Pools

Calculate a suitable number of placement groups for the pools the radosgw daemon will create. Set the calculated values as defaults in the Ceph configuration database.

Use the Ceph Placement Group’s per Pool Calculator to calculate a suitable number of placement groups for the pools the radosgw daemon will create.

For example,

[ceph: root@host01 /]#  ceph config set osd osd_pool_default_pg_num = 32
[ceph: root@host01 /]#  ceph config set osd osd_pool_default_pgp_num = 32

Note: Making this change to the Ceph configuration will use those defaults when the Ceph Object Gateway instance creates the pools. Alternatively, you can create the pools manually.

Pool names particular to a zone follow the naming convention ZONE_NAME.POOL_NAME. For example, a zone named us-east will have the following pools:

.rgw.root
us-east.rgw.control
us-east.rgw.meta
us-east.rgw.log
us-east.rgw.buckets.index
us-east.rgw.buckets.data
us-east.rgw.buckets.non-ec
us-east.rgw.meta:users.keys
us-east.rgw.meta:users.email
us-east.rgw.meta:users.swift
us-east.rgw.meta:users.uid
