IMMEDIATE ACTIONS REQUIRED

-

After fix should show:

- +
    +
  1. SSH to cluster: ssh root@{{ hostname }}
    2. +
  2. Check overall status: pvecm status
    3. +
  3. Review HA logs: journalctl -u pve-ha-lrm -u pve-ha-crm -n 20
    4. +
  4. Check network connectivity between nodes
    5. +
  5. Verify all cluster nodes are online
    6. +
-

STEP-BY-STEP FIX

- -

Step 1 - Fix Qdevice:

-
-
systemctl restart corosync-qdevice
-
sleep 5
-
corosync-qdevice-tool -s
-
- -

Step 2 - Verify status:

-
-
pvecm status
-
-

LOOK FOR: Total votes: 3 (not 2!) and Qdevice (votes 1)

- -

Bottom line: The cluster works now but has no tie-breaker vote.
-One node failure = no quorum = VMs can't migrate.

+

Warning: Issues detected in the cluster. Immediate attention required to ensure high availability.
