RAID problems with 2.6.19 and 2.6.20 kernels [SOLVED]

Hi all,

I've had a server running a software RAID system happily for about a year and a half. Unfortunately, when I recently tried upgrading to the 2.6.20 and then 2.6.19 versions of the kernel, I get a kernel panic saying that the kernel cannot be mounted. I have looked around and found nothing that clearly indicated how to clear this up and trying to reassemble the RAID just resulted in me being told that it was operating and, as such, it won't go.

Anyway, is there some solution to this problem, and, if I do have to reassemble the array, how do I go about doing it? Sorry if I seem dense and all, but I am tired and a bit frustrated that the kernel upgrade didn't go as seamlessly as umpteen past ones have.

Best,

Alex

make sure it's detecting your raid... is md compiled in and working and detected your disks? is the root partition set to the right partition?
what's in your bootup logs?

Hi, thanks for the reply.

Hi,

In the hopes that I won't have to replace the drive, I just used mdadm --add to reconstruct the RAID drive. From what I gathered by watching mdstat, it went well. Looking at /proc/mdstat I now get:

I'm fairly sure they are SATA (they're definitely scsi and SATA was enabled in my last kernel). Where can I find the new information, and, if you would be so kind, what do I need to enable? I set up this machine once way back when and most all the information has left my brain since then!

evoweiss,

The SATA settings that were under SCSI Low Level drivers have been moved to a new section called ATA.

The option names have been preserved (and many new ones added). Look at your SATA settings in your old kernel and choose the same options in their new menu.

As you don't give error messages or tell use what hardware you have, we can't point to specific settings

Hi there,

Ok, thanks for pointing out where the new section is; sorry for not posting more information as I am not at the office and don't have the access I need. I am trying to avoid going into the office this weekend, but wanted to move as quickly forward as possible so that I don't spend all day Monday trying to figure something out.

Anyway, I checked my previous settings with make menuconfig and I had "serial ATA (SATA) support" and "intel piix/ich sata support" build into the kernel. I set ATA device support and intel piix/ich sata support to be built into the kernel. Does this sound right?

Best,

Alex

evoweiss,

Yes. The module names and config options have not changed.
Stick with the old IDE section meanwhile. the IDE drivers are being moved into libsata but they are not yet complete, so don't use the PATA drives under the new ATA menu

Hi all,

Thanks... that did the trick. Everything is humming along nicely now.
