XFS is quite stable in CentOS 6.4 64bit.
there was a flakey kernel issue circa 6.2.

XFS+LVM+mdraid does this, but it requires several manual steps...
I'd take the new drives, add them to a new md mirror, then add that md
device to the volume group, then lvextend the logical volume, and
finally xfs_grow the file system. yes, thats a bunch more steps than
the zpool/zfs commands, but in fact zfs is doing much the same thing
internally.
I believe lvm also lets you replace pv's in the vg with new larger
ones. I haven't had to do this yet.
