Lab 9.3

Hi Jerry,
As I imagine a SysAdmin would I tried getting to the root cause of the problem/s:

On CentOS7:
:$ ls -ls /sbin/mkfs*
12 -rwxr-xr-x. 1 root root 11504 jon 17 2014 /sbin/mkfs
208 -rwxr-xr-x. 1 root root 209808 jon 9 2014 /sbin/mkfs.btrfs
32 -rwxr-xr-x. 1 root root 32760 jon 17 2014 /sbin/mkfs.cramfs
96 -rwxr-xr-x. 4 root root 96240 jon 9 2014 /sbin/mkfs.ext2
96 -rwxr-xr-x. 4 root root 96240 jon 9 2014 /sbin/mkfs.ext3
96 -rwxr-xr-x. 4 root root 96240 jon 9 2014 /sbin/mkfs.ext4
36 -rwxr-xr-x. 1 root root 32856 jon 17 2014 /sbin/mkfs.minix
340 -rwxr-xr-x. 1 root root 347344 jon 10 2014 /sbin/mkfs.xfs

So can conclude mkfs.vfat is not installed on my CentOS7.
Remedied by sudo yum install dosfstools-3.0.20-9.el7.x86_64...

On Ubuntu 14.04:
:~$ ls -ls /sbin/mkfs*
12 -rwxr-xr-x 1 root root 9668 feb 12 21:54 /sbin/mkfs
20 -rwxr-xr-x 1 root root 17916 feb 12 21:54 /sbin/mkfs.bfs
32 -rwxr-xr-x 1 root root 30300 feb 12 21:54 /sbin/mkfs.cramfs
0 lrwxrwxrwx 1 root root 6 feb 16 22:26 /sbin/mkfs.ext2 -> mke2fs
0 lrwxrwxrwx 1 root root 6 feb 16 22:26 /sbin/mkfs.ext3 -> mke2fs
0 lrwxrwxrwx 1 root root 6 feb 16 22:26 /sbin/mkfs.ext4 -> mke2fs
0 lrwxrwxrwx 1 root root 6 feb 16 22:26 /sbin/mkfs.ext4dev -> mke2fs
28 -rwxr-xr-x 1 root root 26712 mar 18 2014 /sbin/mkfs.fat
28 -rwxr-xr-x 1 root root 26220 feb 12 21:54 /sbin/mkfs.minix
0 lrwxrwxrwx 1 root root 8 apr 18 17:11 /sbin/mkfs.msdos -> mkfs.fat
0 lrwxrwxrwx 1 root root 6 apr 18 17:11 /sbin/mkfs.ntfs -> mkntfs
0 lrwxrwxrwx 1 root root 8 apr 18 17:11 /sbin/mkfs.vfat -> mkfs.fat

So can conclude that there is a softlink from mkfs.vfat to mkfs.fat on my Ubuntu 14.04.

Googling the message indicates that this is a known message:
http://www.linuxquestions.org/questions/linux-newbie-8/unable-to-get-drive-geometry-when-mkfs-vfat-784956/

...and...

http://www.certdepot.net/rhel7-use-vfat-ext4-xfs-file-systems/
seems to suggest that
"mkfs.fat 3.0.26 (2014-03-07)
unable to get drive geometry, using default 255/63"

...is not an error message.
