Can't migrate VM to different storage volume

[js-monroe]

Hi, Been using Proxmox on a test server and realize I want to commit a more substantial machine to using this awesome VE. Only to learn that differently named storage volumes cannot be migrated using the Web GUI.

Okay then, no problem.

So I try using the console and this happens:

qm migrate 102 proxmox1 --targetstorage SSD-500GB --online
2023-08-08 21:02:59 starting migration of VM 102 to node 'proxmox1' (192.168.0.103)
2023-08-08 21:02:59 found local disk 'RAID-MIRROR-1TB:vm-102-disk-0' (attached)
2023-08-08 21:02:59 found local disk 'local:iso/debian-11.7.0-amd64-netinst.iso' (attached)
2023-08-08 21:02:59 can't migrate local disk 'RAID-MIRROR-1TB:vm-102-disk-0': can't live migrate attached local disks without with-local-disks option
2023-08-08 21:02:59 can't migrate local disk 'local:iso/debian-11.7.0-amd64-netinst.iso': can't live migrate attached local disks without with-local-disks option
2023-08-08 21:02:59 ERROR: Problem found while scanning volumes - can't migrate VM - check log
2023-08-08 21:02:59 aborting phase 1 - cleanup resources
2023-08-08 21:02:59 ERROR: migration aborted (duration 00:00:00): Problem found while scanning volumes - can't migrate VM - check log

*So I guess maybe the logs will be helpful? But which ones?
Any attention/help offered will be greatly appreciated. I've been banging away at this for a few days off and on reading all sorts of tutorials, but no luck so far. I'm considering just rebuilding the VM's fresh on the new server at this point.

Hi, as the log state rather clearly, you cannot live migrate a VM with attached local disks. If you want to migrate them regardless, you will have to also pass the with-local-diks flag. See excerpt from man qm

       --with-local-disks <boolean>
           Enable live storage migration for local disk

Also, you might want to detach the debian install iso which is still attached and probably not needed anymore.

Thanks for the reply. I added the --with-local-disks flag and it didn't work initially. But when I detached the debian ISO and issued the command again, then it worked after that.
