We have a FreeBSD 12.3 guest machine that works well on an RBD volume until it is live migrated to another node (on Proxmox).  After migration, the processes almost all go into D state (waiting for this disk) and they don't exist from it (ie they don't "get" the disk the requested. I'm not sure what it causing this, so I'm asking here if anyone has come across such a problem?
