ceph之故障处理1

现象：ceph -s查看集群状态

ceph -s
  cluster:
    id:     1f0490cd-f938-4e20-8ea5-d817d941a6e6
    health: HEALTH_WARN
            application not enabled on 1 pool(s)
            clock skew detected on mon.ceph5
 
  services:
    mon: 3 daemons, quorum ceph4,ceph5,ceph6
    mgr: ceph4(active), standbys: ceph5, ceph6
    osd: 9 osds: 9 up, 9 in
    rgw: 1 daemon active
 
  data:
    pools:   6 pools, 512 pgs
    objects: 253 objects, 24.3MiB
    usage:   9.30GiB used, 34.8GiB / 44.1GiB avail

ceph health detail 
HEALTH_WARN application not enabled on 1 pool(s); clock skew detected on mon.ceph5
POOL_APP_NOT_ENABLED application not enabled on 1 pool(s)
    application not enabled on pool 'images'
    use 'ceph osd pool application enable <pool-name> <app-name>', where <app-name> is 'cephfs', 'rbd', 'rgw', or freeform for custom applications.
MON_CLOCK_SKEW clock skew detected on mon.ceph5
    mon.ceph5 addr 10.1.1.25:6789/0 clock skew 11.2785s > max 2s (latency 0.00214139s)

　　

1.根据提示处理POOL_APP_NOT_ENABLED application not enabled on 1 pool(s)

ceph osd pool application enable images rbd
enabled application 'rbd' on pool 'images'

　　

2.时钟同步下
