Hi,
My LVM2 volume just stopped working out of the blue. I added a new disk to
the volume group a while ago and added it to a logical volume, and used
xfs_growfs to extend the partition.
All off a sudden a few weeks later, it stopped working. Upon reboot I get
this error message:
device-mapper: device /dev/hdd1 too small for target
device-mapper: dm-linear: Device lookup failed
device-mapper: error adding target to table
I have alot of important data on these disks, are there any way to get the
volume up running again, or get some data back from any of the individual
disks? The problems seems to be on the /dev/hdd disk. I've tried searcing
in google, but havent found anything specific about a problem like mine.
I run gentoo with the 2.6.13-gentoo-r5 kernel.

# vgscan
Reading all physical volumes. This may take a while...
Found volume group "vg" using metadata type lvm2
pvscan and vgscan appears to run fine, but when I try to activate the
volumegroup, I get the following error:
# vgchange -ay
device-mapper ioctl cmd 9 failed: Invalid argument
Couldn't load device 'vg-public'.
1 logical volume(s) in volume group "vg" now active
(and when I do this, the device-mapper also logs the 3 error lines I
pasted earlier in this mail again)
Below are the outpots that pvs, vgdisplay and pvdisplay give me
