All the raid disks I have are used, active and clean. The disk which is out of the raid doesnt have a syperblock [EMAIL PROTECTED] % sudo mdadm -E /dev/sda1 mdadm: No md superblock detected on /dev/sda1. >GRUB and grub-probe use the superblock directly they find on the disk. >Even grub-probe doestn't use at all the informations from the > assembled >RAIDs it could get from kernel (for example /proc/mdstat) > >If this doestn't solve your problem then please do a debug compile >with: >apt-get build-dep grub2 >apt-get source grub2 >DEB_BUILD_OPTIONS=nostrip,noopt,debug dpkg-buildpackage -b >You may need a `deb-src' line in /etc/apt/sources.list for this. >It's just the same as the `deb' one, just with `-src' Ok, done. > >grub-probe is in grub-common >To get the core file you need to do `ulimit -c unlimited' first. > >I don't know where the core file then be placed but maybe it just >segfaults ifyou just run `grub-probe /' >Then you should have a `core' file in your current directory. >Else do `find / -name "*core*"' > >Would be very good if you would forward this to [EMAIL PROTECTED] > (but >you need to subscribe first) and the /usr/sbin/grub-probe else the >corefile is useless.
