Hi,
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/
returns nothing.
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.
Cheers,
Alastair.
