Re: Intel Storage Manager Raid 5 support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Many tx .. However ... after spending a day fiddling and googling .. it appears that I need the version for
2.6.24-19 ... not 16 as per your post.

check out this link ..

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/220493

Being a newb I have no ideas :-(

Attached is some snips of my attempts to-date...  Still does not like it .

Makes all of the right noises but there is nothing in /dev/mapper

And when I do a modprobe -r
and then a modprobe  dm-raid45
 it comes up with  invalid module format.

Please help

Regards
Peter

I believe this is in hardy-updates:

When I do an dmraid -l, it says that only raid 0 and 1 are supported for

  Follow the instructions in THIS bug:

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/220493

  I used that to boot up Ubuntu LiveCD and installed Gentoo :) Anyway, the key part is this (for amd64, for x86, it's there too).

sudo su
echo "deb http://archive.ubuntu.com/ubuntu hardy universe" >> /etc/apt/sources.list
apt-get update; apt-get install dmraid
cd /lib/modules/2.6.24-16-generic/ubuntu/md
wget http://launchpadlibrarian.net/14522732/dm-raid45.ko-amd64
mv dm-raid45.ko-amd64 dm-raid45.ko

Edit /lib/modules/2.6.24-16-generic/modules.dep and add
/lib/modules/2.6.24-16-generic/ubuntu/md/dm-raid45.ko: /lib/modules/2.6.24-16-generic/kernel/drivers/md/dm-mod.ko

dmraid -ay

Then you can mount your raid5 volumes just fine.

Again, this is partially due to the fact that the patches here expect dm-raid4-5.ko, not dm-raid45.ko (even though Thomas Backlund on this list said that he's never had this issue - so not sure why this isn't being addressed).
