Hi, On a debian squeeze server configured with multipath-tools and multipath-tools-boot for boot on san, update-grub fails with the message /usr/sbin/grub-probe: error: cannot find a GRUB drive for /dev/mapper/mpath0-part1. Check your device.map.
I tried to modify the device.map file, but I always got the same error. note : I installed dmsetup package from sid on this server to solve the uuid problem describe here http://lists.alioth.debian.org/pipermail/pkg-lvm-maintainers/2011-February/003472.html any help would be very welcome regards, Rémi -------------------------------------------------- $ update-grub Generating grub.cfg ... /usr/sbin/grub-probe: error: cannot find a GRUB drive for /dev/mapper/mpath0-part1.
