Re: raid autodetect problem
hi christian if you have a raid-root-fs, then i think the problem is that the kernel cannot load the modules unless the rootfilessystem is mounted and /lib/modules/ is available. but without the module, a mount is not possible. :-o have you tried with compiled in support ? ps: nice to see an another austrian on the list :-) mfg mrq1 Christian Bucher wrote: I just installed a raid with autodetection. During that I found a (I think funny) problem which I want to report. kernel 2.2.17pre13-RAID pre-patch-2.2.17-13.bz2 raid-2.2.17-A0 raid1 was configured as module, the vmlinuz image is located in a /boot partition. It looks like the module is requested before mounting the root fs which makes naturally trouble. 3request_module[md-personality-3]: Root fs not mounted Maybe it would be helpfull to add this case to the RAID-HOWTO. ciao christian -- +--- | Christian Bucher | phone: +43 1 5488640 mobil: +43 699 1 4208334 | mailto:[EMAIL PROTECTED] +--- -- linux 2.2.16 on a dual pentium iii 500 512mb Total of 2 processors activated (1992.29 BogoMIPS). 4:10pm up 4 days, 2:38, 1 user, load average: 2.11, 2.11, 2.23

Re: raid autodetect problem
i have also some add-ons for the howto: i have mailed them to michael, but i got no answer :-( again my points: 1) at 4.4 Copy the current OS to the new raid device you should add a hint for creating a empty boot and proc directory, my rh6.1 box hangs after the first reboot with the floppy, "unable to mount proc" 2) in the new /mnt/x/etc/fstab should be all mounts (except / and /boot) be marked with a #, i wait for the fsck of my 15gig disc 20 min :-(( when everything works, the marks can be removed and the system is in the original state 3) before permanently switching to the raid as root device, the /mnt/x/etc/lilo.conf should be altered to the root=/dev/mdx option, and for the permanently switching only the command: /sbin/lilo -C /mnt/x/etc/lilo.conf is need 4) write a info, that the mainstream kernel has a option for raid, but this option is not the required one as big as possible !!! ;-) with the link to redhat-patch 5) write a info about the partition id's, i missed what the required option is (before i know, that it is not relevant, of course), after all it should be set to "fd" mfg mrq1 -- linux 2.2.16 on a dual pentium iii 500 512mb Total of 2 processors activated (1992.29 BogoMIPS). 5:10pm up 4 days, 3:38, 1 user, load average: 2.25, 2.20, 2.18
Re: raid autodetect problem
You could probably make it work OK by using initrd and loading the module with the script, but compiling in support would be much more straightforward.
