[Gluster-users] Experiencing errors after adding new nodes

Wed Apr 27 16:23:55 UTC 2011

I know this is an old thread, but when I login to Bugzilla I get this message:

You are not authorized to access bug #2369.

Why would that be?

Rebalance and EPERM, looks like you are hitting http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=2369

Hi,

I had a 2 node distributed cluster running on 3.1.1 and I added 2 more nodes.  I then ran a rebalance on the cluster.

Now I am getting permission denied errors and I see the following in the client logs:

I am running the rebalance again to see if it will fix the layout issue.

Any ideas why I'm seeing these errors after adding new nodes?

Regards,

John Lao
