Hi, Installing ceph from the debian unstable repository (ceph version 14.2.6 (f0aa067ac7a02ee46ea48aa26c6e298b5ea272e9) nautilus (stable), debian package: 14.2.6-6) has fixed things form me.

Jan,
In trying to recover my OSDs after the upgrade from Nautilus described earlier, I eventually managed to make things worse to the point where I'm going to scrub and fully reinstall. So I zapped all of the devices on one of my nodes and reproduced the ceph-volume lvm create error I mentioned earlier, using the procedure from https://docs.ceph.com/docs/mimic/rados/configuration/bluestore-config-ref/ to lay out the LVs and issue ceph-volume lvm create. As I was concerned that maybe it was a size thing, I only create a 4TB block LV for my first attempt, and the full 12TB drive for my second attempt.
The output is:

Hi,
I've run into the same issue while testing:
ceph version 14.2.6 (f0aa067ac7a02ee46ea48aa26c6e298b5ea272e9) nautilus (stable)
debian bullseye
Ceph was installed using ceph-ansible on a vm from the repo http://download.ceph.com/debian-nautilus
The output of `sudo sh -c 'CEPH_VOLUME_DEBUG=true ceph-volume --cluster test lvm batch --bluestore /dev/vdb'` has been attached.
Thx, I opened https://tracker.ceph.com/issues/43868. This looks like a bluestore/osd issue to me, though it might end up being ceph-volumes fault.
Also worth noting might be that '/var/lib/ceph/osd/test-0/fsid' is empty (but I don't know too much about the internals)

Jan,
Unfortunately I'm under immense pressure right now to get some form of Ceph into production, so it's going to be Luminous for now, or maybe a live upgrade to Nautilus without recreating the OSDs (if that's possible).
The good news is that in the next couple months I expect to add more hardware that should be nearly identical. I will gladly give it a go at that time and see if I can recreate. (Or, if I manage to thoroughly crash my current fledgling cluster, I'll give it another go on one node while I'm up all night recovering.)
If you could tell me where to look I'd gladly read some code and see if I can find anything that way. Or if there's any sort of design document describing the deep internals I'd be glad to scan it to see if I've hit a corner case of some sort. Actually, I'd be interested in reading those documents anyway if I could.
Thanks.

All,
I've just spent a significant amount of time unsuccessfully chasing the _read_fsid unparsable uuid error on Debian 10 / Natilus 14.2.6. Since this is a brand new cluster, last night I gave up and moved back to Debian 9 / Luminous 12.2.11. In both cases I'm using the packages
from Debian Backports with ceph-ansible as my deployment tool.
Note that above I said 'the _read_fsid unparsable uuid' error. I've searched around a bit and found some previously reported issues, but I did not see any conclusive resolutions.
I would like to get to Nautilus as quickly as possible, so I'd gladly provide additional information to help track down the cause of this symptom. I can confirm that, looking at the ceph-volume.log on the OSD host I see no difference between the ceph-volume lvm batch command generated by the ceph-ansible versions associated with these two Ceph releases:
ceph-volume --cluster ceph lvm batch --bluestore --yes --block-db-size 133358734540 /dev/sdc /dev/sdd /dev/sde /dev/sdf /dev/sdg /dev/sdh /dev/sdi /dev/sdj /dev/nvme0n1
Note that I'm using --block-db-size to divide my NVMe into 12 segments as I have 4 empty drive bays on my OSD servers that I may eventually be able to fill.
My OSD hardware is:

I'd send the output of ceph-volume inventory on Luminous, but I'm getting -->: KeyError: 'human_readable_size'.
Please let me know if I can provide any further information.
Mind re-running you ceph-volume command with debug output enabled: CEPH_VOLUME_DEBUG=true ceph-volume --cluster ceph lvm batch --bluestore ...
Ideally you could also openen a bug report herehttps://tracker.ceph.com/projects/ceph-volume/issues/new
Thanks!
Thanks.
