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 d= enied (message translated by me from german) During that I did some work on the original (reading email and news, runn= ing some compile jobs, running some seti@home jobs). It seems to me, that when I modify or delete a file in the original, thos= e 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 insgesamt 34 -rw-r--r-- 1 vollmer users 11282 2003-01-01 20:03 exmh-defaults= -rw-r--r-- 1 vollmer users 11115 2002-09-25 20:25 exmh-defaults= ~ drwxr-x--- 2 vollmer users 1872 2002-07-06 10:18 exmh-images/ -rw-r--r-- 1 vollmer users 65 2001-01-19 11:09 exmh-shell-hi= story -rw-r----- 1 vollmer users 1564 1999-10-27 23:45 exmhsedit The files seem to be in the directory catalog, but not in the filesystem anymore.

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) Heinz Mauelshagen, Sistina Software 15/07/2002 (IOP 10) Do you need more information, how can I help to find the problem.
