>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.
> 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.
