Some further bits of info on this. I've found a lot of similar issues related to linking, but I don't seem to have any of those same issues.</div>

I did notice that the gfid is present in the `.remove_me` directory, though the file itself is not removed still. Perhaps this is the root of the problem? I don't know much about the `.remove_me` dir, and couldn't find similar issues though.</div>

The error is consistent and reproducible. Every time I remount and try and delete the client crashes again. I'm assuming something is wrong with the shards. How do I correct this, or is this a bug with sharding?<br>
