Re: increase pg num

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.

 

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.

 

Thanks,

 

Jacob

Subject: [ceph-users] increase pg num

 

Hello, 

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
