linstor-server 1.31.0-rc.1 release

Release Announcements

Hi!

Here is the first release candidate for the upcoming 1.31.0 minor release,
as you will see below this release has a huge amount of changes, why we will have at least a 2 week RC phase and maybe an additional RC release.

Some highlights of this release:

  • Fixed snapshot rollback
    Snapshot rollback only worked if the resource/node the snapshot was made, did never
    get deleted or moved to another node. As the new node would never have the origin
    snapshot. We came up with a node resync idea and for ZFS with a renaming and refcounting
    method to make sure snapshot rollback always works.
  • Auto-quorum reworked
    The auto-quorum property was very special and hard to understand as it didn’t follow
    the Linstor principle of inheriting properties. It usually copied its value into the on-no-quorum
    property and you had to change each of them, if you wanted to update all of them.
    Now the property is gone and the behaviour will only be controlled by the DRBD option
    quorum.

[1.31.0-rc.1] - 2025-03-19

Added

  • Notify controller about replication state changes in DRBD
  • Notify controller about done percentage changes in DRBD
  • Encryption-API: added a GET endpoint to ask for the master passphrase status

Changed

  • BalanceResource: Ignore resources which are in a non-valid replication state
  • sos-report: include backup ship queue
  • sos-report: syslog will only be gathered if messages was not available
  • Clone: check that a resource name for the cloned resource is set
  • Clone: fail clone if the source resource isn’t UpToDate or has skip-disk
  • Memory: Limit satellite to 2G max memory (-Xmx2G) and controller to 8G
  • JVM: will now crash on OutOfMemoryError
  • Limit reactor worker threads to 16
  • DRBD .res file now contains the time the file was generated
  • BalanceResource: Improved selection when deleting excess resource
  • AutoDiskfulTask: Improved selection when deleting excess resource
  • Tiebreaker: Improved decision making if a deleting resource should be kept as tiebreaker
  • Write a full documented linstor.toml and remove the linstor.toml-example
  • Snapshot rollback now does internally a resource delete + snapshot restore
  • ZFS resource can now be deleted while having ZFS snapshots (ZFS volumes will be renamed)
  • ZFS snapshots can now be deleted while having ZFS clones (ZFS snapshots will be renamed)
  • Auto-quorum: Reworked auto-quorum property behaviour, property was removed and auto-quorum is now managed through
    the drbd option quorum. on-no-quorum properties will be inherited.
  • BackupShip: start next queued shipment immediately when sending fails

Fixed

  • Reconnect: Fixed rare race condition in DRBD version check
  • Resource delete: Fixed rare race condition where a delayed DRBD event causes “resource not found” ErrorReports
  • Fixed possible UUID mismatch after deletion of last snapshot failed to properly clean up satellite
  • Fixed “resource not found” bug when restoring from a snapshot when the source-resource was already deleted
  • Satellite: Fixed rare “attempt to replace active transMgr” error
  • SATELLITES_CAPACITY table NODE_NAME size was too short
  • BackupShip: queued backups are now removed if the target cluster goes offline
  • BackupShip: do not use snapshots that are deleting as base for an incremental backup
  • BackupShip: remove snapshots from queued backups that have them as base when deleting them
