that all releases are expected to pass prior to their release, but, given the rapid nature of these releases weekly or shorter, it is not recommended to put production systems on this update channel. The flip side is that a rapid release cycle affords fast development and widespread field testing of what ultimately becomes the Stable Channel at curated points.

However, it must be understood that appliance development is a complicated business and it is inevitable that along the way fixing one thing will break another. All reasonable efforts will be made to avoid obvious breakage. But ultimately this testing channel is intended to find problems by way of tester/developer reports and collaboration and will involve partially implemented features of an experiment nature. The intention is to provide a feature testing platform that we can gradually stabilise before then releasing it’s stable channel spin offs at known good points.

Participation in the testing channel along with considered bug, code, or documentation contributions is the heart of Rockstor development and along with patience and understanding can only benefit all those involved. Please see additional benefits.

N.B. due to recent resource shortages we have had to temporarily suspend the testing channel in favour of serving our Stable channel subscribers. But all efforts are under way to re-establish this valuable and previously popular development facility. Our pending and long planned move to openSUSE is intended to mark the re-birth of this developer favoured channel.

No charge


There is really no better testing alternative than thousands of willing testers putting a proposed product to uses that were never envisaged by its developers; and when those testers/developers see rapid iteration in the problems they find/fix and report, everybody wins. It’s the classic Bazaar model described in CatB.

Stable Channel

This is the recommended channel for Production Rockstor use. The frequency of releases is much lower (monthy or longer) than those in the Testing Channel and there is the reassurance that updates in the stable channel have been field tested first in the testing channel. This channel will receive the highest attention with regard to bug fixes, whereas the testing channel is more focused on development rather than refinement. There will also be greater attention paid to avoiding regressions from one stable channel release to the next.

Below we see the process involved in setting up the stable channel updates. A link is provided to the Rockstor shop showing the Stable Updates subscription option. On selection and purchase the activation code will be emailed to the address given. This code is intended for the dialog shown below. Also note our Testing Email section where the Appliance ID, a UUID generated during install, is contained within the test email. The appliance ID is used to identify an individual install and when paired with an activation code configures stable channel access.

N.B. When re-installing on a different motherboard, or where the boards product_uuid is non unique, a different appliance id will result. This means the prior installs activation code will no longer work against the new appliance id. For this circumstance we have our in public beta test Appliance ID manager (appman). Please be patient as we work our the teething problems expected with newly release systems. Specific documentation will follow once we have established the less self explanatory elements.

Participation in the stable channel is key to the future of Rockstor development. The ability to continue to improve and provide future-proof services, by way of advanced file system facilities made easy, is dependant on a financial component. The stable channel is that financial component. Currently a one-year subscription costs £20.00 (GBP).

Please keep an eye on our friendly forum as discount / promotional codes are occasionally issued.

Yearly subscription managed by appman


Rockstor project repositories: contributors qualify for up to 10 personal use activation codes.

Auto Updates

When enabled, auto update checks for all system updates and installs them automatically on a daily basis. This is the recommended setting when on the Stable Channel only. If you are on the Testing Channel it is not recommended to enable auto updates but instead to evaluate all updates prior to applying them; this advice is down to the more unstable nature of the testing channel and its inevitably greater chance of breakage or bugs.


N.B. Auto updates are only recommended when on the stable updates channel
