Lose power recently? Ext2 doesn't like that.

Subject: Kernel errors on a 12 Tb disk partition
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.
