When upgrading the kernel I get:
/usr/sbin/grub-probe: error: cannot find a GRUB drive for /dev/sdam1.
Check your device.map.
Auto-detection of a filesystem of /dev/sdam1 failed.
Please report this together with the output of "/usr/sbin/grub-probe
--device-map=/boot/grub/device.map --target=fs -v /boot/grub" to
<bug-grub@gnu.org>
/dev/sdam is clearly (hd13). The rest of the drives are a software RAID60.
Can I force GRUB to install on /dev/sdam1 (hd13) without probing?
