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
Number of entries: 4

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
