Hi.
Dual node cluster, btrfs type storage, last update for btrfs-progs (5.16.2-1~bpo11+1) breaks migration task for both vms and lxc containers.
Migration log for simple uefi vm, no spanshots, nothing fancy:
Going back to btrfs-progs=5.10.1-2 fixes the issue:
Maybe there is someone else testing btrfs storage in a cluster configuration that can verify this issue?
