Hi Von
This is incorrect ceph conf setting for openstack.
http://tkannadhasan.blogspot.com/2018/04/ceph-pool-rbd-has-many-more-objects-per.html
https://bugs.launchpad.net/charm-ceph-mon/+bug/1804846
1, you can google to find ceph command to update this config item, "mon pg warn max object skew"
2, Or submit a launchpad issue, maybe we should update ceph config item, to change puppet setting in starlingx for ceph.
BR!

Hello all,
We are installed Openstack on StarlingX ( It's containing EdgeX, k8s and Openstack ). After that, The VM size incresed to 145 GB. We converted to
Qcow2 images and the size is 45 GB and after that, compression also, Its getting around 13 GB. So, upload and transferring is bit of tough. So, Is there any way to reduce the VM size / performing some cleanup operations. So that, The VM size is decreased something.
If any one aware on this issue, Please let us know. It's a great help.

Thanks & Regards

hi,
my ceph have an health warning:
[sysadmin at controller-0 ~(keystone_admin)]$ ceph -s
cluster:
id: 2d6cb518-420e-4a97-919a-f42b808f2049
health: HEALTH_WARN
2 pools have many more objects per pg than average
services:
mon: 3 daemons, quorum controller-0,controller-1,storage-0
mgr: controller-0(active), standbys: controller-1
osd: 30 osds: 30 up, 30 in
data:
pools: 5 pools, 600 pgs
objects: 97.12 k objects, 596 GiB
usage: 1.7 TiB used, 107 TiB / 109 TiB avail
pgs: 600 active+clean
io:
client: 25 MiB/s rd, 36 MiB/s wr, 169 op/s rd, 104 op/s wr
after checkout "ceph df", i can see an huge number of objects:
[sysadmin at controller-0 ~(keystone_admin)]$ ceph df
GLOBAL:
SIZE AVAIL RAW USED %RAW USED
109 TiB 107 TiB 1.7 TiB 1.58
POOLS:
NAME ID USED %USED MAX AVAIL OBJECTS
kube-rbd 1 1.5 GiB 0 33 TiB 451
images 2 437 GiB 1.28 33 TiB 55950
cinder.backups 3 0 B 0 33 TiB 0
cinder-volumes 4 151 GiB 0.45 33 TiB 39780
ephemeral 5 0 B 0 33 TiB 0
is this a normal value for round about 12 images and 8 values ? maybe there is some thrash inside this pools, how can i run an cleanup?
greez & thx,
volker.
