防止集群数据恢复设置

---

有些场景下，对osd进行一些操作，但是并不想要集群进行数据恢复，此时，可以通过设置noout标志来实现：

[root@node3 ~]# ceph osd set noout
noout is set
[root@node3 ~]# ceph -s
  cluster:
    id:     b8b4aa68-d825-43e9-a60a-781c92fec20e
    health: HEALTH_WARN
            noout flag(s) set
 
  services:
    mon: 1 daemons, quorum node1
    mgr: node1(active)
    osd: 6 osds: 6 up, 6 in
         flags noout
 
  data:
    pools:   0 pools, 0 pgs
    objects: 0 objects, 0 bytes
    usage:   6339 MB used, 55100 MB / 61440 MB avail
    pgs:     

去除noout标志命令：

[root@node3 ~]# ceph osd unset noout
noout is unset
[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:   0 pools, 0 pgs
    objects: 0 objects, 0 bytes
    usage:   6339 MB used, 55100 MB / 61440 MB avail
    pgs:
