Hi, Keep in mind that /var/lib/ceph/osd/ is a tmpfs which is created by 'ceph-bluestore-tool' on OSD startup. All the data in there comes from the lvtags set on the LVs. So I *think* you can just rename the Volume Group and rescan with ceph-volume. Wido On 1/28/20 10:25 AM, Stolte, Felix wrote:

Hi all,

I would like to rename the logical volumes / volume groups used by my OSDs. Do I need to change anything else than the block and block.db links under /var/lib/ceph/osd/<osdid>?
