如何修改bucket index shards
root@CVM01:~# radosgw-admin zonegroup get > tmp.conf
{
"id": "0a4d68f0-0a16-4e0c-a88b-d0b708ce75f1",
"name": "default",
"api_name": "",
"is_master": "true",
"endpoints": [],
"hostnames": [],
"hostnames_s3website": [],
"master_zone": "7240a9f2-42ea-4f3d-b534-ad4d867ab9cb",
"zones": [
{
"id": "7240a9f2-42ea-4f3d-b534-ad4d867ab9cb",
"name": "default",
"endpoints": [],
"log_meta": "false",
"log_data": "false",
"bucket_index_max_shards": 0,
"read_only": "false",
"tier_type": "",
"sync_from_all": "true",
"sync_from": []
}
],
"placement_targets": [
{
"name": "default-placement",
"tags": []
}
],
"default_placement": "default-placement",
"realm_id": ""
}
修改 bucket_index_max_shards = 64 之后，然后执行：
radosgw-admin region set < tmp.conf
