[dm-devel] device-mapper: device /dev/hdc too small for target



Hello,
I'm encountering some problems with device-mapper when migrating my lvm system to a new debian system. I must say I had to play around with pvcreate and vgcfgrestore to get /dev/hdb recognized again on the new system but after fixing that issue I'm stuck with following problem: Booting the new system with the lvm disks it seems that the device-mapper is having troubles putting together the lvm device:

output from dmesg:
device-mapper: 4.1.0-ioctl (2003-12-10) initialised: dm uk sistina com
device-mapper: device /dev/hdc too small for target
device-mapper: : dm-linear: Device lookup failed

device-mapper: error adding target to table

Starting the lvm service gives the following:
storage:~# /etc/init.d/lvm start
Setting up LVM Volume Groups...
Reading all physical volumes.  This may take a while...
Found volume group "storage" using metadata type lvm2
/dev/storage: opendir failed: No such file or directory
device-mapper ioctl cmd 9 failed: Invalid argument
Couldn't load device 'storage-storage1'.
1 logical volume(s) in volume group "storage" now active
storage:~#

Nevertheless other lvm commands seem to display correct information about the lvm. Below is the output from pvscan, lvscan, lvmdiskscan, pvdisplay and vgdisplay. The lvm is appearing in the /dev/mapper folder, but no link is made in the /dev folder btw. Mounting the lvm fails, gives the error of bad superblock (ext3 filesystem). The lvm has been created using the full disks and not working on partitions. I'm hoping someone on this list can help me out or give me some pointers on how to continue and getting the disks right and making my lvm mountable again.
Thx in advance,
Thomas.
