Hi Shyam, <br>
<br>
Were the peers in a connected state anytime *before*?<br>
<br>
If yes, then these are the things you can do to troubleshoot and
get the cluster back to normal (some of which Neils has already
mentioned ):<br>
<br>
1. Check if the nodes are reachable.. 'ping <ipaddress>'<br>
2. Check if the glusterd daemon is in an active state in all the
nodes.. 'service glusterd status'<br>
3. Firewall issue - flush IPtables on the node which is
disconnected.. 'iptables -F'<br>
<br>
Do let us know if this helps.. <br>
<br>
Regarding *how* you landed up in this situation, as Atin
mentioned, it would be better to be a little specific on the
things that you did at your end.<br>
<br>
Thanks,<br>
Shweta<br>

<pre>You can probably start by verifying that the hostnames exactly as listed
above can get resolved to their correct IP-addresses. If that works
fine, check if you can connect to port 24007 on those systems.
This might be a network issue, firewall or glusterd is not running
(anymore) on those systems.
Sometimes it also helps to check on other systems, and se if the output
of "gluster peer status" is different there.
Good luck!
