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

Subject: [Gluster-users] Experiencing errors after adding new nodes

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:

[2011-02-24 09:59:10.210166] I [dht-common.c:369:dht_revalidate_cbk] loader-dht: subvolume loader-client-3 returned -1 (Invalid argument)

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
