VM migration and target storages

[Astaoth]

Hi,

I've a PVE cluster of two nodes, with a first node with a LVM storage and the second node with a ZFS one (and a different name). On both nodes, I've also a directory storage for specific VM images, with the same name.

In my understanding a VM live migration between a LVM and a ZFS storage should work. Also a migration between a storage with a given name to a storage with an other name should work too, I should have to indicate the target storage in the migration UI.

But now, I've a VM with a disk on the LVM storage and an other one in the directory storage that I would like to migrate on the other node. I can select the ZFS storage, but I would like to migrate the disks from the directory one to the target node storage of the same kind with the same name. Is it possible to indicate a target storage by volume to migrate instead of a global target ?

Did you not read the docs on clustering? Search the forum for "qdevice"

I actually read it. Would you mind to be a little less enigmatic about which section of the clustering doc are you refering to ?

Also, this issue has nothing to do with qdevices. This would be usefull only for splitbrain issues and HA, which, I'm not using making it fine to have only a 2-node cluster, as described in the clustering documentation. But this has nothing to do with a manual VM live migration from a node to an other one.

I guess there is no real solution for this issue at the moment, it doesn't look like it's possible to indicate a different target storage for only one vm disk, or to give a target volume by vm disk. I've migrated my ZFS proxmox to LVM and the live migration more or less work now.
