Migrate Disk - fail on shared storage - unable to create image: got lock timeout - aborting command

[voarsh]

I'm getting
TASK ERROR: storage migration failed: error during cfs-locked 'storage-' operation: unable to create image: got lock timeout - aborting command

However, I don't get this on another NFS shared storage.

I've tried pvecm expected 1.
I need to migrate to this disk.

If I can't I must spend over 37 hours on a MUCH slower NFS shared drive (which is shared from a different node).
This failing to migrate share is actually shared on the same node I am trying to migrate from, I am also able to create LXC's on the same (failing) shared NFS, which is strange.

I get the same thing when adding a disk to the NFS share storage.
update VM 106: -scsi1 FourteenTBExpansionUSB4:150,format=qcow2
TASK ERROR: error during cfs-locked 'storage-FourteenTBExpansionUSB4' operation: unable to create image: got lock timeout - aborting command

Adding a 1 GB disk (I tried 150 GB) is fine though?

update VM 106: -scsi1 FourteenTBExpansionUSB4:1,format=qcow2
