Hi,
Great news, thanks a lot. The samples now mount without error, altough the processes do not exit after umount. This is no problem for me, but if it needs fixing, tell me what information you need.
Thanks a lot (again).

Greg Milliam figured this out. Apparently the fuse API changed a bit in
the latest version (you are using the latest fuse?). I went back to a
previous fuse version, and then everything worked.

I am having this exact same probem. fuse's examples work, but all the examples in the sample directory produce:
# ruby /usr/share/doc/fusefs-0.4/sample/hello.rb tmp/
fusermount: mount failed: Invalid argument
/usr/lib/ruby/site_ruby/1.8/fusefs.rb:13:in `for_fd': no implicit conversion from nil to integer (TypeError)
from /usr/lib/ruby/site_ruby/1.8/fusefs.rb:13:in `run'
from /usr/share/doc/fusefs-0.4/sample/hello.rb:20
I've poked around in it a bit, but my understanding of C is very limited and I don't get any closer to a solution... Any help would be greatly appreciated.

OK, well, I'm glad I'm not just crazy. Err... Well I guess we haven't proved that yet..
Anyway, printing ARGV[0]
1017$ ./hello.rb /mnt/test
fusermount: mount failed: Invalid argument
/usr/local/lib/site_ruby/1.8/fusefs.rb:13:in `for_fd': no implicit conversion from nil to integer (TypeError)
from /usr/local/lib/site_ruby/1.8/fusefs.rb:13:in `run'
from ./hello.rb:21
/mnt/test <======= looks OK.

This does look odd, and it works for me as well.
Try printing out ARGV[0] to make sure it's what you think it is? I don't see any reason it would be anything other than the first arg you pass (/mnt/tmp) unless you're calling this in some other way.

Hi Greg,
(1) /mnt/test is a directory.
1004$ ls -ld /mnt/test |drwxrwxr-x 2 root rpeterso 4096 2005-10-04 15:28 /mnt/test/
(2) /mnt/test isn't mounted. I did 'fusermount -u /mnt/test' also.
1006$ grep test /etc/mtab | wc
0 0 0
(3) fuse module is loaded. (I first statically linked fuse into the kernel, and got a module missing error.)
1007$ lsmod | grep fuse
fuse 29196 0
(4) Vitals
Pentium4 (Dell Latitude C840)
Debian Sarge
Tried FUSE 2.4 (from source) and Sarge's fuse-utils and libfuse2 packages (2.2.1). Since they both behaved the same, I'm back to 2.4 from source.
FuseFS 0.4
Ruby 1.8.2
I just ran the 'hello' example in the fuse source distribution's examples directory as me, on directory /mnt/test, and it worked o.k.
Here's my exact hello.rb. Are there any ruby library dependancies I might be missing? I don't have the whole kit-n-kaboodle installed. I'd think that would throw a different kind of error, though.
(I've done this w/out inheriting from FuseFS::FuseDir also, per the shipped example..)
Best.
#!/usr/bin/env ruby
require 'fusefs'
class HelloDir < FuseFS::FuseDir
def contents(path)
['hello.txt']
end
def file?(path)
path == '/hello.txt'
end
def read_file(path)
"Hello, World!\n"
end
end
root = HelloDir.new
FuseFS.set_root(root)
FuseFS.mount_under(ARGV[0])
FuseFS.run

Some ideas from what's caused this in the past:
1) Make sure /mnt/test is a directory
2) Is /mnt/test is already mounted? If you ran a fusefs script on it earlier and killed it such that it couldn't unmount itself, your system likely still thinks it's mounted. Try running: "fusermount -u /mnt/test" to unmount it.
3) Is the 'fuse' module loaded in the kernel? FUSE consists of two portions: the kernel module and the library. FuseFS uses the library (-lfuse) and requires the kernel module to be insmod'd
4) Failing all of the above: What CPU (x86, amd?), Linux distro, FUSE, FuseFS and Ruby versions do you have?
Hope that helps,
- Greg

Hi,
FuseFS looks very cool. I've installed 0.4 on debian sarge. I'm running linux 2.6.14-rc3.
When I run hello.rb, I get the following error:
999$ ./hello.rb /mnt/test
fusermount: mount failed: Invalid argument
/usr/local/lib/site_ruby/1.8/fusefs.rb:13:in `for_fd': no implicit conversion from nil to integer (TypeError)
from /usr/local/lib/site_ruby/1.8/fusefs.rb:13:in `run'
from ./hello.rb:21
(yeesh, line wraps might look horrible...)
I've tried running as root, and as myself. I have permissions to write to the mountpoint. I don't have nosuid on the filesystem where fusermount lives, or anything like that.
Any ideas? TIA.
