Hi, I am trying to Re-Add a OSD after replacing the disk, I am running, ceph-volume lvm create --bluestore --osd-id 41 --data ceph-dm-41/block-dm-41 And I get, --> AttributeError: module 'ceph_volume.api.lvm' has no attribute 'is_lv' My Ceph Version is "osd": { "ceph version 15.2.9 (357616cbf726abb779ca75a551e8d02568e15b17) octopus (stable)": 359 I understand this is a BUG and fix is in 15.2.10. Is there no otherway than to upgrade? And is it safe to upgrade when there are some backfill operations in Progress?
