Since no issues were reported for the last release candidate, this final release contains no additional changes.

Whats new?

With this release, we changed the way the controller works completely. Previous versions would only communicate with the LINSTOR Controller to watch for resource events. This new version uses the DRBD state on every node directly. This also means that the workload changed from a simple deployment to a daemonset.

To give it a try, use the newly created chart in this repository. On full release, it will move to our main chart directory.

helm install --create-namespace --namespace piraeus-ha-controller piraeus-ha-controller charts/piraeus-ha-controller

The new HA Controller is also better equipped to deal with "suspended" resources. Suspended resources fix a frequently encountered problem where DRBD would report errors to consuming pods during network issues. This would often lead to the filesystem silently remounting as readonly. Using these new recommended storage class settings, DRBD instead freezes the Pod until it is terminated or networking restored:

parameters:
  property.linstor.csi.linbit.com/DrbdOptions/auto-quorum: suspend-io
  property.linstor.csi.linbit.com/DrbdOptions/Resource/on-no-data-accessible: suspend-io
  property.linstor.csi.linbit.com/DrbdOptions/Resource/on-suspended-primary-outdated: force-secondary
  property.linstor.csi.linbit.com/DrbdOptions/Net/rr-conflict: retry-connect
