How do I recover a VJBOD pool error after a remote HA failover?

Scenario

I have created a VJBOD storage pool on a local NAS that uses VJBOD disks created from LUNs on a remote high-availability (HA) cluster. When a failover occurs in the remote HA cluster, the VJBOD storage pool status on my local NAS changes to "Error", and all ongoing I/O operations are interrupted.

Root Cause

Although the VJBOD service switches to the other node during an HA failover, this process is still registered as a connection loss. This causes the operating system on the local NAS to detect I/O errors and change the VJBOD storage pool status to "Error" as a data protection measure. This is currently the expected behavior.

Solution

You can manually recover the VJBOD storage pool without deleting or rebuilding it by following these steps:

  1. Verify the remote HA cluster has recovered from the failover.
    1. Log in to the HA cluster as an administrator.
    2. Open High Availability Manager.
    3. Go to Cluster.
    4. Verify the nodes have switched roles.
    5. Verify the cluster status is "Good".
  2. Recover the VJBOD storage pool on the local NAS.
    1. Log in to the local NAS as an administrator.
    2. Open Storage Manager.
    3. Go to Storage Space.
    4. Identify the VJBOD storage pool with the "Error" status.
    5. Under Action, click ⋮ and select Manage.
      The pool management window opens.
    6. Go to the RAID tab.
    7. Click Manage and select Recover Storage Pool.
      The system recovers the VJBOD storage pool.
    8. Once the recovery is complete, the VJBOD storage pool status changes to "Ready".
      You can now access the data in the pool again.
Important
Because VJBOD does not currently support HA failovers, you would need to manually recover your VJBOD storage pool every time a failover occurs on the remote HA cluster. Before you continue using this setup, please evaluate whether this limitation meets your production requirements. You can consider other methods of storage expansion or use LUNs from a standalone NAS instead of a NAS in an HA cluster.
