Looks very similar to tracker 37490, LVs list is being created multiple times. I'll start with this one.
#2 Updated by Rishabh Dave over 3 years ago
- Pull request ID set to 30102
The PR was closed since ceph-volume development moved in a different direction -- instead of improving filter method in container classes (namely, Volumes, PVolumes and VolumeGroups) we got rid of them in favour of filters provided by LVM commands. See https://github.com/ceph/ceph/pull/32493 and https://github.com/ceph/ceph/pull/35937. Closing this ticket too.
