Re: [linux-lvm] snapshot file zombies



Jürgen,

those are Reiserfs errors telling that the filesystem isn't able to
search an entry by key. Could well be an io error on the snapshot LV but
then we should have a related entry in the syslog.

If you are able to read the snapshot fine (for eg. with 
(dd if=/dev/SNAPSHOT of=/dev/null bs=1024k), I assume a reiserfs error.

If reading the snapshot LV fails, let's go forward analyzing LVM, if not
there might be a reiserfs fix for that.
