Cannot migrate VM back from LVM storage

[Hawk]

Hi.

I've recently added an LVM thick storage to my PVE cluster which is a LUN shared between 4 of 5 nodes and everything works just fine except VM migration. I migrated VM from the 5th node which only has local storage to different node and shared LVM storage. Now I can't migrate it back. When trying to migrate (online) there is no option to select target storage and the migration fails complaning that LVM storage is not available on target node (which is true).

I also tried to migrate via CLI using:

qm migrate 104 node1 --online --with-local-disks --targetstorage node1-data

but this doesn't work either and gives the same error:

2025-09-08 17:01:43 ERROR: migration aborted (duration 00:00:00): storage 'lunlvm' is not available on node 'node1'

The workaround was to move disk between shared LVM and a local storage and then the option to choose storage during migration has reappeared and I was able to migrate my VM back.

If I had no local storage on the other nodes I'd be stuck with that VM on undesired nodes. It would be nice to allow such migration directly by allowing to choose the target storage if the source one is shared LVM.

Hello,

This means the VM you're trying to migrate has one or more disks stored on a storage backend called lunlvm, but that storage is not defined or accessible on the target node (node1). Proxmox requires all referenced storage types to exist on both source and destination nodes for migration to succeed.

Hi,
thank you for the report. This is a known issue: https://bugzilla.proxmox.com/show_bug.cgi?id=3229 Unfortunately, I had lost track of it and am still busy with other stuff right now.

Thanks for the info Fiona. Any chances this will be fixed with some upcoming updates to always allow to choose target storage manually?

I'm not working on in right now, so rather unlikely if nobody else wants to pick it up in the meantime. But I've re-added it to my TODO list.
