Re: Num of PGs

Hi,

I'm curious what would be the official recommendation for when you
have multiple pools.
In total we have 21 pools and that lead to around 12000 PGs for only 24 OSDs.

The 'data' and 'metadata' pools are actually unused, and then we have
9 pools of 'rgw' meta data ( .rgw, .rgw.control, .users.uid,
.users.email, .users, .log, .usage, .intent-log, .rgw.gc ). Then we
have 2 pools of RBD volumes and 8 pools assigned to RGW buckets. We
splitted those so we could control placement and replication level.
(The OSDs are split into 'bulk' on SATA drives and 'fast' on SAS 10k
drives).

Cheers,

    Sylvain
