Default question: have you tried to fail the mgr? ;-) ceph mgr fail Zitat von Niklaus Hofer <niklaus.hofer@stepping-stone.ch>:
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
