Hi,
I enabled pg_autoscaler on a specific pool ssd.
I failed to increase pg_num / pgp_num on pools ssd to 1024:
root@ld3955:~# ceph osd pool autoscale-status
POOL SIZE TARGET SIZE RATE RAW CAPACITY RATIO
TARGET RATIO BIAS PG_NUM NEW PG_NUM AUTOSCALE
cephfs_metadata 395.8
The documentation tell to size the DB to 4% of the disk data ie 240GB
for a 6 TB disk. Plz gives more explanations when your answer disagree
with the documentation !
