Hi,

I'm trying to move back some VM from Ceph to Local (same node).
That's done with move disk option, right?

When I move the disk, it gets created in local, but the the process hangs at 100%, and the VM keeps using the one from Ceph.
I cannot delete the disks created in local: "a vm with vmid exists".

Is there something wrong?

Kernel Version

Linux 5.15.39-3-pve #2 SMP PVE 5.15.39-3 (Wed, 27 Jul 2022 13:45:39 +0200)
PVE Manager Version

pve-manager/7.2-7/d0dd0e85
 
Hi,
please post the output of pveversion -v and qm config <ID> as well as the complete task log for the Move Disk operation. Are there any errors in /var/log/syslog or with ceph -w during the operation?

To get rid of the left-over disk, you can use qm rescan --vmid <ID> on the CLI and then remove the unused disk from the VM's Hardware tab in the UI.
 
Hi,

I actually already updated the packages, ceph was old 16.x when this happened.

I actually solved: it only continues to log "transferred 100%" for a couple of minutes before starting to delete the old disk.
I also properly removed the ghost disks.
I also do not have the old logs at hand...

Thank you very much

Glad to hear :) So likely it just needed time to flush everything/finish the operation. Out of curiosity: Was the VM running during the move? How large is the disk?
 
Do you have a cache setting active for the disk? I tried to reproduce the issue here and that causes high IO wait for me.
