Kernel errors on a 12 Tb disk partition

[Margaret Doll]

How do we determine the cause of the errors on a 12 Tb partition and
how do we get ride of them?


> We created a 12 Tb partition on a new RedHat system using

Use parted on the device.
In the example below /dev/sdc is a 12 Tb auxilary disk.
parted /dev/sdc	
mklabel GPT	change label to GPT
mkpart primary 0 12999Gb	create partitions
mkfs 1 ext2	create an ext2 filesystem
on the partition
ext3 is not supported in parted in systems.

Create a mount directory for the new filesystem.
mkdir /mountdir
where mountdir is changed to match your environment.
Edit /etc/fstab, adding a line for the new filesystem.
/dev/sdc1 /mountdir ext2 defaults 1 2
where sdc1 and mountdir are changed to match your environment.

We are not getting errors on the partition.  The 12 Tb partition is   
the only ext2 partition on the system.
