Ceph » rgw

On radosgw node I have custom rgw_* parameters

$ more ceph.conf
...
[client.rgw.rCeph-gw-1]
rgw_frontends = "civetweb port=80" 
rgw_dns_name = s3.amazonaws.com
rgw_gc_obj_min_wait = 60
rgw_gc_processor_max_time = 45
rgw_gc_processor_period = 45
debug_rgw = 10

1. Start RGW service

systemctl start ceph-radosgw@rgw.rCeph-gw-1.service

2. Create bucket via s3cmd

$ s3cmd mb s3://testing1
$ s3cmd mb s3://testing2
$ s3cmd mb s3://testing3

3. List metadata of bucket & bucket.instance

$ radosgw-admin metadata list bucket.instance|sort
[
    "testing1:d07687d2-d90c-46de-aa52-950ff7f03463.1455699.1",
    "testing2:d07687d2-d90c-46de-aa52-950ff7f03463.1455699.2",
    "testing3:d07687d2-d90c-46de-aa52-950ff7f03463.1455699.3" 
]

$ radosgw-admin metadata list bucket
[
    "testing1",
    "testing2",
    "testing3" 
]

4. Restart RGW service

systemctl restart ceph-radosgw@rgw.rCeph-gw-1.service

5. Create another bucket

$ radosgw-admin metadata list bucket.instance|sort
[
    "testing1:d07687d2-d90c-46de-aa52-950ff7f03463.1455699.1",
    "testing2:d07687d2-d90c-46de-aa52-950ff7f03463.1455699.2",
    "testing3:d07687d2-d90c-46de-aa52-950ff7f03463.1455699.3",
    "testing4:d07687d2-d90c-46de-aa52-950ff7f03463.1455717.1"  -> new bucket with different masking id
]

$ radosgw-admin metadata list bucket
[
    "testing1",
    "testing2",
    "testing3",
    "testing4" 
]

6. Remove bucket & check metadata bucket.instance

$ s3cmd rb s3://testing1
$ s3cmd rb s3://testing2
$ s3cmd rb s3://testing3
$ s3cmd rb s3://testing4

$ radosgw-admin metadata list bucket.instance|sort
[
    "testing1:d07687d2-d90c-46de-aa52-950ff7f03463.1455699.1",
    "testing2:d07687d2-d90c-46de-aa52-950ff7f03463.1455699.2",
    "testing3:d07687d2-d90c-46de-aa52-950ff7f03463.1455699.3",
    "testing4:d07687d2-d90c-46de-aa52-950ff7f03463.1455717.1" 
]

$ radosgw-admin metadata list bucket
[]
