I configured the mogile file system in two machines using Red Hat EL4
platform. db, tracker and storage are perfectly working without any
problem. Here I used mysql cluster and it also perfectly working.

But I have a problem with client script. Only I can do is creating a
object. I used two types of codings. And here they are..
_object create_


use MogileFS;
my <font color="#ff0000">$mogfs </font>= MogileFS->new(domain => 'testdomain',
                          hosts  => [ '192.168.5.125:6001' ],
                          # only on NFS/disk based installations
                          root   => '/var/mogdata',);
die "Unable to initialize MogileFS object.\n" unless $mogfs;

above part works OK.

_key create

_my $fh = $mogfs->new_file("file_key", "testclass");
die "Unable to allocate filehandle.\n" unless $fh;
$fh->print($file_contents);
die "Unable to save file to MogileFS.\n" unless $fh->close;

this gives the error Unable to allocate filehandle at the 2nd line.

_other code (ruby)

_ # Create a new instance that will communicate with these trackers:
  hosts = %w[192.168.5.125:6001]
  mg = MogileFS::MogileFS.new(:domain => 'testdomain', :hosts => hosts
                              :root => '/var/mogdata')

  # Stores "A bunch of text to store" into 'some_key' with a class of 'text'.
  mg.store_content 'some_key', 'testclass', "A bunch of text to store"

that code gives so many errors

I don't know much about perl scripting. I would like to do the client communication using http. I'll be very thankful if you can send me Most
suitable and bias to working client code for file save to delete.

Thanks

Thusitha A.W.
