Hi,
I was doing some tests with rados bench on a Erasure Coded pool (using
keyvaluestore-dev objectstore) on 0.83, and I see some strangs things:
[root@ceph001 ~]# ceph status
cluster 82766e04-585b-49a6-a0ac-c13d9ffd0a7d
health HEALTH_WARN too few pgs per osd (4 < min 20)

ceph001,ceph002,ceph003
mdsmap e116: 1/1/1 up {0=ceph001.cubone.os=up:active}, 2 up:standby
osdmap e292: 78 osds: 78 up, 78 in
pgmap v48873: 320 pgs, 4 pools, 15366 GB data, 3841 kobjects
1381 GB used, 129 TB / 131 TB avail
320 active+clean
There is around 15T of data, but only 1.3 T usage.
This is also visible in rados:

Another (related?) thing: if I do rados -p ecdata ls, I trigger osd
shutdowns (each time):
I get a list followed by an error:
