And I noticed that there are some packets send between each node periodically

I frequently find that I'm unable to umount volumes, even after lsof

John,
This is a cluster managed mount so there is no fstab entry.
The lsof options you show...
"vgs -o vg_name,vg_tags"
are a welcome addition to my tool belt, thanks for that.

I am out today but I'll try these tomorrow.

Are you sure that you're specifying the filesystem mount point (as
listed in fstab) and not the directory. I
