Hi all, this is a follow-up on "reboot breaks OSDs converted from ceph-disk to ceph-volume simple". I converted a number of ceph-disk OSDs to ceph-volume using "simple scan" and "simple activate". Somewhere along the way, the OSDs meta-data gets rigged and the prominent symptom is that the symlink block is changes from a part-uuid target to an unstable device name target like: before conversion: block -> /dev/disk/by-partuuid/9123be91-7620-495a-a9b7-cc85b1de24b7 after conversion: block -> /dev/sdj2 This is a huge problem as the "after conversion" device names are unstable. I have now a cluster that I cannot reboot servers on due to this problem. OSDs randomly re-assigned devices will refuse to start with: 2021-03-02 15:56:21.709 7fb7c2549b80 -1 OSD id 241 != my id 248 Please help me with getting out of this mess.
These paths might be coming from /etc/ceph/osd/*.json files. Have your tried editing the files to replace /dev/sdXX path with the by-partuuid path?
