====== Troubleshoot ======
===== Try to connect to dashboard =====
You have the list here:\\
[[linux:ceph: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:
<code bash>
ceph health detail
</code>
And:
<code bash>
ceph -s
</code>
\\
Normally it should be **OK**:
<code bash>
avmlp-osm-001 /home/ceph # ceph -s

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

===== Restart the dashboard =====
First, see the status:
<code bash>
ceph mgr services
</code>
Then restart it:
<code bash>
ceph mgr module disable dashboard
ceph mgr module enable dashboard
</code>
And check again:
<code bash>
ceph mgr services
</code>

\\
It take some seconds to restart. You'll see:
<code bash>
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                                                                                                                                                                     
{}
avmlp-osm-001 /home/ceph # ceph mgr services
{
    "dashboard": "https://avmlp-osm-002.ciberterminal.net:8443/"
}
