Hi all,
ending with git bisect just now shows:
4fc6bc394dffaf3ad375ff29cbb0a3eb9e4dbefc is the first bad commit
commit 4fc6bc394dffaf3ad375ff29cbb0a3eb9e4dbefc
Author: Zack Cerza <zack@xxxxxxxxx>
Date: Tue May 17 11:29:02 2022 -0600
ceph-volume: Optionally consume loop devices
A similar proposal was rejected in #24765; I understand the logic
behind the rejection, but this will allow us to run Ceph clusters on
machines that lack disk resources for testing purposes. We just need to
make it impossible to accidentally enable, and make it clear it is
unsupported.

I will try to investigate next week but if some Ceph expert developpers
can have a look at this commit ;-)
Have a nice week-end

Hi all,
I'm trying to catch the faulty commit. I'm able to build Ceph from the
git repo in a fresh podman container but at this time, the lsblk
command returns nothing in my container.
In ceph containers lsblk works
So something is wrong with launching my podman container (or different
from launching ceph containers) and I cannot find what.
Any help about this step ?
Thanks
Patrick

Trying to resend with the attachment.
I can't really find anything suspicious, ceph-volume (16.2.11) does
recognize /dev/sdc though:

But apparently it just stops after that. I already tried to find a
debug log-level for ceph-volume but it's not applicable to all
subcommands.
The cephadm.log also just stops without even finishing the "copying
blob", which makes me wonder if it actually pulls the entire image? I
assume you have enough free disk space (otherwise I would expect a
message "failed to pull target image"), do you see any other warnings
in syslog or something? Or are the logs incomplete?
Maybe someone else finds any clues in the logs...
Regards,
Eugen

Hi Eugen,
You will find in attachment cephadm.log and cepĥ-volume.log. Each
contains the outputs for the 2 versions. v16.2.10-20220920 is really
more verbose or v16.2.11-20230125 does not execute all the detection
process

Good catch, and I found the thread I had in my mind, it was this
exact one. :-D Anyway, can you share the ceph-volume.log from the
working and the not working attempt?
I tried to look for something significant in the pacific release
notes for 16.2.11, and there were some changes to ceph-volume, but
I'm not sure what it could be.
Zitat von Patrick Begou <Patrick.Begou@xxxxxxxxxxxxxxxxxxxxxx>:
I've ran additional tests with Pacific releases and with
"ceph-volume inventory" things went wrong with the first v16.11
release (v16.2.11-20230125)

May be this could help to see what has changed ?

That's really strange. Just out of curiosity, have you tried
Quincy (and/or Reef) as well? I don't recall what inventory does
in the background exactly, I believe Adam King mentioned that in
some thread, maybe that can help here. I'll search for that
thread tomorrow.

Can you check which cephadm version is installed on the host?
And then please add (only the relevant) output from the
cephadm.log when you run the inventory (without the --image
<octopus>). Sometimes the version mismatch on the host and the
one the orchestrator uses can cause some disruptions. You could
try the same with the latest cephadm you have in
/var/lib/ceph/${fsid}/ (ls -lrt
/var/lib/ceph/${fsid}/cephadm.*). I mentioned that in this
thread [1]. So you could try the following:
$ chmod +x /var/lib/ceph/{fsid}/cephadm.{latest}
$ python3 /var/lib/ceph/{fsid}/cephadm.{latest} ceph-volume
inventory
Does the output differ? Paste the relevant cephadm.log from
that attempt as well.

Your response is a bit confusing since it seems to be mixed
up with the previous answer. So you still need to remove the
OSD properly, so purge it from the crush tree:
ceph osd purge 2 --force --yes-i-really-mean-it (only in a
test cluster!)
If everything is clean (OSD has been removed, disk has been
zapped, lsblk shows no LVs for that disk) you can check the
inventory:
cephadm ceph-volume inventory
Please also add the output of 'ceph orch ls osd --export'.
Zitat von Patrick Begou <Patrick.Begou@xxxxxxxxxxxxxxxxxxxxxx>:
Hi Eugen,
- the OS is Alma Linux 8 with latests updates.
- this morning I've worked with ceph-volume but it ends with
a strange final state. I was connected on host mostha1 where
/dev/sdc was not reconized. These are the steps followed
based on the ceph-volume documentation I've read:
[root@mostha1 ~]# cephadm shell
[ceph: root@mostha1 /]# ceph auth get client.bootstrap-osd >
/var/lib/ceph/bootstrap-osd/ceph.keyring
[ceph: root@mostha1 /]# ceph-volume lvm prepare --bluestore
--data /dev/sdc
Now lsblk command shows sdc as an osd:
....
sdb 8:16 1 465.8G 0 disk
`-ceph--08827fdc--136e--4070--97e9--e5e8b3970766-osd--block--7dec1808--d6f4--4f90--ac74--75a4346e1df5

253:5 0 232.8G 0 lvm
Then I've tried to activate this osd but it fails as in
podman I have not access to systemctl:
[ceph: root@mostha1 /]# ceph-volume lvm activate 2
45c8e92c-caf9-4fe7-9a42-7b45a0794632

Running command: /usr/bin/systemctl start ceph-osd@2
stderr: Failed to connect to bus: No such file or directory
--> RuntimeError: command returned non-zero exit status: 1
[ceph: root@mostha1 /]# ceph osd tree
And now I have now I have a strange status for this osd.2:
[ceph: root@mostha1 /]# ceph osd tree

I've tried to destroy the osd as you suggest but even if the
command returns no error I still have this osd even if
"lsblk" do not show any more /dev/sdc as a ceph osd device.

Hi,
just wondering if 'ceph-volume lvm zap --destroy /dev/sdc'
would help here. From your previous output you didn't
specify the --destroy flag.
Which cephadm version is installed on the host? Did you
also upgrade the OS when moving to Pacific? (Sorry if I
missed that.

Hi all,
still stuck with this problem.
I've deployed octopus and all my HDD have been setup as
osd. Fine.
I've upgraded to pacific and 2 osd have failed. They have
been automatically removed and upgrade finishes. Cluster
Health is finaly OK, no data loss.
But now I cannot re-add these osd with pacific (I had
previous troubles on these old HDDs, lost one osd in
octopus and was able to reset and re-add it).
I've tried manually to add the first osd on the node
where it is located, following
https://docs.ceph.com/en/pacific/rados/operations/bluestore-migration/
(not sure it's the best idea...) but it fails too. This
node was the one used for deploying the cluster.
