<font size=3 face="Arial">I have a reproducible issue where attempting
to delete a file large enough to have been sharded hangs. I can't kill
the 'rm' command and eventually am forced to reboot the client (which in
this case is also part of the gluster cluster). After the node finishes
rebooting I can see that while the file front-end is gone, the back-end
shards are still present.</font>
<br>
<br><font size=3 face="Arial">Is this a known issue? Any way to get around
it?</font>
