Gluster users - Aug 2012 - Problems with volume after brick addition and rebalance

Hello,

I have a v3.3 4 brick replica 2 volume and decided to expand it so I 
added another 4 bricks to it. All went fine and I have not seen any 
issues.
After that I decided it'd be best to issue a rebalance (I would guess 
this is standard procedure after brick addition, no?) and so I did, the 
command reported that it has started successfully.
The problem is that right after issuing the rebalance I can no longer 
perform certain operations on this volume, specifically `ls` on 
directories (ls /blah/file works, strangely enough) and `rm`.
Here's a paste of the rebalance log: http://fpaste.org/vBBb/

2 hours on and the status of the rebalance operation is still in 
progress with 0 files:
http://fpaste.org/zHC7/

The volume contains a mixture of big (50GB) and small files (some 
HTMLs).

All nodes are Centos 6.3 64bit, selinux and iptables turned off. 
Glusterfs was installed from the RPMs provided at gluster.org (having 
tried and hit the exact same problem previously with Kkeith's EPEL 
rpms).

Any ideas?
