扩容思路：ceph集群容量不足的时候，新加的OSD组成新的pool，制定新的rule规则，新建的bucket都存放在这些新加入的pool里面，注意扩容仅限于新加的bucket，已有的bucket扩容不适用。
###1.新建pool
ceph osd pool create .rgw.buckets.custom 4096 4096 ceph osd pool create .rgw.buckets.custom.index 512 512 ceph osd pool create .rgw.buckets.custom.extra 64 64
###2.调整region和zone配置 导出region配置
radosgw-admin region get --name client.radosgw.us-zone1 > region.conf.json
编辑region.conf.json,修改placement_targets部分
#修改前
"placement_targets": [
{
"name": "default-placement",
"tags": []
}
],
"default_placement": "default-placement" #修改后
"placement_targets": [
{
"name": "default-placement",
"tags": []
},
{
"name": "new",
"tags": []
}
],
"default_placement": "default-placement"导出zone配置
radosgw-admin zone get --name client.radosgw.us-zone1 > zone.conf.json
编辑zone.conf.json,修改placement_targets部分
#修改前
"placement_pools": [
{
"key": "default-placement",
"val": {
"index_pool": ".us-zone1.rgw.buckets.index",
"data_pool": ".us-zone1.rgw.buckets",
"data_extra_pool": ".us-zone1.rgw.buckets.extra"
}
}
] #修改后
"placement_pools": [
{
"key": "default-placement",
"val": {
"index_pool": ".us-zone1.rgw.buckets.index",
"data_pool": ".us-zone1.rgw.buckets",
"data_extra_pool": ".us-zone1.rgw.buckets.extra"
}
},
{
"key": "new",
"val": {
"index_pool": ".rgw.buckets.custom.index",
"data_pool": ".rgw.buckets.custom",
"data_extra_pool": ".rgw.buckets.custom.extra"
}
}导入配置
radosgw-admin region set --name client.radosgw.us-zone1 < region.conf.json radosgw-admin zone set --name client.radosgw.us-zone1 < zone.conf.json
刷新配置信息
radosgw-admin regionmap update --name client.radosgw.us-zone1
注意：所有radosgw服务节点都要进行这一步
/etc/init.d/radosgw restart
###4. 验证测试
测试方法1： 新建bucket需要指定localtion，boto代码如下
from boto.s3.connection import S3Connection import boto access_key = 'xxx' secret_key = 'xxxx' host = 's3.ceph.work' bucket = 'localtest2' conn = S3Connection(access_key, secret_key, host=host, is_secure=False) conn = boto.connect_s3( aws_access_key_id = access_key, aws_secret_access_key = secret_key, host = host, is_secure=False, calling_format = boto.s3.connection.SubdomainCallingFormat(), validate_certs = True, ) bucket = conn.create_bucket(bucket,location=':new') bucket = conn.get_bucket(bucket) print bucket
测试方法2：
s3cmd mb s3://localtest2 --bucket-location=:new
验证
root@ceph.work/# radosgw-admin bucket stats --bucket=localtest2 --name client.radosgw.us-zone1
{
"bucket": "localtest2",
"pool": ".rgw.buckets.custom",
"index_pool": ".rgw.buckets.custom.index",
"id": "us-zone1.477528.2",
"marker": "us-zone1.477528.2",
"owner": "gf",
"ver": "0#1,1#1,2#1,3#1,4#1,5#1,6#1,7#1",
"master_ver": "0#0,1#0,2#0,3#0,4#0,5#0,6#0,7#0",
"mtime": "2016-07-07 15:50:53.000000",
"max_marker": "0#,1#,2#,3#,4#,5#,6#,7#",
"usage": {},
"bucket_quota": {
"enabled": false,
"max_size_kb": -1,
"max_objects": -1
}
