Gluster users - Nov 2010 - Creation of volume has been unsuccessful

Hi,
When running the following command on host named gluster1:
#gluster volume create test-volume gluster3:/data1

I get:
Creation of volume test-volume has been unsuccessful

I tried to look for clues in the logs but didn't find one.

I have 4 nodes: gluster1,gluster2,gluster3,gluster4


/etc/glusterfs/glusterd.vol 

volume management
    type mgmt/glusterd
    option working-directory /etc/glusterd
    option transport-type tcp       
    option transport.socket.keepalive-time 10
    option transport.socket.keepalive-interval 2
end-volume

gluster peer status(from gluster1)
Number of Peers: 3

Hostname: gluster4
Uuid: 7ca19338-5f45-448a-a324-648e990a35de
State: Peer in Cluster (Connected)

Hostname: gluster3
Uuid: 1679a2a2-d3fd-4b9b-aa61-93a94287b565
State: Peer in Cluster (Connected)

Hostname: gluster2
Uuid: 707c894e-6c0d-471e-afc5-09ea0dbf2bbc
State: Peer in Cluster (Connected)

What am I missing?

Thanks for your help,
Dan

hi itzik,
       Could you attach the zipped glusterd logs present in /etc/glusterd/logs
on all the machines. That will help us figure out what the problem is.

Thanks
Pranith

hi itzik, 
This looks similar to
http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=1855
The reason for the bug is that in the 3.1 implementation, the host aliases are
not handled properly for localhost. Are you using 3.1 release?. If yes the bug
is fixed from
http://ftp.gluster.com/pub/gluster/glusterfs/qa-releases/glusterfs-3.1.1qa1.tar.gz


Thanks

hi itzik, 
According to the logs, The DNS resolution of gluster3 on the same machine
failed.
======gluster3.log===== 
[2010-11-10 18:14:07.26112] E
[glusterd-op-sm.c:413:glusterd_op_stage_create_volume] glusterd: cannot resolve
brick: gluster3:/data1
[2010-11-10 18:14:07.26136] E [glusterd-op-sm.c:4664:glusterd_op_ac_stage_op] :
Validate failed: 1


This can happen if the DNS is not setup properly or /etc/hosts files are not
setup properly. Could you provide /etc/hosts contents on all these machines to
check if they are set up properly?


One question: Will it be ok if I CC this thread to gluster-users?. I think it
would be helpful for the community to know about issues like these.


Thanks 
Pranith.
