Re: [EXTERNAL] [Pacific] ceph orch device ls do not returns any HDD

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'.

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 253:1    0 465.8G  0 lvm
sdc 8:32   1 232.9G  0 disk
`-ceph--b27d7a07--278d--4ee2--b84e--53256ef8de4c-osd--block--45c8e92c--caf9--4fe7--9a42--7b45a0794632 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.

Any idea of what is wrong ?

I'm still trying to understand what can be wrong or how to debug this situation where Ceph cannot see the devices.

The device :dev/sdc exists:

   [root@mostha1 ~]# cephadm shell lsmcli ldl
   Inferring fsid 250f9864-0142-11ee-8e5f-00266cf8869c

   /dev/sdc | 50024e920387fa2c | PATA/SATA | S2B5J90ZA02494 | Good

But I cannot do anything with it:

   [root@mostha1 ~]# cephadm shell ceph orch device zap
   mostha1.legi.grenoble-inp.fr /dev/sdc --force
   Inferring fsid 250f9864-0142-11ee-8e5f-00266cf8869c

   'mostha1.legi.grenoble-inp.fr'

Since I moved from octopus to Pacific.
