I'll let Eric or Lukas comment, but as far as I know the ext4 in the
RHEL 6 kernels has been quite stable (there are a lot of bug fixes
that have been backported to the RHEL 6 kernel, and while it doesn't
have some of the newer ext4 features, it doesn't have any of the more
exciting bugs that might come with the newer features :-).

So I really would strongly suspect the SAN or the SAN-attached storage
as being flaky, causing the file system corruptions which is leading
to the kernel and e2fsck complaining.

Right, ext4 is default in RHEL6 and well tended.  We'll let support look
at the case, and see what's going on.  But I'd certainly troubleshoot
the san as well, esp. to be sure HA is set up properly and not mounting
it twice on 2 nodes etc.
