I have a Dell Inspiron 640m laptop running Debian Etch with the 2.6.18 kernel
It had worked fine for a couple of months but I shut it down last week and it
won't reboot as drops to the initramfs Busybox shell.
The problem seems to be with mounting the root filesystem under LVM2 as grub manages to
load and then after some normal initialisation I get:
Code: Select all
Begin: Running /scripts/local-top ...
ide0: I/O resource 0x1F0-0x1F7 not free.
ide0: ports already in use, skipping proble
ide1: I/O resource 0x170-0x177 not free.
ide1: ports already in use, skipping proble
device-mapper: ioctl: 4.7.0-ioctl (2006-06-24) initialised: dm-devel@redhat.com
Volume group "debianrob" not found
Volume group "debianrob" not found
Done.
Begin: Waiting for root file system ...
Check root= bootarg cat /proc/cmdline
or missing modules, devices: cat /proc/modules ls /dev
ALERT! dev/mapper/debianrob-root does not exist. Dropping to a shell!
It's partitioned into:
/sda2 Grub etx3 /boot partition
/sda5 /tmp swap partition
/sda6 / ext3 debian install
sda6 is the logical volume called debianrob
I can mount the /sda2 and see the Grub ext3 partition but if I try to
mount /sda6 all I see is the empty directories lost+found and rob
I fear that this is because I tried booting with a knoppox 5.1 live cd
and it wrote that data to the /sda6 partition when I tried to veiw it, eek.
Is my data all gone?
I have followed the process for no volume groups being found in the
LVM2 FAQ at
http://dev.riseup.net/grimoire/storage/ ... on_restart
But I had no joy. All I get is "no volume groups found"
The one thing that might have confused Debian is that I had a USB memory
stick plugged into the laptop at power down but I've done that before with
no problems.
Any help appreciated
