Subject: formatting a 12.73 Tb disk on ROCKS 5.2

I have a raid-5, /dev/sda on a NAS node that has 12.73 Tb of space.

mkfs xfs /dev/sda1
mke2fs 1.39 (29-May-2006)
mkfs.ext2: invalid blocks count - /dev/sda1

I can use

mkfs.ext3 /dev/sda1 works, but it only formats the first 2Tb of space.

filesystem            Size  Used Avail Use% Mounted on
/dev/sdb1              19G  2.8G   16G  16% /
/dev/sdb5             875G  200M  830G   1% /state/partition
/dev/sdb2             4.8G  184M  4.4G   5% /var
tmpfs                 3.9G     0  3.9G   0% /dev/shm
/dev/sda1             2.0T  199M  1.9T   1% /bigdisk1

How do I get the complete raid system formatted?

Sounds like /dev/sda1 is defined as a 2T partition?  Run fdisk (or other partitioning tool) to see what partitions are defined on /dev/sda/
