Re: Re: /etc/fstab error and I can't start the system normally

[micman]

I think that the problem was a damaged  system. I have re-installed 
FreeBSD  and now ALL the commands and methods work.


mount -u /
or
mount -o rw /
and I can access to the root directory

I mount /usr and I can use ee  (effectively a nice editor)

ee /etc/fstab (absolute path isn't necessary)

I have tried  Fixit and the result  is the same (here the absolute 
path is NECESSARY).


For a non-experimented user --like me-- cover the bases is the most 
important thing to begin.  I couldn't rescue my old system but now I 
know a little more.


Thank you very much.

  get into a console maybe by booting single user.
  remote root as read/write you may or may not have to
  remount root as write but...

  mount -u /
  ee /etc/fstab

  fix the error hit [esc] cc [esc] a and you should be
  good to go. 

  hope that helps

I have tried. Result:

can't exec mount -u / for single user: No such file or directory
and
ee: not found

About ee in the FreeBSD command reference I have tried this:
This is a simpler alternative to 'vi' and is installed as part of the FreeBSD 
base system. However it may not always be available (there
is /rescue/vi for emergencies when /usr is not mounted, but no emergency 'ee').

I have tried 'vi': not found

But in my /rescue 'vi' is listed and I have this message:
no terminal database found

  You  can  go  to  single  user  mode  (4)  from  the  boot  menu  and  then  
 mount  -  
  o  rw  /  .  Then  you  can  edit  /etc/fstab.

I have tried. Result:

can't exec mount -o rw / for single user: No such file or directory
