I am currently trying to set up software RAID while installing Sarge. I
have two hard drives, both with one partition "physical volume for RAID",
as well as a RAID 1 device that uses both. Everything goes fine until I
try to write the partition table on the RAID device. I get the following
errors:
[?] Partition disks
Warning!
The kernel was unable to re-read the partition table on /dev/md/0 (Invalid
argument). This means Linux won't know anything nothing about the
modifications you made until you reboot. You should reboot your computer
before doing anything with /dev/md/0.
