Re: [Cooker] raidstuff+install
Same old problem. Mandrake has been doing this as long as I can remember. RAID should not be dependent on raidtab to start. In fact, there are plenty of circumstances where one might have a raidtab that is inconsistent with your actual setup. RAID should be started by default using autorecognition based on partition type. The stuff in the init scripts should, at most, be a fallback, where autorecognition has failed to start arrays. Even then, there should probably be some means to indicate that this is what you want to do, rather than just doing it by default, as you might have wanted to temporarily disable the array by changing the partition type. You don't really want to have to edit your raidtab to decide which arrays will or won't start. I pointed out this (and problems with mkraid during beta3 install) a week ago, but it doesn't seem to have grabbed anyone's attention. Basically, Mandrake could solve their RAID failings once and for all if they would just build RAID (at least 1 and 5) support into their default kernels. Of course, there are other ways of doing it, but no one seems to have figured out how to do it in a more complicated way without breaking various setups. Building RAID into the kernel would cut the Gordian knot. Cheers, Bruno Prior Oden Eriksson wrote: torsdagen den 20 februari 2003 13.57 skrev Oden Eriksson: Hi.

what do you mean? can you tell more?
Check: http://archives.mandrakelinux.com/cooker/2003-01/msg08314.php
(speaking to myself again...)
To clarify:
The old md's I had and which were discovered during install was originally
mounted /var/qmail/queue (md0) and /home (md1). I configured them to
mount /mnt/md{0,1} during the install phaze. But the raidtab generated
contained only:
raiddev /dev/md2
device /dev/hdd5
This caused boot failure.
I also tried to configure after boot with diskdrake, but that didn't work
either. I'm staging a machine from old hw right now and I have no time to
reproduce and document what was going on. Maybe I could do it tomorrow (on
another hdd) when this install is done.

Put it a two-line config where there should have been something like 4 r 5 md devices. This was a 9.0 install onto two 120GB IDEs, plus an existing raid1 on two 40GB IDEs. IIRC, none of the RAID devices worked after boot, luckily we had the root not on RAID, so we booted, fixed the raidtab manually, and then raidhotadd'd them.
