A Ceph OSD nowadays needs a logical volume because it stores crucial
metadata in the LV tags. This helps to activate the OSD.
IMHO you will have to redeploy the OSD to use LVM on the disk. It does
not need to be the whole disk if there is other data on it. It should
be sufficient to make /dev/sdb1 a PV of a new VG for the LV of the OSD.
thank you for the suggestion. I understand the need for Ceph OSDs to use
LVM due to the metadata stored in LV tags. However, I’m facing a
challenge with the disk replacement process. Since I’ve already migrated
the OSDs to use |ceph-volume|, I was hoping that |cephadm| would handle
the creation of LVM structures automatically. Unfortunately, it doesn’t
seem to recreate these structures on its own when replacing a disk, and
manually creating them isn’t ideal because |ceph-volume| uses its own
specific naming conventions.
Do you have any recommendations on how to proceed with |cephadm| in a
way that it can handle the LVM setup automatically, or perhaps another
method that aligns with the conventions used by |ceph-volume|?
