Create a RAID1 Mirror on NSA325?

[SomeoneOnLine]

If I have ALARM installed on the left drive/sda, how would I go about creating a raid1 mirror between the 2 drives (left and right drive) if the OS is already installed on 1 of them?

Thanks,

This belongs under V5/Kirkwood now.

I believe the answer for this mdadm raid.

Could I follow the below tut on howto setup it up?
https://wiki.archlinux.org/index.php/Co ... RAID_array

It says at the top that it is outdated. Will that cause me problems following the tut?

If not could you recommend one for me to follow?

That's not quite going to cover it.

I dug around, and here is what I have found:
- You need to create a uInitrd (and add that to uboot's bootcmd's)
- You need to alter the kernel command line from uboot
- You need to be willing to re-make the original disk if you screw it up

You can also shrink the OS partition, and create a raid1 array on a second partition, in combination with an (equal sized) partition on the 2nd disk.

BTW, in my opinion raid1 is overrated. You're better off using a script which backups your data once a day, or something like that.

Mijzelf is correct.

If you opt to not raid the rootfs, but the media partition, this is FAR less complex.

After thinking about it. I agree. Less complicated is better (kiss) in my case. Maybe I can just create a media partition on each drive and use rsync to mirror sda and sdb or something. I just want some kind of redundancy between the core data I put on the drives in case of a drive failure.

would it be possible to put alarm in NAND like the stock ZyXel firmware? Then it might be easier. I know that the NAND on the 325 is only 128MB so my guess it no.
