Re: Gluster peer status disconnected

[Shyam Deshmukh <shyamdeshmukh212@xxxxxxxxx>]

Hi,

Thanks for reply.

I would like to share why this happen,

Actually I am doing this in the college lab, on single workstation,where I have installed VM and 5 nodes.One as client and 4 are in the server pool. College LAN has DHCP server. IPs generated at the time of cluster creation changed due to that reason. Once IP got changed, My gluster cluster got down. showing this above message on peer status command.

 I did changed all hosts configuration,and also stopped and deleted previous volumes created on that. and tried many times to check status of my server pool.

I checked ping , confirmed that daemon is running. and also as per iptables flush command.But it was not working.

Finally I created new nodes in virtual box and created new server pool.

Its working now.

Thanks..

Shyam D.

Hi Shyam,

Were the peers in a connected state anytime *before*?

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 ):

1. Check if the nodes are reachable.. 'ping <ipaddress>'
2. Check if the glusterd daemon is in an active state in all the nodes.. 'service glusterd status'
3. Firewall issue - flush IPtables on the node which is disconnected..  'iptables -F'

Do let us know if this helps..

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.

Thanks,
Shweta

Hi,

I am getting following status and my cluster is down due to the same.
Please help.

gluster@gluster1:~$ sudo gluster peer status

gluster@gluster1:~$

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!
