Unused disk problem with backup/restore

[Andrew Hart]

I have backed up and restored a few VMs from another proxmox. After the restore has completed the hardware of the VM sometimes has two disks of the same image :
Hard Disk (virtio0) disk_vm:vm-108-disk,size=50G
Unused Disk 0 disk_ct:vm-108-disk-1

The ceph pool is called "disk" and those are the default added storages. I know, from trying, that removing the "Unused Disk 0" results in a non-booting VM. The VM was never a container.

do you by any chance activated 'disk image' content type on the disk_ct storage?

when using our ceph tools, we create 2 storage definitions: <POOL>_vm and <POOL>_ct with the respective content types

so if disk_ct has the content 'disk images' it sees 2 disks for your vm, one on disk_vm and one on disk_ct
deleting one of them deletes the disk on the ceph pool

 

[Andrew Hart]

No, disk_ct is set to "Container" and disk_vm is set to "Disk image". Also it has only happened twice, not every time (from 4 so far)

 

[dcsapak]

can you post the output of 'pveversion -v'
this sounds like a bug that we already fixed

mhmm, yes i can reproduce it, can you please open a bug?
for the moment, just ignore the unused disk (it does not do anything, besides being there)
