Hi all,

We have removed an OSD disk from a server in our office cluster, 
removing partitions (with --cleanup 1) and that has made the server 
unable to boot (we have seen this in 2 servers in a row...)

Looking at the command output:

--- cut ---
root at sanmarko:~# pveceph osd destroy 5 --cleanup 1
destroy OSD osd.5
Remove osd.5 from the CRUSH map
Remove the osd.5 authentication key.
Remove OSD osd.5
Unmount OSD osd.5 from  /var/lib/ceph/osd/ceph-5
remove partition /dev/sda1 (disk '/dev/sda', partnum 1)
The operation has completed successfully.
remove partition /dev/sdd7 (disk '/dev/sdd', partnum 7)
Warning: The kernel is still using the old partition table.
The new table will be used at the next reboot or after you
run partprobe(8) or kpartx(8)
The operation has completed successfully.
wipe disk: /dev/sda
200+0 records in
200+0 records out
209715200 bytes (210 MB, 200 MiB) copied, 1.29266 s, 162 MB/s
wipe disk: /dev/sdd
200+0 records in
200+0 records out
209715200 bytes (210 MB, 200 MiB) copied, 1.00753 s, 208 MB/s
--- cut ---

Boot disk is SSD, look that scripts says it is wiping /dev/sdd!! It 
should do that to the journal partition? (dev/sdd7)

This cluster is on PVE 5.3 .

Cheers
Eneko
