Hello all,
I have been trying to install PVFS 2.8.1 on Ubuntu server, Centos4 and
Scientific Linux 4. I compile it and can run it on a "single host"
configuration
without any problems.
However, when I add more nodes to the configuration(always using the
pvfs2-genconfig defaults ) I have the following problem:
*On the metadata node I get these messages:*
[E 04/02 20:16] batch_create request got: Invalid argument
[E 04/02 20:16] batch_create request got: Invalid argument
[E 04/02 20:16] batch_create request got: Invalid argument
[E 04/02 20:16] batch_create request got: Invalid argument
*In the IO nodes I get:*

The metadata node keeps asking for something that the IO nodes cannot give
the right way. So it complains. This makes the nodes and the metadata node
not to work.
I have installed those services many times. I have tested this using
berkeley
db 4.2 and 4.3 on Redhat systems(centos, scientific linnux) and on Ubuntu
server.
I have also tried the PVFS version 2.6.3 and I get the same problem.

My setup is made from two nodes that are both IO and Metadata nodes. I have
also tried
a 4 node setup with 2I/O - 2 MD nodes resulting in the same thing.
Any suggestions?
thank you in advance,
