Thank you for your reply.

I've repeated a similar test on my two node cluster like this:

1. shut down node 02
2. on the client run "rm -Rf linux-3.12/"
3. while the rm is running, boot up node 02

That has the following interesting results:

On the client:

rm: cannot remove `linux-3.12/arch/mips/netlogic/dts': Directory not

On the servers:

"gluster v heal ovvmvol0 info split brain" and "gluster v heal ovvmvol0
info heal-failed" both show 0 entries.

It also claims to have healed some files:
# gluster v heal ovvmvol0 info healed
Gathering Heal info on volume ovvmvol0 has been successful

On the client, these three files in linux-3.12/arch/mips/netlogic/dts/
are indeed shown as present.

Still curious if this was a somehow a quorum issue, I added two more
servers, for a total of four servers with one brick each.  Still
replicate 2.  I set cluster.server-quorum-type=server and

I repeated the experiment of shutting down node 02, starting an rm -Rf
on a client, and booting up node 02 again.  This time, it healed
seemingly half the linux-3.12/arch/x86/include/asm/ directory.  As one
might expect, the directory is completely empty on bricks 03 and 04,
while bricks 01 and 02 share the same files.

Should I file a bug about this somewhere?  It seems easy enough to
