Ubuntu Installation Issues: RAID
I set up the partitions on my hard drives the way I wanted. I have dual 500GB sata drives that I wanted to put in a RAID 0 with 2 partitions. 495GB each for the OS and then the remaining space for swap. When I was done configuring everything and wrote the changes to disk, I got the following error:
“The kernel was unable to re-read the partition table on /dev/md0 (Invalid argument). This means Linux won’t know anything about the modifications you made until you reboot. You should reboot your computer before doing anything with /dev/md0.”
This was followed by an identical error for /dev/md1. I’m still not sure of exactly what caused the error, but the quick fix I used was to hit the ESC key after the errors take place, wait for the menu to show up (the computer wants to install the base system first), then without changing anything else, set up the RAID partition that you are installing the OS, and don’t modify the swap partition or anything else like that. When I did this I still got the error for /dev/md1, but I did not get one for /dev/md0, which is what I am installing the OS to.
