mobo raid on fedora?

jedimastermopar · 07-25-2007, 11:14 AM

Ok, so I have installed raid 1 on fedora 7
This is using the mobo raid(fastrak or something similar)
I pulled one drive to test it to see how it is working if at all.
The machine boots and gives me a bios warning that the raid is degraded, all normal.
That machine starts to boot up and gets past Grub, and and tries to mount the LVM,
It ends up with a kernel panic - not syncing: Attempting to kill init!

I would have thought it would just boot into redhat.
Is this normal behavior?

No it's not normal. Was the array synced before your test?

This is using dmraid, right? Did you pull drive 1 or drive 2? If drive 1, try putting the active drive over in drive 1 position to see if that helps.

I don't know if it is using dmraid. How do I find out? The drives were synched accoring to the Bios Raid utility.
I pulled drive 1. I will pull drive 1 again, and put drive 2 in drive 1's slot.
I should mentione I guess that this is an IBM Xseries 306m

Normally, a motherboard RAID, where the BIOS creates and syncs the RAID, is what's called a FakeRaid and is actually a Software not Hardware RAID. But, on an IBM Xseries 306m? I have no idea. Is your data accessed through /dev/mapper/pdc_somethingorother? If so, then you're running dmraid during boot to gain access.

It is definatly a software driver based raid. FC7 is the only thing it seems to actually work on under linux. Yes, the drives are all partitioned through a /dev/mapper

I would check with the dmraid site to see how far along they are with Linux tools for dmraid arrays. They also have a very helpful mailing list.
