trouble booting raid1
Hi All,
I'm trying to make Debian boot from a set of 4 disks using RAID1 for /
boot and RAID5 for /root. All goes wel until after reboot, then the
bootable media is no longer seen by the machine.
I'm using:
- Asus P4P800 mobo
- Promise Fasttrack S150 SX4 fakeraid controller
- 4 80GB SATA disks
- Debian Sarge with 2.6 kernel
the fakeraid card is *not* configured with a raidset as I's expect
that to conflict with Linux softwareraid. It's simply used as a 4
port SATA controller.
Based on several howto's I do the following:
1. start installer with expert26
2. when I reach the partitioner I choose manual partitioning:
a. format each disk
b. partion _each_ disk for use by raid:
1 partition 509,9 MB bootable
1 partition 79,5 GB
c. RAID setup:
RAID1 with 4 509,9 MB partitions
RAID5 with 4 79,5 GB partitions
d. partition RAID
RAID1 set as ext3 /boot
RAID5 set as lvm
e. LVM setup:
Volume group vg00
logical volume root 236.4 GB
logical volume swap 2.1 GB
f. partition lvm volumes:
lv root as ext3 /root
lv swap as swap
After this my RAID/LVM setup looks like this:
LVM VG vg00, LV root - 236.4 GB
#1 236.4 GB ext3 /
LVM VG vg00, LV swap - 2.1 GB
#1 2.1 GB swap swap
RAID1 device #0 - 509.8 MB Software RAID device
#1 509,8 MB ext3 /boot
RAID5 device #1 - 238.5 GB Software RAID device
#1 238,8 GB lvm
SCSI1 (0,0,0) (sda) - 80.0 GB ATA WDC WD800JD-60JR
#1 primary 509.9 MB Bootable raid
#2 primary 79.5 GB raid
SCSI2 (0,0,0) (sdb) - 80.0 GB ATA WDC WD800JD-60JR
#1 primary 509.9 MB Bootable raid
#2 primary 79.5 GB raid
SCSI3 (0,0,0) (sdc) - 80.0 GB ATA WDC WD800JD-60JR
#1 primary 509.9 MB Bootable raid
#2 primary 79.5 GB raid
SCSI4 (0,0,0) (sdd) - 80.0 GB ATA WDC WD800JD-60JR
#1 primary 509.9 MB Bootable raid
#2 primary 79.5 GB raid
3. Continue installer:
a. base install etc
b. install grub on boot master record
Then after reboot, the machine doesn't see the bootable media and
asks for reboot or inserting of bootable media
It seems the Promise Fastrack doesn't work without a raid setup of
it's own, it doesn't present itself to the system as having usable
media. So I then tried configuring the fakeraid card with a RAID5
set. after reboot GRUB loads:
GRUB Loading stage 1.5.
GRUB loading, please wait...
and then it seems to hang with no disk activity...
Setting up the Promise fasttrack with RAID10, it just hangs with a
blinking cursor.
Trying LILO in stead of GRUB didn't succeed either.
What am I missing here? I've read through a lot of info (including
several recent posts on this list on RAID issues) but could not find
anything that could shed some light on this problem. Any help welcome.
TIA
