Hi John,
Yes, it was working for some time and then I tried updating the run_dir on the cluster for another reason so I had to restart the cluster. Now I get the issue with the socket creation. I tried reverting the run_dir configuration to default and restarted but the issue persists. I looked for anything listening on that port but didn't find anything: [root@carf-ceph-osd15 ~]# netstat -a | grep -i 7000 tcp 0 0 carf-ceph-osd15.w:37000 carf-ceph-osd17.w2:6894 ESTABLISHED tcp 0 0 carf-ceph-osd15.w2:6960 carf-ceph-osd17.w:37000 ESTABLISHED tcp 0 0 carf-ceph-osd15.w2:6863 carf-ceph-osd16.w:37000 ESTABLISHED tcp 0 0 carf-ceph-osd15.w2:6855 carf-ceph-osd17.w:57000 ESTABLISHED And lsof didn't return anything either. Guess I could try a reboot... but would prefer to figure it out, -Bryan -----Original Message----- From: John Spray [mailto:jsp...@redhat.com] Sent: Friday, September 22, 2017 2:32 AM To: Bryan Banister <bbanis...@jumptrading.com> Cc: ceph-users@lists.ceph.com Subject: Re: [ceph-users] Ceph mgr dashboard, no socket could be created Note: External Email ------------------------------------------------- On Thu, Sep 21, 2017 at 3:29 PM, Bryan Banister <bbanis...@jumptrading.com<mailto:bbanis...@jumptrading.com>> wrote: > I’m not sure what happened but the dashboard module can no longer startup > now: I'm curious about the "no longer" part -- from the log it looks like you only just enabled the dashboard module ("module list changed...")?

I would look for other processes already listening on the same port that dashboard is configured to listen on (7000 is the default), then check for any security configuration changes (e.g. related to selinux) that might be preventing it listening.
