Is your improvement request related to a feature? Please describe (👍 if you like this request)

SPDK volumes support per-volume automatic replica rebuilding, so UI needs some updates

• Can specify Volume.Spec.OfflineReplicaRebuilding when creating a volume. The values are

  • ignored (default value)
  • disabled
  • enabled

• Volume page can change volume.Spec.OfflineReplicaRebuilding

• If a SPDK volume is degraded, should a warning message remaindering users that replica rebuilding will be automatically triggered when the degraded volume is detached

To improve UX, the implementation adds a hint for offline replica building

BTW, when a SPDK volume is degraded, can we add a similar hint to inform users that, the rebuilding will be triggered when the volume is in maintenance mode?

UX LGTM

Hello @smallteeths
Can you help with the idea?
If a spdk volume is attached, degraded and disableFrontend=false, add a hint for users.
Thank you.

Ok

The UI condition for judgment is as follows.

!volume.disableFrontend && volume.backendStoreDriver === ‘spdk’ && volume.state === ‘attached’

Add alert The volume rebuilding will be triggered

Moving to ready for testing, QA can follow the description to verify the UI part.

• After creating a volume, we can verify that the Offline Replica Rebuilding option values ignored (default value), disabled, and enabled are shown in the Longhorn UI.
• We can update the Offline Replica Rebuilding on the volume page.
• When a SPDK volume is degraded, a warning message will remind users that The volume rebuilding will be automatically triggered after detachment.
