Hello,

Second week now than I'm trying to setup Linux Mint on software RAID5 without success.

I'm able to setup the software RAID5 on the live CD with three 240GB SSD, then the installation setup fails to install the GRUB on /dev/sda

Knowing that /dev/md0 is software thing, I do need to install GRUB on members disks, /dev/sda, b and c but, I have this error:

My motherboard is an Asus PRIME A520M-K and it is supporting hardware RAID up to RAID1, I don't mind to use hardware RAID1 instead of software RAID5, knowing if someday the motherboard is dying I will need to restore the system from a Timeshift snapshot as the new hardware will break the RAID1.

Another issue is, Linux Mint live CD isn't recognizing the hardware RAID array. Is I need to provide a driver? If yes, where to get it and how to easily install it?

I red several tutorials and I'm not able to find my solution.

Thank-you in advance for help.

What is the reason for setting up Linux Mint using RAID?

And more generally, what are the expectations with regards to using RAID at all?

Is there some particular requirement involved?

[ Note: Will leave this thread in Storage for the time being. However, it may be more applicable to the Open Source Category.]

@Ralston18

The reason is: it is a network based workstation that I rely on. I don't want to start over each time a disk is failing, even SSD can fail.

I know than I can do snapshots, this is what I'm already doing. I just want more safety with RAID.

With regards,

Guillaume

Just a question like that, is I need to wait for the syncing get done before installing LM as well as the GRUB? May I install it on /dev/md0 in case of RAID1? But in case of software RAID5, where should I install the GRUB?

Is what I'm asking is something that is regularly performed ? Meant, installing Linux Mint (or other flavors) on a software RAID?

Or, is a installation on a good SSD and a daily snapshot with Timeshift could be more than enough for ensure protection?
