Try to connect to dashboard

You have the list here:
list_of_dashboards

Connect to any of the monitors

Clover:

  • avmlp-osm-00 Larry: * avmlm-osm-00

Epayments-oss:

  • ACCLM-OSM-00*


Any of them will do the job.

Check the status of the cluser

As root:

ceph health detail

And:

ceph -s


Normally it should be OK:

avmlp-osm-001 /home/ceph # ceph -s

If the status is NOT OK, escalate!!!!

Restart the dashboard

First, see the status:

ceph mgr services

Then restart it:

ceph mgr module disable dashboard
ceph mgr module enable dashboard

And check again:

ceph mgr services


It take some seconds to restart. You'll see:

avmlp-osm-001 /home/ceph # ceph mgr services
{
    "dashboard": "https://avmlp-osm-002.ciberterminal.net:8443/"
}
avmlp-osm-001 /home/ceph # ceph mgr module disable dashboard
avmlp-osm-001 /home/ceph # ceph mgr module enable dashboard
avmlp-osm-001 /home/ceph # ceph mgr services
