Hi Kshitij, When you say you are running 'mount -o discard' is that against the local file system that mounts the SSD block device on the servers or the pvfs2 mount on the client? Based on your mention of SSD I believe you'll want to mount the local file system on the server with those options.
>From the client mount perspective we don't support the discard option. If this is what you're interested in could you explain the use case or what the expected behavior of that functionality would be?
