Subject: Cleaning up CephFS pool
Date: Tue, 06 Nov 2012 20:21:03 +0100	[thread overview]
Message-ID: <5099631F.6090802@ledeuns.net> (raw)

Hello all,

I noticed that removing files on CephFS doesn't reclaim free space using 
ceph version 0.52(commit:e48859474c4944d4ff201ddc9f5fd400e8898173)

I created 2 500GB files on CephFS (mounted with ceph-fuse) and then 
removed them. Now "rados df -p data" shows a 1GB usage :
--8<----------------
pool name       category                 KB      objects       clones 
   degraded      unfound           rd        rd KB           wr        wr KB
data            -                 1048580595       257696            0 
           0           0            0            0       628853   1629192870
--8<----------------

Is there a way to clean it up ? "rados cleanup" needs a prefix I don't 
know...
Of course, I could "rm" every objects but what if I had other files that 
I don't want to remove from CephFS ?

Thanks in advance,
Denis
