You'll need to restart the mds/mdt machine before the space will
reclaim off the OST.<br>

<div>I am still learning Lustre and I have run into an issue. I
have referred to both the Lustre admin manual and Google, but
I've had no luck in finding the answer. We are using Lustre
2.8.0.</div>

<div>We had an OST fill due to a single large file. I took the
OST offline via the lctl deactivate command to prevent new
files from being created on the OST. While the OST was
deactivated, the user deleted the file. Now it appears the
metadata is gone from the MDS (which makes sense), but the
data chunks on the OST remain even after I reactivated the
OST.</div>

<div>I believe that running lfsck would resolve this issue, but
I am not sure if I should run it on the MDS or the OST? If
this is the fix, what options would I need to use?</div>
