This is on a fresh computer (super computer actually). It got to me with 15T on the home mount and 50G on the root. I tried allocating 7T to root and resizing (since I'm putting a local yum repo on this machine as it has no internet access nor will it ever).

I tried following the instructions here: Centos 6.3 disk space allocation but something went wrong and the home won't mount again. Instead I get from dmesg | tail:

EXT4-fs (dm-2): bad geometry: block count 4294967295 exceeds size of device (1342177280 blocks)

df -h nets this output:

Filesystem                                  Size    Used   Avail Use%    Mounted on
/dev/mapper/VolGroup-lv_root   7.0T  3.6G  6.6T   1%          /
tmpfs                                         190G  216K  190G   1%        /dev/shm
/dev/sda1                                485M   38M   422M  9%    /boot

I didn't have any files on /dev/mapper/VolGroup-lv_home. Will simply running mke2fs fix it to be mountable? What sort of options should I run it with. I've never resized volumes before or used mke2fs. I don't want to make this mess worse.
