[Gluster-users] Issue in Adding/Removing the gluster node

Fri Feb 19 12:41:31 UTC 2016

Hi Abhishek,

Peer status output looks interesting where it have stale entry, technically it should not happen. Here few thing need to ask

Did you perform any manual operation with GlusterFS configuration file which resides in /var/lib/glusterd/* folder.

Can you provide output of "ls /var/lib/glusterd/peers"  from both of your nodes.

Could you provide output of #gluster peer status command when 2nd node is down  

Can you provide output of #gluster volume info command

Can you provide full logs details of cmd_history.log and etc-glusterfs-glusterd.vol.log from both the nodes.

You can restart your glusterd as of now as a workaround but we need to analysis this issue further.

Thanks,
Gaurav
