One of the changes, pleasantly, is that it finally understands things like software RAID internally to grub, so that sort of issue is much reduced.

RE: [SLUG] Re: GRUB2 + RAID-1 on debian?
Hi Ian, I have no experience with Debian, RAID-1 (software) and Grub, but I use it on numerous "low end server" Fedora installations. Make sure you install a copy of the grub boot loader in the master boot record of each hard drive, otherwise a failure of Disk0 will result in a machine that does not boot from the Disk1 mirror. This site/article shows how to install grub to the 2nd hdd: http://lists.us.dell.com/pipermail/linux-poweredge/2003-July/008898.html While this one shows the hdd replacement method to rebuild your arrays: http://www.howtoforge.com/replacing_hard_disks_in_a_raid1_array I hope this helps avoid future heart ache.

[SLUG] GRUB2 + RAID-1 on debian?
Hi, I've been trying to migrate my PC to RAID-1 on debian (testing), and it's up and running but update-grub and grub-install fails, I could just edit grub.cfg by hand but that's not ideal. I've got /dev/md0 (sda1, sdb1) --> /boot /dev/md1 (sda3, sdb3) --> / $ update-grub grub-probe: error: no such disk. $ grub-install /dev/sda grub-probe: error: no such disk. I tried to replace grub-probe with a wrapper to see what it was doing, and essentially it fails on $ grub-probe --device /dev/md0 --target=abstraction grub-probe: error: no such disk. and $ grub-probe --device-map=/boot/grub/device.map --target=fs --device /dev/md0 grub-probe: error: no such disk. I think it's konking out because /dev/md0 is a software raid-1 device. Anyone ever encounter anything like this before and know the way around it?

Yeah I second Ken's reply to this - Windows has exactly the same problems at the moment. Especially with Windows 7 64bit. I have clients that have sound card problems that are unresolvable because the driver doesn't support Win7 properly. Others have all sorts of other issues getting things to work - webcams, fingerprint readers, extra stuff. Its not roses on the other side either...

Installed windows on non-mainstream machines lately. You have to find drivers, have conflicts of dlls and other things. I am not saying that it is not a problem, just not doom and gloom. It is worth bearing in mind that Microsoft once did deals with Hardware suppliers and Hardware suppliers basically had/have to comply.However, the take home message from Jon's experience is the was a driver out there, so the manufacturers are obviously on board (difficult to write drives without the specs). However, one of the issues is licensing. WiFi as we all know is a licensensed technology, with royalties flowing through to CSIRO. Similarly for DVD/MPEG2. However, my understanding is that in both these cases the license is in the hardware not the software or at least not at the operating system/driver level. Alternatively, if the hardware ships with a license for the Windows software this should be transferable for use in the Linux software - as the Windows software and embedded license is redundant. A couple of years back, I bought a digital TV tuner that only came with a Windows driver with a view to running it under linux. I subscribed to the list and learnt a bit about what was involved. One of the issues seemed to be the hardware supplier was not keen for the specs to get into the public arena.So, the linux community may need to make do with closed source drivers.

To the community. Jon's experience probably really demonstrates why Linux isn't going to go mainstream anytime soon. While I would say 90% of people are going to have hardware that just works with the most current release of most distros, it is the 10% that have issues that really stings. Surely this hurdle needs to be overcome. With the likes of Canonical, Redhat, Novell and the like wanting this to work surely there is a need for some sort of integration centre that hardware vendors can submit their gadgets for driver development assistance, and qualification?
