Dear all
After upgrading to Pacific, we are now getting health warnings from the
auto scaler:
10 pools have too few placement groups
8 pools have too many placement groups
The thing is, I do not particularly care about the recommendations from
the auto scaler. So I checked and saw that it was set to warning on all
pools:
| ceph osd pool autoscale-status
POOL SIZE TARGET SIZE RATE RAW CAPACITY RATIO TARGET RATIO EFFECTIVE RATIO BIAS PG_NUM NEW PG_NUM AUTOSCALE BULK
openstack-glance 902.7G 3.0 618.2T 0.0043 1.0 128 warn False
openstack-cinder 99.48T 3.0 618.2T 0.4827 1.0 2048 warn False
openstack-nova 169.6G 3.0 618.2T 0.0008 1.0 128 warn False
[...]
No worries, I just turn it off:
| ceph osd pool set noautoscale
Check it's off:
| ceph osd pool autoscale-status
POOL SIZE TARGET SIZE RATE RAW CAPACITY RATIO TARGET RATIO EFFECTIVE RATIO BIAS PG_NUM NEW PG_NUM AUTOSCALE BULK
openstack-glance 902.7G 3.0 618.2T 0.0043 1.0 128 off False
openstack-cinder 99.48T 3.0 618.2T 0.4827 1.0 2048 off False
openstack-nova 169.6G 3.0 618.2T 0.0008 1.0 128 off False
[...]
That looks as expected. But despite that, I'm still getting the health
warnings:
| ceph --status
[...]
10 pools have too few placement groups
8 pools have too many placement groups
So how can I get rid of the warnings (without changing the number of PGs
on my pools!)?
Sincerely
Niklaus Hofer
