I've made a mistake today.
I was trying to modify l2arc_write_max and l2arc_write_boost.
What i did was: CAREFUL THIS IS WRONG
it should be
Reboot resulted in some error that said zfs module couldnt be loaded and there are invalid parameters...
My root is ony the ZFS.
Here is what I did to recover my system:
Press "i" to change to insert mode, edit the faulty lines and save the file via (ESC) -> :wq
Then I rebooted the machine and it worked again.
I hope this helps. I dont want to reproduce this right now to double check, but I think this was what I did.
