Description
When using Ceph RBD as primary storage on KVM, the agent currently tries to
run:
mountpoint -q /mnt/<uuid>
This fails because RBD pools are not mounted like NFS or other network
filesystems.
As a result, snapshot and template operations fail with errors such as:
libvirt failed to mount storage pool <uuid> at /mnt/<uuid>
This patch updates LibvirtStorageAdaptor to skip the mountpoint check when
the storage pool type is RBD.
It prevents false errors while keeping the logic unchanged for NFS/NetFS
pools.
Types of changes
Bug fix (non-breaking change which fixes an issue)
Bug Severity
Major (affects snapshot/template functionality on Ceph RBD)
How Has This Been Tested?
CloudStack 4.21.0.0 + Ceph RBD backend (client.cloudstack user)
Created multiple VM snapshots → successfully registered in Ceph
Created templates from snapshots → completed without mountpoint errors
Verified no regressions on other pool types (NFS untouched)
Checked agent.log: no further mountpoint failures for RBD pools
