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.
Thanks and best regards,
