Ceph: Global Recovery Event running despite Health OK

Issue

• Global Recovery Event running despite Health OK
• Global Recovery Event never completes
• Global Recovery Event running endlessly
• In RHCS 4.x, the Progress Module can negatively affect the Ceph MON Services and in some case cause impact to production.

Example, nothing is wrong, but a Global Recovery Event is running:

$ ceph -s
  cluster:
    id:     bxxxyyy2-bxxd-4yy3-8xxb-fyyyxxxyyye6
    health: HEALTH_OK

  services:
    mon: 3 daemons, quorum a,c,d (age 2w)

    osd: 3 osds: 3 up (since 2h), 3 in (since 2w)
    rgw: 1 daemon active (1 hosts, 1 zones)

  data:
    volumes: 1/1 healthy
    pools:   11 pools, 177 pgs

    usage:   1.1 TiB used, 4.9 TiB / 6 TiB avail
