1.1介紹
RADOS全稱Reliable Autonomic Distributed Object Store，是Ceph集群的精華，用戶實現(xiàn)數(shù)據(jù)分配、Failover等集群操作。
2. 常用操作
2.1 查看集群多少個pool
$ rados lspools
rbd
test_data
test_metadata
test
benmark_test
.rgw.root
default.rgw.control
default.rgw.meta
default.rgw.log
default.rgw.buckets.index
web-services
test_pool
cephfs_data
cephfs_metadata
test_lihang

2.3 創(chuàng)建pool
$ rados mkpool test_lihang1
successfully created pool test_lihang1
2.4 查看pool中object對象
$ rados ls -p test_data | more
10000026de5.00000000
1000005f1f3.00000000
100000664db.00000000

2.5 創(chuàng)建一個對象object
$ rados create test-object -p test_data
$ rados -p test_data ls
2.6 刪除一個對象object
$ rados rm test-object -p test_data
