Hi,
This is not a filesystem error. I've tested the entire disk with no
error. However I'm going to see whether this happens on the same file or
not (I have one pool per week day). There is this one volume that is
supposed to be used tomorrow.

It runs on a reiserfs 3.6, which doesn't have this limitation. I've
decided to limit the volume size to 2GB in order to minimize damage in
case of a disk failure.
Thank you and sorry for the posting torrent but I've tried to post this
message as an unsubscribed user to the usenet newsgroup several times
before subscribing. Now I've seen a message regarding the "anti-spam"
delay. :-)
