Re: [CentOS] mkfs.ext3 on a 9TB volume

As I mentioned, I'm running centos-4, which, as we all know, is based off RHEL 4. If you go to http://www.redhat.com/software/rhel/features/, they explicitly state that they support ext3 FSs up to 8TB.

Wow! Odd! RH says 8TB but ext3 FAQ says 4TB.

From my personal testing on CentOS 4.1, you can't go over 4TB without kludging.

I then did a software RAIDO across them, and finally:

mke2fs -b 4096 -j -m 0 -R stride=1024 -T largefile4 /dev/md0

Joshua, thanks for the reply on this. There's something kludgy about having to do softraid across 2 partitions before formatting. It adds a layer of complexity and reduces reliability. Is that the trick RH recommended to go up to 8TB?
