Re: At what point are objects removed?

[Gregory Farnum <gfarnum@xxxxxxxxxx>]

 CephFS files are deleted asynchronously by the mds once there are no more client references to the file (NOT when the file is unlinked -- that's not how posix works). If the number of objects isn't going down after a while, restarting your samba instance will probably do the trick.

Hi, may be I got something wrong or did not understend it yet in total.

I have some pools and created some test rbd images which are mounted to
a samba server.

After the test I deleted all files from the on the samba server.

But "ceph df detail" and "ceph -s" show still used space.

The OSDs on the ceph osd nodes are also filled with data.

My question: At what point will the still existing but not needed/used
objects be removed?
