When installing some updates on a Debian Squeeze box, I received a grub error:
error: unknown LVM metadata header.
error: unknown LVM metadata header.
Generating grub.cfg ...

/usr/sbin/grub-probe: error: no such disk.
It seems it’s a common bug on grub 1.98 version. The quick (and dirty) way of getting rid of it was to install the “unstable” grub update :
- add the “unstable” repo :
- vi /etc/apt/sources.list
- add :
deb http://debian.mirror.iweb.ca/debian/ sid main
deb-src http://debian.mirror.iweb.ca/debian/ sid main
- apt-get update
- apt-get install grub-common
- comment out the lines you just added in /etc/apt/sources.list and apt-get update again…
Everything is now working fine.
