running 7.0 because when I try to load fusefs with this command, kldload
/usr/local/modules/fuse.ko I get the following error:

either, because then that error message is printed on the console.

How did you install the fusefs-kmod was it from a package or did you
build it through the ports system?

The most likely cause of this error is due to the fuse.ko module was
not built against the same source as your kernel.  Rebuild fusefs-kmod
and that should resolve the problem.


Hi all,

this did the trick, thanks!
I rebuild my kernel and had to rebuild that port as well.
Was sure I had done a portupgrade -fa before, but still it
seemed I had to rebuild the port first.

After this, I could start fusefs with the script in rc.d 
and after rebooting it recognized that option as well.

Now I managed to mount my external disk with that as well,
so everything is ok:-)

Thanks again,
