Migrating VM(s) fails with 'Wrong medium type' on the target node.

[inside]

Dear community,

running here is a three node cluster of Proxmox VE 8.2 with the Linstor-DRBD-Backend enabled.

Live migration of VMs from one node to another has successfully being tested.

Now, when I want to migrate a VM (any of them) to another node, the task produces an error that reads:

--
[node3] kvm: -drive file=/dev/drbd/by-res/vm-101-disk-1/0,if=none,id=drive-scsi0,format=raw,cache=none,aio=io_uring,detect-zeroes=on: Could not open '/dev/drbd/by-res/vm-101-disk-1/0': Wrong medium type
--

The system log of the source node says:

Updates have been made since the last successful attempt of moving a VM, so that may be a reason for the problem?

Does or did anyone experience the same issue?

What kind of additional information would you need from me?

Any help is appreciated!

Kind regards

Hi @inside , welcome to the forum.

Your path to resolution might be faster if you ping Linbit about this.

Good luck
