I assume you mean Red Hat Enterprise Linux 6.3, not Red Hat Linux 6.3 which would be over a decade old if it had existed, which it didn't.

Check out the documentation on RedHat's website

hi, yes Red Hat Enterprise Linux 6.3

Is it 64 bit?
Incidentally, it should be on 6.5 by now...

I am sorry it is 64 bit, dose it make any deference

Thanks and Regards

The trivial answer is "mkfs"... By default it will use the size of the partition you specify...

The longer answer is that you have to assemble the 10 or 20TB partition from multiple disks...

You get to lookup "LVM" handling if you have to do it in software, or reference the RAID documentation for the controller you are using.

Hi jpollard, I can create a partition of the size 20TB using parted, but when I try to use mkfs it give me an error that it can not create the file system, and the largest file system that I can create is 5TB

According to the documentation the largest file system size for ext3/ext4 is 16TB or 100TB for xfs.

By what method did you assemble/create the 20TB partition?

Try xfs maybe or get creative with zfs or btrfs.

According to Redhat, they will help you with this if you are a paying customer.

You ARE a paying customer right?

There are your filesystem limitations.

Use xfs, ext3/4 always give me issues with >12TB
