Mounting 13TB Raid

This is some quick info I learned while trying to mount a 13TB partition in RHEL 5.3. The main thing is that fdisk does not like to make partitions larger than 2.2TB because dos labels are not recognized. The second is that ext3 file system doesn't like anything bigger than 8Tb. So here is what I did to go around it. I had to used parted instead of fdisk to overcome that 2TB limit.

#parted /dev/sdd
#mklabel gpt
>mkpart primary 0 13000G
>quit
#yum install e4fsprogs
#mkfs.ext4 /dev/sdd1

To lay this all out I had to rename the label of the partition to gpt so I could use the larger partitionsize and then I installed support for ext4 and used that as the filesystem. Yes I know I punked out a bit but I am sick of trying to find work arounds for ext3.

APPENDED NOTE!!

You can't mount ext4 in RHEL just yet lol kind of important. I went back and did

#mkfs.ext3 -F /dev/sdd1 

and it took the filesystem
