 |
|
I am trying to install gentoo on a RAID array, i have a Promise ATA66 raid controller and i have 2 1.6gig hds in mirror.My RAID hd is at /dev/hde so i created 2 partitions on it 1 for /boot and one for / after i emerged grub
| Code: |
grub
root (hd3,1)
setup (hd3)
Error 17: Cannot mount selected partition
setup (hd0)
Error 17: Cannot mount selected partition
setup (hd1)
|
Anyway i tryed to run the setup command on any other partition with same error. I do not know how i can get a friggin bootloader working with my RAID array.
Does anyone know ?? |

ahh... if you are accessing hde, then it means you mustn't have loaded the raid driver.
you need a 2.4 kernel.. ??

Hello!
Shouldn't it be
as your disk is hde?
Anyway, are you sure, the RAID driver is compiled and ( - if used as a module - ) inserted cleanly?
Greetings,

| I dont think there is anything wrong with the module, it is the gentoo live cd that detects it and inserts it, and already i have emerged system and did bootstrap and setup kernel installed other software too on the RAID on the /dev/hde2. /dev/hde1 is just for boot purposes thats where my bzImage goes and the grub conf etc. |

/dev/hde is only half of the array, /dev/hdg is the other half, and /dev/ataraid/disc0/disc is the whole array.
If you wrote any data to an individual drive, it would have corrupted the array, and made it unbootable.
BTW, once you have GRUB setup properly, the array will show up as the boot drive (hd0). |

oh crap really ?? so i shouldnt of formatted /dev/hde but /dev/ataraid/disc0/disc ???
what i did is i thought that /dev/hde is the whole array, that would explain some things i guess.
So then i should do cfdisk /dev/ataraid/disc0/disc then mkreiserfs etc and when i get to grub ill just use hd0 ?? how would i tell grub that hd0 is /dev/ataraid/disc0/disc ??
Thank you for the info |

that's what I was saying up above 
grub will know it is the first drive, and therefore hd0.
you may need to make a grub boot disk and reboot, then isntall grub to mbr from the disk..
