Usually it should also accept the device path (although I haven't
tried that in Octopus yet), you could try `ceph-volume lvm prepare
--data /path/to/device` first and then activate it. If that doesn't
work, try to create a vg and lv and try it with LVM syntax
(ceph-volume lvm prepare --data {vg}/{lv}). I don't have a cluster at
hand right now so I can't double check. But I find it strange that it
doesn't accept the device path, maybe someone with more Octopus
experience can chime in.

I didn't notice that. Have you tried this multiple times with the

Thanks Eugen for your fast response. Yes, I have tried it multiple
times, but I'm trying again right now just to be sure the outcome is
the same.
- ceph.log and ceph-mgr.node1.log don't have much.
- syslog itself doesn't show anything Ceph related.
- ceph-volume logs show the following:

It looks like it is probing the disk for LVM information. Do I need
to manually prepare this disk first with LVM before I can use it?
Currently the disk should be clean. Any prior filesystems should be
wiped completely, no RAID, GRUB, or boot partitions on it either.
