NSA325: Raid1 setup possible ?

[waewaeebnaiu]

Hello,

I own a NSA325v2 which I would like to use with 2x4TB disks in a raid1 setup for the data partition. In addition to that I'd use a USB 3.0 4TB drive to do backups of the data on the raid1 with rsync.

I saw http://archlinuxarm.org/platforms/armv5/zyxel-nsa325. That installation guide talks about the left disk being formated. Will I then be able to extend that single drive backup installation to a raid1 setup?

Wake on lan is working for the used ethernet hw in the NSA325 ?

Thanks
W.

You could do a dmraid.

After my install, I reformatted the first drive to have 3 partitions, the 16M boot partition, the rootfs in a 25G partition and then the remainder is the data partition.

Hello WarheadsSE & Socialtom,

thanks for your answers.

@WarheadsSE:
A dmraid is a fakeraid? What advantages does that have over the the "normal" linux raid with an mdadm raid1 ?

@Socialtom:
Did you reformat your first drive during the installation on the NSA325 itself. Or after the installation in the NSA325 itself. Or in another computer after the installation, or before the installation ? With which program did you reformat ? I have used gparted as a graphical frontend from live cds before and used fdisk & friends from the cli before that.

Thanks

dmraid/mdadm should both work.

You could also use btrfs on the data partition, that can also do software raid.

Its what I'm doing on my NSA325 - all be it with only one disk, so I'm not doing raid.

Oh yes, using btrfs on the root partition is a bit of a hassle, you'll need to set up an initramdisk as the default alarm kernel doesn't have the btrfs statically included. So its easier to keep the root fs as a standard ext parition.
