So I have made the mdRaid work finally and I have tested it: The performances look slightly better than using the RAID card during file transfers (+/- 10 Mo/s better) However, I have an issue: when I reboot, mdadmin doesn't re-spawn the array entirely: /dev/md0 --> is the Raid 1 of sdb sdc /dev/md1 --> is the Raid 1 of sdd sde /dev/md3 --> is the RAID 0 of md1 & md0 and this one doesn't come up at reboot.
I have to rebuild it with mdadm --create /dev/md3 --chunk=64 --level=0 --raid-devices=3 /dev/md0 dev/md1 and remount the file system.
You don't have to recreate it, you can just assemble it. Nonetheless, it should certainly come up automagically. What do you have configured in /etc/mdadm.conf ?

I had no /etc/mdadm.conf so I wrote it myself from the example in /usr/share/doc/package/mdadm. No success. I tried the assemble option: no success. It says something weird about the file system on md0 and md1 such as it's formated in ext2. I never done that?!? I have just formatted the md3 in ext3. What happens during boot is that the md0 abd md1 are Ok, but when the mdadm wants to set the md3, it says that the md0/1 are not ready. I guess there is a tweak or smthg? ElPaPaNoeL
