[lustre-discuss] Full OST

We have a file system where each OST is a single SSD.
One of those is reporting as 100% full (lfs df -h /snap8):
snap8-OST004d_UUID 5.8T 2.0T 3.5T 37% /snap8[OST:77]
snap8-OST004e_UUID 5.8T 5.5T 7.5G 100% /snap8[OST:78]
snap8-OST004f_UUID 5.8T 2.0T 3.4T 38% /snap8[OST:79]
However, I can't find any files on it:
lfs find --ost snap8-OST004e /snap8/
I guess that it has filled up, and that there is some bug or other that is
now preventing proper behaviour - but I could be wrong.
Does anyone have any suggestions?
Essentially, I'd like to find some of the files and delete or migrate
some, and thus return it to useful production.
