Ceph 创建/删除存储池、设置存储池副本数

1、设置存储池副本数

$ ceph osd pool get cephrbd size
$ ceph osd pool set cephrbd size 3

2. 打印存储池列表

    $ ceph osd lspools

3、创建 删除存储池

创建pool
$ ceph osd pool create testPool 64

重命名pool
$ ceph osd pool rename testPool amizPool

获取pool 副本数
$ ceph osd pool get amizPool size
设置pool 副本数
$ ceph osd pool set amizPool size 3

获取pool pg_num/pgp_num
$ ceph osd pool get amizPool pg_num
$ ceph osd pool get amizPool pgp_num
设置pool pg_num/pgp_num
$ ceph osd pool set amizPool pg_num 128
$ ceph osd pool set amizPool pgp_num 128

删除存储池
$ ceph osd pool delete  amizPool  amizPool --yes-i-really-really-mean-it  

删除池提示错误
Error EBUSY: pool 'testpool' is in use by CephFS 
$ ceph mds remove_data_pool testpool
$ ceph osd pool delete testpool testpool  --yes-i-really-really-mean-it

4、设置查看存储池pool配额

查看存储池pool 配额
# ceph osd pool get-quota poolroom1
    quotas for pool 'poolroom1':
      max objects: N/A
      max bytes  : 6144MB   # 存储池pool配额 6G
