查看,检查,修复pg的命令

标签(空格分隔): ceph,ceph运维,pg


如果集群状态是HEALTH_ERR 并且有pgs inconsistent,需要进行如下操作:

1. 通过下面的命令查看哪些pg状态不一致:

# ceph pg dump|grep inconsistent

2. 根据输出的pg id(如:1.23)进行一致性检查:

[root@node3 ~]# ceph pg scrub 1.23
instructing pg 1.23 on osd.5 to scrub

或者,进行深度的一致性检查:

[root@node3 ~]# ceph pg deep-scrub 1.23
instructing pg 1.23 on osd.5 to deep-scrub

3. 最后修复该pg:

[root@node3 ~]# ceph pg repair 1.23
instructing pg 1.23 on osd.5 to repair

把所有不一致的pg修复完成后,最后确认集群状态

4. 确认集群状态:

[root@node3 ~]# ceph -s
  cluster:
    id:     b8b4aa68-d825-43e9-a60a-781c92fec20e
    health: HEALTH_OK
 
  services:
    mon: 1 daemons, quorum node1
    mgr: node1(active)
    osd: 6 osds: 6 up, 6 in
 
  data:
    pools:   1 pools, 64 pgs
    objects: 0 objects, 0 bytes
    usage:   6368 MB used, 55071 MB / 61440 MB avail
    pgs:     64 active+clean
