Hi All,
We have added the ceph object storage meters to openstack ceilometer.
Here is the openstack doc update:

Hi ,
I was going through this simplified crush algorithm given in ceph website.
def crush(pg):
all_osds = ['osd.0', 'osd.1', 'osd.2', ...]
result = []
# size is the number of copies; primary+replicas
while len(result) < size:
--> *r = hash(pg)*
chosen = all_osds[ r % len(all
When you reformat the drive, it generates a new UUID so to Ceph it is as if
it was a brand new drive. This does seem heavy handed, but ceph was
designed for things to fail and it is not unusual to do things this way.
Ceph is not RAID so you usually have to do some unthinking.
You could probably ke

I have been experimenting with Ceph, and have some OSDs with drives
containing XFS filesystems which I want to change to BTRFS.
(I started with BTRFS, then started again from scratch with XFS
[currently recommended] in order to eleminate that as a potential cause
of some issues, now with further ex
