Ok. Could you try "verbose" now as the log level? It is close to the
"all" level but should only print information while the server is busy.
Are both wn140 and wn141 showing the same batch create errors, or just
one of them?
thanks,

Hello Phil,
Thanks for you answer.
Yes I delete the storage dir every time I make a new configuration
and I run the pvfs2-server -f command before starting the daemons.
The only thing that I get from the servers is the batch_create, starting
server, and the "PVFS2 server got signal 15 (server_status_flag: 507903"
error message. Do you want me to try on an other log level?
Also, this is how the server is configured:
***** Displaying PVFS Configuration Information *****
------------------------------------------------------
PVFS2 configured to build karma gui : no
PVFS2 configured to perform coverage analysis : no
PVFS2 configured for aio threaded callbacks : yes
PVFS2 configured to use FUSE : no
PVFS2 configured for the 2.6.x kernel module : no
PVFS2 configured for the 2.4.x kernel module : no
PVFS2 configured for using the mmap-ra-cache : no
PVFS2 will use workaround for redhat 2.4 kernels : no
PVFS2 will use workaround for buggy NPTL : no
PVFS2 server will be built : yes
PVFS2 version string: 2.8.1
thanks again,

Hello,
I'm not sure what would cause that "Invalid argument" error.
Could you try the following steps:
- kill both servers
- modify your configuration files to set "EventLogging" to "none"
- delete your old log files (or move them to another directory)
- start the servers
You can then send us the complete contents of both log files and we
can go from there. The "all" level is a little hard to interpret
because it generates a lot of information even when servers are idle.
Also, when you went from one server to two, did you delete your old
storage space (/pvfs) and start over, or are you trying to keep that
data and add servers to it?
thanks!

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:*

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,
