OSD issues after migration

[luphi]

hey there,

I migrated a ceph node to new hardware. After moving the OSDs, they won't come up again. All pgs are unknown, all OSDs are down. The GUI shows them as filestore, but they are definitely bluestore.

The old server was originally installed with PVE 4.4/hammer and migrated from time to time up to the latest 5.1/luminous.

The new server was installed directly with 5.1/luminous. Any suggestion how to recover them?

Cheers,
luphi

So, you install PVE 5.1 on the new hardware and move osd disks from old one to new?
IMO it will not work that way.
