Thank you for input! (I really need some hehe)
ok, first, I cannot set a raid 5, for some reason the ServerGuide to my server only allows 0, 1 and 10. Bummer.
About the partitioning:
I tried two different setups, none worked.
1: 6 GB swap and 67GB ext4 root partition (with bootflag
2: 6 GB swap and 67GB ext4 both set to physical volume for RAID (as specified in this guide: https://help.ubuntu.com/12.04/server...tallation.html
Setup #1 procudes the "cannot write ext4 partition error"
Setup #2 procudes the "no root set error" the 67GB partition set with Bootflag
n (as none are specified)
I am kinda new to raids (or haven't worked in computers for 7ish years so kinda lost touch) the server seems to run a hardware raid, so I am unsure if the option to "create MD device" is just creating a software raid on a hardware raid (and causing troubles)
All I have tried has been tried both on raid 0 (Striping) and raid 1 (mirroring) and raid 1 + 1 hot spare, all unsuccesfull.
I am unsure what you mean by creating a boot partition on seperate drives, as the installer only sees one drive (either a 73 GB * 3 striped drive as 1 drive, or a 73 GB drive which is mirrored)
I was hoping that, when the installer had GRUB2 installed, the bios would understand that it should boot on what grub tells it to?
I don't know how to make a seperate drive for booting up on and maybe from there have files and stuff (webserver mostly) run off the striped or mirrored disks?
Really thought the HW raid 0 would just act as a normal harddrive so the normal installation just run through and voilá.
The idea with some other distro is not bad, I might try that, but I am quite stubborn, so I really would love to get the ubuntu installer to work so I knew what caused the problem.
