Setting a zone group map

Setting a zone group map consists of creating a JSON object consisting of one or more zone groups, and setting the master_zonegroup for the cluster. Each zone group in the zone group map consists of a key/value pair, where the key setting is equivalent to the name setting for an individual zone group configuration, and the val is a JSON object consisting of an individual zone group configuration.

You may only have one zone group with is_master equal to true, and it must be specified as the master_zonegroup at the end of the zone group map. The following JSON object is an example of a default zone group map.

    "zonegroups": [
        {

To set a zone group map, run the following command:

Example

[ceph: root@host01 /]# radosgw-admin zonegroup-map set --infile zonegroupmap.json

Where zonegroupmap.json is the JSON file you created. Ensure that you have zones created for the ones specified in the zone group map. Finally, update the period.

Example

[ceph: root@host01 /]#  radosgw-admin period update --commit
