Ceph故障排除: 1 pool(s) do not have an application enabled

1. 现象

执行ceph -s时有报错:1 pool(s) do not have an application enabled

root@ceph-mgr01:/apps# ceph -s
  cluster:
    id:     86c42734-37fc-4091-b543-be6ff23e5134
    health: HEALTH_WARN
            1 pool(s) do not have an application enabled
 
  services:
    mon: 3 daemons, quorum ceph-mon01,ceph-mon02,ceph-mon03 (age 4h)
    mgr: ceph-mgr01(active, since 84m)
    mds: 2/2 daemons up, 2 standby
    osd: 16 osds: 16 up (since 4h), 16 in (since 5d)
    rgw: 2 daemons active (2 hosts, 1 zones)
 
  data:
    volumes: 1/1 healthy
    pools:   10 pools, 273 pgs
    objects: 1.13k objects, 17 MiB

2. 故障排除

由于ceph -s报错内容不是很明确,只是说了有个pool 没有启用应用,
运行 ceph health detail 查看报错详情

# ceph health detail 
HEALTH_WARN 1 pool(s) do not have an application enabled
[WRN] POOL_APP_NOT_ENABLED: 1 pool(s) do not have an application enabled
    application not enabled on pool 'mypool'
    use 'ceph osd pool application enable <pool-name> <app-name>', where <app-name> is 'cephfs', 'rbd', 'rgw', or freeform for custom applications.

报错信息是mypool没有指定应用类型,应用类型可以是3个中的任意一个那么这里就把它作为cephfs

ceph osd pool application enable mypool cephfs
enabled application 'cephfs' on pool 'mypool'

再次查看ceph状态

root@ceph-mgr01:/apps# ceph health detail 
HEALTH_OK
root@ceph-mgr01:/apps# ceph -s
  cluster:
    id:     86c42734-37fc-4091-b543-be6ff23e5134
    health: HEALTH_OK
 
  services:
    mon: 3 daemons, quorum ceph-mon01,ceph-mon02,ceph-mon03 (age 4h)
    mgr: ceph-mgr01(active, since 95m)
    mds: 2/2 daemons up, 2 standby
    osd: 16 osds: 16 up (since 4h), 16 in (since 5d)
    rgw: 2 daemons active (2 hosts, 1 zones)
 
  data:
    volumes: 1/1 healthy
    pools:   10 pools, 273 pgs
    objects: 1.13k objects, 17 MiB
