[Pvfs2-developers] Problem with PINT_cached_config

[Bradley W Settlemyer]

Hello

   I'm having a problem with detecting the number of IO servers -- it 
doesn't make any sense.  Here is a program sample:

bradles at speed:~:71> software/pvfs2/bin/pvfs2-cp pvfs2.patch 
/parl/bradles/software/pvfs2/mnt/foo.3
BWS: num_io: -1075277896
BWS get_num_io: 1
BWS - num_dfiles: 1
bradles at speed:~:72>

I've added debug statements to the calls to 
PINT_cached_config_get_num_io_servers and PINT_cached_config_get_num_dfiles

As you can see, the number of IO servers returned by 
PINT_cached_config_get_num_io_servers is -1075277896??

To reproduce, copy a file larger than 64KB into a multiserver PVFS2 file 
system and see if it places any data on the second server.  It should. 
Otherwise the number of dfiles has been set to 1, even though it should 
be 2 (at least according to my knowledge of PVFS2).

Is it possible I've screwed up my config files somehow?  I've attached 
them, just to be certain.

Cheers,
Brad
