Why am I not able to create a VM from the template image in OpenShift Virtualization after the snapshot count of the Ceph volume has crossed 450?
Issue
- The user is unable to create a new VM from the golden image after creating 450+ VMs from the template.
- The snapshot count of the underlying Ceph volume of the template image crossed 450:
# rbd info csi-vol-577fa68a-4b37-479a-bf58-023a320af82c --pool mypool
rbd image 'csi-vol-577fa68a-4b37-479a-bf58-023a320af82c':
size 30 GiB in 7680 objects
order 22 (4 MiB objects)
snapshot_count: 454 <===
- The ceph rbd client is logging below message:
I0815 15:11:45.211253 1 controllerserver.go:536] ID: 3701 Req-ID: snapshot-ecd44693-7d3c-4021-aa39-502857abce2a snapshots count 454 on image: mypool/csi-vol-577fa68a-4b37-479a-bf58-023a320af82c reached configured hard limit 450
