ceph命令总结
一、集群
1、启动一个ceph 进程
2、查看机器的监控状态[查看集群健康状态细节]
c

1、查看ceph集群中的pool数量
c
# ceph osd lspools输出结果：
c
1 images,2 volumes,3 backups,4 vms,5 k8s,6 .rgw.root,7 cephfs_data,8 cephfs_metadata,9 default.rgw.control,10 default.rgw.meta,11 default.rgw.log,2、在ceph集群中创建一个pool
c
ceph osd pool create jiayuan 100 #这里的100指的是PG组3、为一个ceph pool配置配额
c
ceph osd pool set-quota data max_objects 100004、在集群中删除一个pool
c
ceph osd pool delete testpool testpool --yes-i-really-really-mean-it #集群名字需要重复两次备注：删除pool需要在配置文件ceph.conf中 [mon]添加mon allow pool delete = true并重启mon服务, 如systemctl restart ceph-mon.target
5、显示集群中pool的详细信息
c
# rados df8、查看data池的pg数量
c
# ceph osd pool get volumes pg_num输出信息：
c
pg_num: 169、设置data池的最大存储空间为100T（默认是1T)
ceph osd pool set data target_max_bytes 100000000000000
10、设置data池的副本数是1
c
ceph osd pool set jiayuan size 111、设置data池能接受写操作的最小副本为1
c
ceph osd pool set jiayuan min_size 112、查看集群中所有pool的副本尺寸
c
ceph osd dump | grep 'replicated size'13、设置一个pool的pg数量
c
ceph osd pool set jiayuan pg_num 12814、设置一个pool的pgp数量
c
ceph osd pool set jiayuan pgp_num 12815、查询public与cluster是否分开，在存储节点执行以下命令：
c
ps aux | grep osd输出信息：
