Hi all, I'm trying to install ceph on a 3 nodes pve cluster. In one of the nodes, from the graphical interface, I have added a device to OSD but after a some big time (1 hour or more) I have stopped the procedure. Now I can't even clean the device becasue the command "ceph-volume lvm zap /dev/sdx --destroy" never stop.
Please someone can help me to find a way to clean the device and help me newly add to OSD?

Many thanks

The task of adding a new OSD took an hour long before you cancelled it?

That does sound wrong. Is the disk okay?

You can fully wipe it with sgdisk -Z /dev/sdX
 
Thanks Aaron, I have clean the hard drive with gdisk and I have add the drive to osd again. These are the logs:

and there is no way to go further. I've not noticed that in these logs is shown an error:
stderr: 2021-03-03 14:15:15.315 7fd1f86d9700 -1 auth: unable to find a keyring on /etc/pve/priv/ceph.client.bootstrap-osd.keyring: (2) No such file or directory

should be the cause of the problem? Do you know how can I solve this problem?

That's seems ok, isn't it?

Run a ceph osd tree and check if you have stray OSD. If so, remove it. Then you may need to delete the auth key as well (ceph auth del osd.X). After that try again.

yes never end, I have to stop myself. Should be tied to the fact that this node has proxmox 6.2.12 but other nodes have proxmox 6.3.4?

yes the disk is new and it is ok.

That seems to works but doesn't remove the disk from "out" OSDs. There is a way to remove this device ever from out OSDs?

This is the oputput of ceph osd tree:
ceph osd tree
ID CLASS WEIGHT TYPE NAME STATUS REWEIGHT PRI-AFF
-1 3.49319 root default
-3 3.49319 host pve03
1 ssd 1.74660 osd.1 up 1.00000 1.00000
2 ssd 1.74660 osd.2 up 1.00000 1.00000
0 0 osd.0 down 0 1.00000
3 0 osd.3 down 0 1.00000
4 0 osd.4 down 0 1.00000
Click to expand...
but I can't understand what you mean with "check if you have stray OSD". Any way to remove the OSDs failed devices I run
Code: 
ceph osd rm osd.{0,3,4}
and now the output of ceph osd tree is:
ID CLASS WEIGHT TYPE NAME STATUS REWEIGHT PRI-AFF
-1 3.49319 root default
-3 3.49319 host pve03
1 ssd 1.74660 osd.1 up 1.00000 1.00000
2 ssd 1.74660 osd.2 up 1.00000 1.00000
Click to expand...
Furthermore as you suggested me I have removed the auth keys as well with the command
Code: 
ceph auth del osd.{4,3,0}
. Any way If I try to add the sdx device to the OSDs with the command
Code: 
pveceph osd create /dev/sdx
I I get the error:
device '/dev/sdx' is already in use
Click to expand...
Have you any idea how to clean the failed devices from proxmox in a way I can try to re-add to CEPH OSDs

Thank you very much

I run the command that aaron suggested me... in effect proxmox says that is in use but it isn't: as I have wrote I have only cancel the osd creations on the drive...

Do you know how to reset ceph in a way I can try to configure/install it from zero?

Alwin Antreich said:
It's not an issue with ceph. Either you will need to re-run the command or in a later consequence do a reboot. The disk might have not been released by the kernel.
Click to expand...
You are right. rebooting the server the drive has been released.

Aligning packages between nodes installing all updates available, solve the adding drive to OSDs problem found early

Thank you very much!
