Ok, actually, the problem was somebody writing to the filesystem. So I
moved their files and got to 0 objects. But then I tried to remove the
original data pool and got an error:
# ceph fs rm_data_pool cephfs cephfs-data
Error EINVAL: cannot remove default data pool
So it seems I will neve
This was after a while (I did notice that the number of objects went
higher before it went lower). It is actually reporting more objects now.
I'm not sure if some co-worker or program is writing to the
filesystem... It got to these numbers and hasn't changed for the past
couple hours.
# ceph
Afaik MDS doesn't delete the objects immediately but defer it for later. If
you check that again now, how many objects does it report?

I copied the data to a new directory and then removed the data from the
old directory, but df still reports some objects in the old pool (not
zero). Is there

Given that the MDS knows everything, it seems trivial to add a ceph 'mv'
command to do this. I looked at using tiering to try and do the move,

the ceph
guys implement a mv that does what you expect from it. Now it acts more
or less like a linking.

Are you talking about adding the new data pool to the current
filesystem? Like:
$ ceph fs add_data_pool my_ceph_fs new_ec_pool
I have done that, and now the filesystem shows up as having two data pools:
$ ceph fs ls
name: my_ceph_fs, metadata pool: cephfs_meta, data pools:
[cephfs_data
What about adding the new data pool, mounting it and then moving the
files? (read copy because move between data pools does not what you
expect it do)
