Error View # ceph -s cluster: id: ce2af227-473a-4d73-a817-512a17f235ac health: HEALTH_ERR Module 'dashboard' has failed: IOError("Port 7000 not free on '172.16.13.151'",) services: mon: 3 daemons, quorum dlw-1,dlw-2,dlw-3 (age 3m) mgr: dlw-2(active, starting, since 0.918549s), standbys: dlw-3, dlw-1 osd: 8 osds: 8 up (since 5w), 8 in (since 5w) data: pools: 0 pools, 0 pgs objects: 0 objects, 0 B usage: 8.1 GiB used, 784 GiB / 792 GiB avail pgs: error handling

Error Literally means that port 7000 on node 151 is occupied, causing the dashboard module to fail View configuration

# ceph config dump WHO MASK LEVEL OPTION VALUE RO mgr advanced mgr/dashboard/server_addr 172.16.13.151 * mgr advanced mgr/dashboard/server_port 7000 * mgr advanced mgr/dashboard/ssl false *

Port 7000 on the 151 machine remains the same because mgr uses 7000.

# netstat -nap |grep 7000tcp 0 0 172.16.13.151:7000 0.0.0.0:* LISTEN 1948234/ceph-mgr # ceph mgr services{ "dashboard": "http://172.16.13.151:7000/", "prometheus": "http://dlw-2:9283/"}

Note that the currently active mgr is dlw-2

Try changing dashboard to dlw-2 node

# ceph config set mgr mgr/dashboard/server_addr dlw-2# ceph mgr module disable dashboard # ceph mgr module enable dashboard --force

Check the current status. Cluster is back to normal.
