Network File System (NFS)

Export Shares via NFS

Rockstor uses Linux NFS server to support exporting Shares to remote clients via NFS. Both NFS v3 and v4 are supported. UID and GID mapping for the exported shares can be handled by manually creating users or by using directory services like LDAP, NIS or AD.

To manage NFS exports, click on NFS under the Storage tab in the Web-UI. If there are any exports in the system, they are displayed in a table. If there are large number of exports, the table is paginated and the current page number is displayed below the table along with Prev and Next buttons.

The display can be sorted by individual columns by clicking small up/down arrows displayed in each column header.


Below are the main operations possible from the NFS view, which operate on one or more shares and is a convenient way to manage exports for the entire system. Rockstor also makes NFS export management possible for a specific share from within the NFS tab of a share’s detail view.
