Calculating required number of PGs per pool

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

 



Hi,

I've got 6 OSDs and I want 3 replicas per object, so following the function that's 200 PGs per OSD, which is 1,200 overall.

I've got two RBD pools and the .rgw.buckets pool that are considerably higher in the number of objects it has compared to the others (given that RADOS gateway needs so many pools with very little in them).

How can I get the ratio of PGs to objects to be consistent across all of the pools to avoid the health warnings of:

HEALTH_WARN pool [pool-name] has too few pgs

Best regards
 

Graeme
