Installing OpenSuse on a software-based RAID array is not possible if OpenSuse is providing the software. Technically, the only solution left for this case is to use a hardware RAID controller and install OpenSuse on the hardware-based RAID array.

This OpenSuse-on-RAID solution would be very secure in the sense that the server would be very protected against downtimes. However, the solution I was seeking was not targetting downtimes, but only the data safety. I can accept downtimes, but I want to be sure that several years of digital photography is not lost in a disc failure.

The second question you ask (re-installing OpenSuse on hda and still access the RAID array) is also an interesting one since it would be the normal situation after a boot disk crash.

I did not do it, but it would be a matter of following the steps:

  1. Install OpenSuse on /dev/hda
  2. Enter YAST2 configuration and notice the presence of /dev/hdb1 and /dev/hdd1 as unused OxFD Linux RAID partitions
  3. Add/Create a RAID array using the two unused/available partitions
  4. Apply and start using the array

If the initial crash left the RAID array in a safe configuration, it will be enough. If the crash was really severe, you’re left with the RAID reparation described in the other article of this series “Testing RAID-1 on OpenSuse“.

Did you try to install a RAID array on a hda and hdb drive set?
In other words, that means installing an opensuse on a RAID array from which the system will boot…
Cheers,

Nice work on RAID installation & testing in Opensuse!

I do have a few questions….

What if your hda drive fails???? Your NAS will not be accessible to others on the network because the system supporting the NAS would be down?!?!

Did you try to reinstall opensuse on a new hda drive and still access your RAID array based on hdb and hdd?? (I guess hdc is your DVD player)

Cheers,

JC
