Re: fuse problem

[huang jun <hjwsm1989@gmail.com>]

unfortunately, i tried all what you have told me, but no one
works.there still nothing
in /home/client_logfile:
     huangjun:/mnt# ll /home/client_logfile
     -rwxrwxrwx 1 root root 1 2011-05-19 20:57 /home/client_logfile
but i think this is not so seriously, i have a problem confused me a lot.
i list what i have done
1) [root@localhost /]# cfuse  -o nonempty -m 192.168.0.11:6789 /mnt/
      ARNING: bsdocfs inode numbers are 64 bits wide, and FUSE on
32-bit kernels does
         not cope well with that situation.  Expect to crash shortly.
