The default CRUSH placement rules want to put replica pgs on different
hosts - so with pools of size 3 you need at least 3 hosts.
You can get around this by editing your CRUSH rules to put replica pgs
on different OSDs instead - but clearly redundancy is impacted in that
case - best to have (n
Thank you soo much! That seems to work immidetately.
ATM I still see 3 pgs in active+clean+scrubbing state - but that will
hopefully fix by time.
So the way to go with firefly, is to either use at least 3 hosts for
OSDs - or reduce the number of replicas?
Kind Regards,

Hi,
I experienced exactly the same with 14.04 and the 0.79 release.
It was a fresh clean install with default crushmap and ceph-deploy install
as pr. the quick-start guide.
Oddly enough changing replica size (incl min_size) from 3 - 2 (and 2->1)
and back again it worked.
I didn't have time to l
Right,
I've run into the situation where the system seems reluctant to
reorganise after changing all the pool sizes - until the osds are
restarted (essentially I just rebooted each host in turn) *then* the
health went to OK. This was a while ago (pre 0.72), so something else
may be going on w
Hello,
I've already thought about that - but even after changing the
replication level (size) I'm not getting a clean cluster (there are only
the default pools ATM):
root@ceph-m-02:~#ceph -s
cluster b04fc583-9e71-48b7-a741-92f4dff4cfef
health HEALTH_WARN 232 pgs stuck unclean; recove
So that's two hosts - if this is a new cluster chances are the pools
have replication size=3, and won't place replica pgs on the same host...
'ceph osd dump' will let you know if this is the case. If it is ether
reduce size to 2, add another host or edit your crush rules to allow
replica pgs on
#ceph osd tree
# idweight type name up/down reweight

-2 32.72 host ceph-s-01

1 7.27osd.1 up 1
2 9.09osd.2 up 1
3 9.09
What does `ceph osd tree` output?
