Hi, Actually I am not sure if the upgrade (I am using Ubuntu 12.04) actually will restart the daemon as a result of that I tried rebooting one of them first. However, in a previous situation I had (while all of them were still running the older 0.61.4). Rebooting the same MON, did not restore the quorum also, so I am not sure what may cause this but I supposed it maybe some other reasons. Anyway I had tried your advice and reboot all the MONs again and the quorum seemed to be back up again. Thanks.

So you say you've upgraded all nodes to 0.61.7 and then restarted one, and this happened? Have you restarted the other mons after you upgraded to 0.61.7, or are they still running an older version? It could be you simply need to restart the two other mons to fix the problem. -- Jens Kristian Søgaard, Mermaid Consulting ApS, jens@xxxxxxxxxxxxxxxxxxxx, http://www.mermaidconsulting.com/ ------------------------------------------------------------------ - - DISCLAIMER: This e-mail (including any attachments) is for the addressee(s) only and may contain confidential information.
