[arch-dev-public] [signoff] mdadm-2.6.8-2
Hi http://bugs.archlinux.org/task/10651 http://bugs.archlinux.org/task/9122 both states raid is broken for more complex setups. According to my earlier mail about assembling raid arrays i wrote a new hook and install file. It uses mdassemble.static from mdadm tarball which is smaller than mdadm.static and does the assembling job and loading of the needed raid module. How does it work: - If a an array is defined on users system /etc/mdadm.conf, the file will be added to initramfs and used for the assembling things. - If no array was defined it falls back to commandline assembling and a madm.conf file will be created on the fly during bootup. Old command line syntax wasn't changed, uuid support is added (eg. md=0,0900878d:f95f6057:c39a36e9:55efa61b) Attention: Tested normal raid 1 setup with and without mdadm.conf modified. Not tested yet uuid assembling from commandline and partitionable raid! Will test this soon, if an other dev wants to test, please do so :) please signoff, greetings tpowa -- Tobias Powalowski Archlinux Developer & Package Maintainer (tpowa) http://www.archlinux.org tpowa@archlinux.org

How do I test this, and or use this rather than the [raid] hook? Can you show an example mkinitcpio.conf HOOKS line? -Dan

My x86_64 raid system booted fine. It has a modified /etc/mdadm.conf and use RAID5.

My x86_64 raid system booted fine. It has a modified /etc/mdadm.conf and use RAID5. Dan if you use simple raid hook just replace it with mdadm.
If you want to change to a mdadm.conf assembling run as root: # to get just running md devices mdadm -Ds >>mdadm.conf # detecting by superblock mdadm -Es >> mdadm.conf If you use normal command line assembling you don't need to change anything and just replace raid with mdadm in /etc/mkinitcpio.conf to test this. mkinitcpio -p kernel26 and it should work. I replaced my command line assembling with mdadm.conf one, it's much cleaner now :) greetings tpowa -- Tobias Powalowski Archlinux Developer & Package Maintainer (tpowa) http://www.archlinux.org tpowa@archlinux.org

I just realized that I was using the raid hook. I'll test the mdadm one later.

I tested the mdadm hook with modified mdadm.conf. System booted fine.

Worked good for me after a reboot, and I like not having to hardcode anything on the GRUB line anymore. Is this going to be documented somewhere, such as in the default mkinitcpio.conf? -Dan
