I just read the rhel6 filesystem size limit. http://www.redhat.com/rhel/compare/ It says 16TB limit for ext4 (same as ext3)?!?! I thought ext4 was supposed to support 1EB ( ~ 1 million TB) limit. That was one of the main advantages of rhel6. After a little more digging all I found was that the user space formatting tools (mkfs.ext4) only support 32bit filesystems (not 48bits). I'm surprised about this, I thought people would be waiting for >16TB support in rhel6. Does anyone know if this is going to change in point releases of rhel/centos6?
