Dear Heinz,
A good new year to you!
I've just some spare time :-)
I created the snapshot as usual and let tar access the files:
for i seq 1 20
do
tar -cvf /dev/null /lvm-snapshot
done
after some time tar produces the following:
tar: /lvm-snapshot/vollmer/.exmh/exmh_addrs: can not stat, permission denied
(message translated by me from german)
During that I did some work on the original (reading email and news, running
some compile jobs, running some seti@home jobs).
It seems to me, that when I modify or delete a file in the original, those
files trigger the problem! (I just modified a Makefile and deleted a file
and the next time tar visits that Makefile and the deleted file
it was flagged with the above error message);
The problem is reproducible.
The files exists and are accessible in the original.
ls -l /lvm-snapshot/vollmer/.exmh/
ls: /lvm-snapshot/vollmer/.exmh/exmh_addrs.bak: no permission
ls: /lvm-snapshot/vollmer/.exmh/exmh_addrs: no permission

The files seem to be in the directory catalog, but not in the filesystem
anymore.
Here the original:
ls -l /home/vollmer/.exmh/

Currently I use a SuSe 8.1 system with the actual (i.e. patch-40) kernel
from ftp.suse.com/pub/people/mantel/next.
I use an SMP System (2 x XENON 2GHz, 1GB RAM) with 4 SCSI devices. Three of
them under control of LVM. As filesystem I use reiserfs
ReiserFS version:
$ mkreiserfs -h
mkreiserfs 3.6.2 (2002)
LVM version:
$lvcreate --version
lvcreate: Logical Volume Manager 1.0.5(mp-v6)

Do you need more information, how can I help to find the problem.
With best regards
Jürgen
