Comment 3 for bug 1681410

It is one device.

We have 2 luns for 2 different ocfs2 filesystems mounted on all servers (6) in the cluster. It is presented via fiber channel from our SAN.

I think the issue is that if you run fstrim from all servers which are mounting the same ocfs2 filesystem at the same time, bad stuff happens.

We are using multipth:
