lvremove -> Logical volume ..... is used by another device.

[l.ansaloni]

Hi,
I try to remove unused lvm:

# lvremove -f /dev/volssd-vg/vm-520-disk-2
  Logical volume volssd-vg/vm-520-disk-2 is used by another device.

same result with the command:

# lvchange -a n /dev/volssd-vg/vm-520-disk-2
  Logical volume volssd-vg/vm-520-disk-2 is used by another device.

I try to figure out which process block the resource:

# lsof /dev/volssd-vg/vm-520-disk-2
(is empty)

The cluster consist of 6 server, I try the command above on all the server with the same result.

I also remove the link in /dev/mapper

# pveversion
pve-manager/4.3-10/7230e60f (running kernel: 4.4.21-1-pve)

Could someone help me?
Thank you,
Lorenzo
