This article will explain in detail for you and then use bucket localtion to achieve rgw cluster expansion, the content of the article is of high quality, so the editor will share it with you for reference. I hope you will have a certain understanding of the relevant knowledge after reading this article.

Idea of capacity expansion: when the capacity of the ceph cluster is insufficient, the newly added OSD forms a new pool, formulates new rule rules, and the newly built bucket is stored in these newly added pool. Note that the expansion is limited to the newly added bucket, and the existing bucket expansion is not applicable.

# 1. Create a new pool

Ceph osd pool create .rgw.buckets.custom 4096 4096ceph osd pool create .rgw.buckets.custom.index 512 512ceph osd pool create .rgw.buckets.custom.extra 64 64

# 2. Adjust region and zone configuration export region configuration

Radosgw-admin region get-- name client.radosgw.us-zone1 > region.conf.json

Edit the region.conf.json and modify the placement_targets section

# before modification, "placement_targets": [{"name": "default-placement", "tags": []}], "default_placement": "default-placement" # modified "placement_targets": [{"name": "default-placement", "tags": []} {"name": "new", "tags": []}], "default_placement": "default-placement"

Export zone configuration

Radosgw-admin zone get-- name client.radosgw.us-zone1 > zone.conf.json

Edit the zone.conf.json and modify the placement_targets section

# "placement_pools" before modification: [{"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"}] # modified "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.custom"}}

Import configuration

Radosgw-admin region set-- name client.radosgw.us-zone1 < region.conf.jsonradosgw-admin zone set-- name client.radosgw.us-zone1 < zone.conf.json

Refresh configuration information

Radosgw-admin regionmap update-- name client.radosgw.us-zone13. Restart the service

Note: all radosgw service nodes need to do this step

/ etc/init.d/radosgw restart

# 4. Verification test

Test method 1: the new bucket needs to specify the following localtion,boto code

From boto.s3.connection import S3Connectionimport botoaccess_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

Test method 2:

S3cmd mb s3://localtest2-bucket-location=:new

Verification

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": "master_ver": "0,0,0,0,1magicles, 2pyrrons, 3magicles,"master_ver": "0primes, 1memorials, 5magicles, 5magicles,"master_ver": "0perpendiculum, 1meme, 3pence, 5pyrrons, 5pommies, 5pommies", "mtime": "2016-07-07 15 usage 50, 53.000000", "max_marker": "0,000,000,000," "bucket_quota": {"enabled": false, "max_size_kb":-1, "max_objects":-1}} about then using bucket localtion to achieve rgw cluster expansion, that's all.
