Hello Kyle,

>From the ocfs2 code, ocfs2 supports fstrim operation in the cluster environment.
If there was a file system corruption encountered, it should be a bug.
By the way, you should be recommended to run a fstrim operation from one node in the cluster.


> Hello,
> Just opened what I think is a bug with the Ubuntu util-linux package:
> https://bugs.launchpad.net/ubuntu/+source/util-linux/+bug/1681410 
> 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.
