PATA and software-raid ?

[blondie]

Hello NG,

does anybody have some experience with PATA and software RAID-1 ?
I tried with Promise Ultra 133 TX2 with no success. During the boot process the word "GRUB" appears and nothing else happens.
The RAID partitions can be created by diskdruid and the installation process works fine, but Fedora isn't booting from harddrive.
Is this a general problem using software RAID-1 and PATA or is this a problem with this specific controller ?
Another odd thing is, that the controller reports, that the harddrives don't have the same capacity (differs about 500MB) , whereas diskdruid reports the two harddrives to be of the exact identical capacity.

Greetings

I've been using Linux-native software raid-0 and raid-1 on my Promise Ultra133 for quite some time. One problem that I occasionally run into is that grub fails to install correctly on the mbr. My solution has always been to boot the system into rescue mode ('linux rescue' when booting from the install disc). Then chroot to the FC3 installation and run:
grub
root (hd1,0)
setup (hd1)
root (hd0,0)
setup (hd0)
The above (assuming your /boot dir/partition is on partition-1 of both drives) will install grub to the mbr of both drives in the array. Should fix the problem.
