I am not sure about v0.80.6-1 but in v0.80.7 the --allow-experimental-feature option is not required. I have increased pg_num and pgp_num in v0.80.7 without any issues.
on how big cluster, how long did it take to recovery from this change?
It may be safer to make the change incrementally rather than all at once. Since v0.72, ceph does not allow extreme changes in pg_num sizes.
It make sense, thanks.
Thanks,

Subject: increase pg numHello,
I'm running debian 8 with ceph 0.80.6-1 firefly in production and I need to double the count of pgs. I've found that it was experimantal feature, is it safe now?
Is there still --allow-experimental-feature switch for ceph osd pool set {pool-name} pg_num {pg_num} command ?Thanks
