Description

Hi,
Is there a way to "load" osd disks of a CephFS array on to a new OSD server without re-initializing them?
The new server "sees" them and "sees" the LVM configuration.

Any help on re-mounting osd disks on different server?

Assuming the ceph.conf is correct, and if they are LVM bluestore, you can normally start the detected osds with `ceph-volume lvm activate --all`

Thank you.
I'll check it the next time I need to replace a server...
