I'm trying to create some redundancy in booting linux using raid 1 as well as some other raid arrays. It's my first install using linux (no other OS is on this box) and I have gotten it loaded but I'm not sure where I am. Here is some file info:

/proc/mdstat

md1 : active raid0 hdg3[4] hdf3[3] hde3[2] hdb3[1] hda3[0]
526890880 blocks 128k chunks

I want to use md0 for the the linux root file system and use it to boot. I don't belive I accomplished this though. Also, does the md1 and 2 look OK? How can I check to see if the raid array's are in fact working.

Any help will be very much appreciated.

Thanks

All 3 of your arrays up and working, note the [5/5] [UUUUU], each U means that the disk is up.

I think you need to point grup at the md0... array but not sure - can you provide your /etc/fstab file please

Thanks for the reply, here's the file.

/etc/fstab
/dev/hda1 / reiserfs acl,user_xattr 1 1
/dev/md0 /boot reiserfs acl,user_xattr 1 2

Appreciate the help

Your setup looks ok, though it would be better if possible to put / on the mirrored raid device too.

However you will need to get grub to write out to the other mbr on the second drive, theres a howto on this here

http://lists.us.dell.com/pipermail/l...ly/014331.html

theres a raid monitor daemon you can run called "mdadm" which can alert you to drive and raid problems via email etc

Thanks, jmeads. I'll give it a try.
