[linux-lvm] kernel: zam-7001: io error in reiserfs_find_entry

[Jürgen Vollmer]

Hi everybody,

I use kernel-source-2.4.16.SuSE-24.i386.rpm together with reiserfs and
made a snapshot which I then tar'ed.
Writing the tape seems to be ok. After that I did:

	tar --directory=/ --file=/dev/tape --compare

and got the message (while working i.e. modifying the  original filesystem)

So it seems that the snapshot is full. Is that correct, or do I have a serious
problem? Note: I'm doing my backups, so a dead backup is not a very good
one :-)

With best regards
