Hi Francois,<br>
<br>
We had something similar a few months back - I suspect a bug somewhere.<br>
<br>
Basically files weren't getting removed from the OST. Eventually, we mounted as ext, and removed them manually, I think.<br>
<br>
A reboot of the file system meant that rm operations then proceeded correctly after that.<br>
<br>
Cheers,<br>
Alastair.<br>

leaked). If there are a lot of files this may take some time, rebooting will not speed it up.<br>
