4.3. Verifying Ceph cluster status

Complete the following steps to verify Ceph cluster status.

Procedure

  1. Log in to the active Controller node.
  2. Enter the following command:

    $ sudo ceph -s
    
    cluster:
        id: 3369e280-7578-11e8-8ef3-801844eeec7c
        health: HEALTH_OK
    
      services:
        mon: 3 daemons, quorum overcloud-controller-1,overcloud-controller-2,overcloud-controller-0
        mgr: overcloud-controller-1(active), standbys: overcloud-controller-2, overcloud-controller-0
        mds: cephfs-1/1/1 up  {0=overcloud-controller-0=up:active}, 2 up:standby
        osd: 6 osds: 6 up, 6 in

    There is one active MDS and two MDSs on standby.

  3. To check the status of the Ceph file system in more detail, enter the following command and replace <cephfs> with the name of the Ceph file system:

    $ sudo ceph fs ls
    
    name: cephfs, metadata pool: manila_metadata, data pools: [manila_data]
