[ceph-users] Re: Recover OSDs from folder /var/lib/ceph/uuid/removed

Well, things I would do: - add the keyring to ceph auth ceph auth add osd.XX osd 'allow *' mon 'allow rwx' -i /var/lib/ceph/uuid(osd.XX/keyring - add OSD to crush ceph osd crush set osd.XX 1.0 root=default ... - create systemd service systemctl enable ceph-uuid@osd.XX.service Is there something I am missing?

Hello,

is it possible to recover an OSD if it was removed?

The systemd service was removed but the block device is still listed under

lsblk

and the config files are still available under

/var/lib/ceph/uuid/removed

It is a containerized cluster. So I think we need to add the cephx entries, use ceph-volume, crush, and so on.
