Hello,
in our cluster we have one node with SSD, which are used, but we cannot see
it in "ceph orch device ls". Everything als looks OK. For better
understanding, the diskname is /dev/sda, it's osd.138:
~# lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 1 7T 0 disk
~# wipefs /dev/sda
DEVICE OFFSET TYPE UUID LABEL
sda 0x0 ceph_bluestore
~# ceph osd tree
-9 15.42809 host ceph06
138 ssd 6.98630 osd.138 up 1.00000 1.00000
The file ceph-osd.138.log does not look unusal to me.
ceph-volume.log show that the SSD is found by the "lsblk" command of the
volume processing.
It is not possible to add the SSD by
"# ceph orch daemon add osd ceph06:/dev/sda
Error message in this case is a question asking if it is already used, even
if the SSD is fully wiped via "wipefs -a" or by overwriting the entire disk
with the dd command. But It is possible to add it to the cluster by using
the option "--method raw".
Do you have an idea what happened here and how can I debug this behaviour?
