Ceph radosgw: ERROR: endpoints not configured for upstream zone, meta sync: ERROR: failed to fetch mdlog info

The s3cmd client was getting error code 500 for bucket creation.

rgw logs were showing following errors:

2018-06-06 18:57:01.808147 7f0114b8d700  0 ERROR: endpoints not configured for upstream zone
2018-06-06 18:57:01.808164 7f0114b8d700  0 meta sync: ERROR: failed to fetch mdlog info
2018-06-06 18:57:31.808298 7f0114b8d700  0 ERROR: endpoints not configured for upstream zone
2018-06-06 18:57:31.808326 7f0114b8d700  0 meta sync: ERROR: failed to fetch mdlog info

This problem can occur with an improperly configured zone.

Solution

In my case I resolved it by running the following commands:
 
$ radosgw-admin zone modify --rgw_realm=my_realm --rgw-zonegroup=in --rgw-zone=north --master --default

$ radosgw-admin period update

$ radosgw-admin period commit
