Re: RAID - mdadm Help. (Newbie in Linux)

["Mark Cuss" <mcuss@cdlsystems.com>]

You need to make the filesystem on your new /dev/md0 device...  You have 
many choices as to which filesystem to use, but ext3 is the most common in 
Linux.

Doing a mkfs.ext3 /dev/md0 should do the trick.  All of the parameters are 
listed in the man page for mkfs / mkfs.ext3.

This is the same as formatting a disk under Windows - all data is torched 
from that device, so make sure there isn't already a filesystem or valuable 
data on it.  If you've just made the RAID device, then there won't be.

To automount it, add a line to fstab...  You've got it essentially right 
with the line you have below....  If you choose to use ext3 as the 
filesystem, just change vfat to ext3.
