CentOS: trouble setting up a RAID
I am working on building a file server to store all of my movies so that I can pull them up on my different machines using Boxee. I have (3) 1Tb drives attached to a SATA controller and I want to setup a software RAID 0.
Here is what I have done thus far:
created a /etc/raidtab
*** device /dev/sda is my main boot drive which is a 250Gb SATA drive connected straight to the motherboard***
I then used mdadm to create the array
I created a mdadm.conf file at /etc/mdadm/mdadm.conf and used mdadm -Es to add the new RAID
mdadm --create /dev/md0 --level=0 --raid-devices=3 /dev/sdb /dev/sdc /dev/sdd
next I formated the new device with mke2fs
mdadm -Es | grep md0 >>/etc/mdadm/mdadm.conf
I created a directory off of root for the files and mounted the device
Finally I added it to my fstab
mount /dev/md0 /videos
When I reboot the machine fails to mount the device when I run cat /proc/mdstat the raid device is no longer running.
/dev/md0 /videos ext2 defaults 0 0
I am not sure where I am messing things up, can anyone point me in a direction?
