Storage Plane

Fresh Cluster Cannot Be Activated

Symptom: After a fresh deployment, the cluster cannot be activated. The activation process hangs or fails and the storage nodes show n/0 disks available in the disks column (sbcli storage-node list).

1. Shutdown all storage nodes: sbcli storage-node shutdown --force
2. Force remove all storage nodes: sbcli storage-node remove --force
3. Delete all storage nodes: sbcli storage-node delete
4. Re-add all storage nodes. The disks should become active.
5. Try to activate the cluster.

Storage Node Health Check Shows Health=False

Symptom: The storage node health check returns health=false (sbcli storage-node list).

1. First run sbcli storage-node check.
2. If the command keeps showing an unhealthy storage node, suspend, shutdown, and restart the storage node.

Danger

Never shutdown or restart a storage node while the cluster is in rebalancing state. This can lead to potential I/O operation. This is independent of the high-availability status of the cluster.

Check the cluster status with any of the following commands:

sbcli cluster list
sbcli cluster get <cluster-id>
sbcli cluster show <cluster-id>
