OK, I understand. You could perhaps look at what the kernel in ubuntu 12.04
LTS is like.  (Note: kernels 3.2.0-30 to -33 have a serious problem with
hotswap locking up the kernel; the patch to fix this should be in the -34

Sorry I don't; I wasn't even aware that 5 to 6 upgrade was not possible.
However the release schedules of RedHat are such that you're likely to sit
on either 6 or 7 forever.

With a replicated system you could at least shut down one node, reinstall it
from scratch, reinstall the same version of glusterfs, and re-introduce it
to the cluster.
