Deleting files on CephFS doesn't instantaneously remove the underlying objects because they could still be in use by other clients, and removal takes time proportional to the size of the file. Instead the MDS queues it up to be removed asynchronously. You should see the number of objects counter going down over time. -Greg On Tue, Nov 6, 2012 at 11:21 AM, Denis Fondras <ceph@xxxxxxxxxxx> wrote: > 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.
