GitHub user GerorgeEG added a comment to the discussion: ACS is not able to 
restart VM during HA process

Hi @shwstppr yes capacity is there and we are using storage tags to place VM on 
correct storage type but we figured out something else. 

VM's which were down due to host failure were not able get powered on even by 
admin on another hosts in same cluster. We did some more log analysis and find 
out it an issue with storage lock.

org.libvirt.LibvirtException: internal error: process exited while connecting 
to monitor: 2025-02-22T06:42:45.557175Z qemu-kvm: -blockdev 
{"node-name":"libvirt-3-format","read-only":false,"cache":{"direct":true,"no-flush":false},"driver":"qcow2","file":"libvirt-3-storage","backing":"libvirt-4-format"}:
 **Failed to get "write" lock.**

We remounted the NFS share with below options and then HA start working as 
expected.

NFS mount options
**rw,vers=3,sync,hard,_netdev,nolock**

Now can you please help as we are not sure the if we should continue with lock 
option or is there anything else. Looking forward for suggestions with best 
approach.
