Hi Konstantin,
the number PG's for the metadata pool now is 16.
The number PG's for the data pool now is 512.
I removed the backward-compatible weight-set.
But now:
$ ceph osd getmap -o om ; osdmaptool om --upmap upmap.sh --upmap-pool=cephfs_data --upmap-deviation=0
got osdmap epoch 94013
osdmaptool: osdmap file 'om'
writing upmap command output to: upmap.sh
checking for upmap cleanups
upmap, max-count 100, max deviation 0
limiting to pools cephfs_data (1)
no upmaps proposed
and
$ ceph osd df class hdd
[…]
MIN/MAX VAR: 0.80/1.20 STDDEV: 6.45
There seems to be a bug in nautilus.
I think about increasing the number of PG's for the data pool again, because the average number of PG's per OSD now is 76.8.
What do you say?
Thanks,
Lars
