Bug#473532: grub-probe: error: Cannot get the real path of `/dev/scsi/...'

[Vincent Danjean]

Package: grub
Version: 0.97-35
Severity: important

  Hi,

With the new package grub 0.97-35, when update-grub is launched
(manually or by installing a new kernel package), I got:

Running postinst hook script /usr/sbin/update-grub.
Searching for GRUB installation directory ... found: /boot/grub
grub-probe: error: Cannot get the real path of
`/dev/scsi/host0/bus0/target0/lun0/disc'
User postinst hook script [/usr/sbin/update-grub] exited with value 1

If I run manually 'grub-probe /', I also got this error.

In fstab, I have:
/dev/mapper/cayuga-root /       ext3    defaults,errors=remount-ro 0 1


In /boot/grub/device.map, I had
(hd0) /dev/scsi/host0/bus0/target0/lun0/disc

I workaround this problem, I removed /boot/grub/device.map:
rm /boot/grub/device.map
and then reinstall grub:
grub-install /dev/sda

/boot/grub/device.map then contains:
(fd0)   /dev/fd0
(hd0)   /dev/sda

At this point, I suffer from bug #473209
So, I remove the first line in /boot/grub/device.map (the line with fd0)
and then all seems good for me.

  Best regards,
    Vincent

PS: I set severity important because this bug breaks kernel upgrade
(and it is not very easy to know how to recover)
