[linux-lvm] One cannot read from an lv?

[Geert Jansen]

Hello,

I did some further investigations on the problem of reiserfsck and LVM2 that
I posted to this list a few days ago. The problem is caused by the fact that
seek() and read() on the logical volume in /dev/mapper/ fail! For example,
the command "dd if=/dev/mapper/vg0-tmp" fails to read anything.

What does this mean? How can an fsck ever check a volume in this case?
