Hi,
I could successfully mount a gfs partition and export with gnbd. It was
also very fast, when I was moving a file from the client to the server,
but if I try a second operation, like copying the file back, it always
hangs. I can not even do copy files locally to the gfs partition anymore.
Unfortunately, there is no info at all in the syslog or any other logfile.
And the "gnbd_import -vl" and "gnbd_export -vl" don't show any error
either. I guess it has something to do with the locking or fencing, but I
don't understand that very well. Below it my config etc. Thanks for any
hints!!

I exported/imported the file system like that:
gnbd_export -d /dev/hdd1 -e testgfs
gnbd_import -i eon
mount -t gfs /dev/gnbd/testgfs /mnt/gfs1/
