[SOLVED] Adding existing disk from storage to vm

[maturos]

I've a VM with two disks. The first disk is small and contains the configuration of my cloud service. The second is about 2,5 TB large contains the data and is therfore excluded from backup (What Could Possibly Go Wrong?). Now i needed to restore the backup and my second disk is detached and no longer in my VM config. It's still in my storage list:


How can I get my data disk reattached to the VM?

Click on the unattached disk, then edit to add it to the VM again.

If it isn't listed in the VMs hardware tab you can run qm rescan

@Dunuin I dont see "unattached" disk in his screenshot. Perhaps "qm rescan" will help to get it there.
Of course, the "missing" disk must be located in there correct directory, i.e. same place where disk-0 is.

Thank you for your fast help. This confirms me that the disk must be appear as unattached in the hardware section. Unfortunally `qm rescan` resulted in an error I can't interpret:

And qm rescan --vmid 102?

You probably have a stanza in your /etc/pve/storage.cfg that points to pve/data , but it does not exist any more.
What does "pvesm status" show", you may need to clean up your config.

MY storage.cfg is following:

dir: local
        path /var/lib/vz
        content backup,vztmpl
        shared 0

lvmthin: local-lvm
        thinpool data
        vgname pve
        content images,rootdir

dir: ISO
        path /media/ISO
        content iso,vztmpl
        shared 0

dir: Disks
        path /media/disks
        content rootdir,images
        nodes pve
        shared 0

dir: Backups
        path /media/backups
        content backup
        nodes pve
        shared 0

could it be the local-lvm?
I'm just using "Disks", "ISOs" and "Backup". Didn't wanted to touch something. Local-lvm seems to make problems.

Is it safe to remove it from the config if it's broken since i can think?

With eyes squinted and fingers crossed, I removed local-lvm with the GUI. It worked:

root@pve:~# qm rescan --vmid 102

VM 102 add unreferenced volume 'Disks:102/vm-102-disk-1.qcow2' as 'unused0' to config

Thank you and a big hug for you all, you saved my evening!
