Description

I create all EC pools to begin a multisite configuration in Jewel 10.2.3 on CentOS 7

[default]
rgw_realm_root_pool = gold.rgw.root
rgw_zonegroup_root_pool = gold.rgw.root
rgw_zone_root_pool = gold.rgw.root
rgw_period_root_pool = gold.rgw.root

[client.rgw.cephrgw]
rgw_zone = us-east
rgw_frontends = "civetweb port=80"
host = cephrgw

ceph osd pool create <pool-name> 8 8 erasure

gold.rgw.root
us-east.rgw.control
us-east.rgw.data.root
us-east.rgw.gc
us-east.rgw.log
us-east.rgw.users.uid
us-east.rgw.users.keys
us-east.rgw.meta
us-east.rgw.buckets.index
us-east.rgw.buckets.data

ceph osd pool get gold.rgw.root crush_ruleset
crush_ruleset: 1

1. realm, zonegroup, zone are created successfully
2. Cannot create system user

radosgw-admin user create --uid=zone.user --display-name 'Zone User' --system --access-key=$SYSTEM_ACCESS_KEY --secret=$SYSTEM_SECRET_KEY

could not create user: unable to create user, unable to store user info

This process works if the pools are replicated pools

1. If us-east.rgw.log pool is replicated then system user can be created

2. us-east.rgw.buckets.index us-east.rgw.buckets.data must also be replicated otherwise all bucket operations (s3cmd) fail

rgw cannot use ec pool for metadata as it lacks some of the functionality that it requires. Please open a doc bug if you think docs are wrong. Thanks!
