Subject: Re: /usr/sbin/grub-probe: error: Couldn't find PV pv2. Check your
device.map.
Package: grub-pc
Version: 1.98+20100804-14+squeeze1
Severity: normal
I have a system where updating device.map doesn't make the error go away:
# update-grub
Generating grub.cfg ...
/usr/sbin/grub-probe: error: Couldn't find PV pv2. Check your device.map.
I use mirrored LVM, no mdadm involved.
Running grub-probe manually complains:
# grub-probe -v -t abstraction /boot/grub/grub.cfg
