[ClusterLabs] PSA Ubuntu 16.04 and OCSF2 corruption

Just opened what I think is a bug with the Ubuntu util-linux package:



The 'fstrim' command is run weekly on all filesystems.  If you're using ocfs2 and the same filesystem is mounted on multiple Ubuntu 16.04 servers, this fstrim is run at the same time to the same device from all servers.  I'm positive this is what's causing my filesystem corruption issues, which occurs a minute or two after fstrim is scheduled to run.
