sounds like your client can connect to the mogilefsd tracker but not the
mogstored nodes.

What happens when you "open" a file is the client connects to mogilefsd,
which gives the client one or more http urls that point to your
mogstored nodes.  So it looks like your client is getting that list, but
is unable to connect.

try using mogtool with debugging on to get more information:
$ mogtool --debug --trackers= --domain=foo --class=bar  inject /etc/motd /etc/motd
or such

Make sure that your clients can connect to the mogstored nodes on port
7500 and 7501....
