[PVE-User] storage migration failed: error with cfs lock 'storage-nfs-scratch': unable to create image: got lock timeout - aborting command

[Marco Gaiarin]

We are trying to move some VMs disks from a cluster (PVE 5, storage LVM
thin), to a storage of type NFS (a PVE 6 server, debian buster standard
NFS server), usin QCOW as destination file/image format.

We have correctly move some smaller disks (200GB), but if we try to
move a 'big' disk, we got:

	Sep 14 22:48:18 pveod1 pvedaemon[31552]: <root at pam> starting task UPID:pveod1:00007BE2:A90E5224:61410A92:qmmove:100:root at pam:
	Sep 14 22:49:18 pveod1 pvedaemon[31552]: <root at pam> end task UPID:pveod1:00007BE2:A90E5224:61410A92:qmmove:100:root at pam: storage migration failed: error with cfs lock 'storage-nfs-scratch': unable to create image: got lock timeout - aborting command

Only this log row appear, no kernel/nfs errors in nfs server or source
machine.


I've tried to google for this error, or for 'nfs lock timeout' but
nothing relevant (to me) appear.

Someone have some feedback? Thanks.
