Hello, Today I wanted to create a mageia 9 install with a mirror disk. I tried with the mageia installer but I only got errors Choosing Linux RAID on the disk type on both disk I was able to create Raid device md0, once both drives are joined in to raid I cannot install mageia on it. I tried by booting with mageia live and used terminal and start all over again As root I typed fdisk /dev/sda to configure the HDD as Linux Raid I did the same with /dev/sdb I later created raid md0 and added both drives mdadm --create /dev/md0 --level=mirror --raid-devices=2 /dev/sda1 /dev/sdb1 Once mirror started and I made sure it was done using mdadm --detail /dev/md0 I tried to install mageia to device Raid and it did not work. It seems it does´nt support Raid level1=mirror on MCC What if I need to install mageia as server and have my boot drive as raid 1? This is what I want to do.. https://youtu.be/rJzHpc1kQW4 Regards
Assigning to the tools maintainers. I think the answer is going to be that /boot must be on a regular partition, not part of the raid array so that the initrd can be loaded, but I'm not sure. I've only used lvm raid, not mdadm or dmraid.

yes, boot must be outside of the raid as it needs to be able to load kernel/initrd to load raid support
If not wanting to consume space on drives, i think you can have a small USB flash drive as boot.

I did not see the mirror option on it but will look furter on this since this is the first time I´be worked with software raid on linux and I plan to move all windows servers to linux this year.. Thanks for the tip.
I should add, I was using lvm to make it easier to spread an install over multiple small hard drives, not for data safety. I stopped using it after a lightning strike took out 3 out of 5 isa drives, as well as the motherboard on that old i586 system. Luckily, I had recent offline backups of critical data as the new system did not support isa drives. I switched to a newer computer with larger drives and added a ups. That was years ago. Now I just make sure I keep good critical data backups. I avoid data compression or software that uses it's own format for the backups, and just use rsync.
