Hi, I have red the HOW TO create software raid on Ubuntu in this net, but I cant create the raid by folowing this how to. I have spare mashine P4 with Abit AL8 motherboard and 2 SATA WD1200 HDD, it looks cool for my needs. I want to crate raid 1 on it with Ubuntu 8.04 server. But when I creating partitions on sda and sdb (40GB, 1.2GB, 78.8GB) and want to configure raid (creating md devices), I geting error - there is no linux raid partitions, or they in use (or something). When I try to delet md devices, that already apears for some reason, /dev/md0 device, it contains sdb and sda inactive partitions (I do not created that device) geting error: "there was an error deleting the multidisk device. It may be in use.". After I deleting some parttition and creating it again I can specify the md devices (sda1 sdb1, sda2 sdb2, sda3 sdb3), after I pres finish the md devices do not apears. Where is the problem, does Ubuntu do not suport that motherboard or hdd. Thanks for your answers.
