Thank you for your information. That's really helpful.
This time I try both 3334 port. OpenSUSE-desktop is OK this time, but the
server on suse64 can not be started.
on both machine, I ran
# netstat -tan | grep 3334
I got
{tcp 0 0 0.0.0.0:3334 0.0.0.0:* LISTEN
}
on both.
And the /tmp/pvfs2-server.log on suse64, on which can not start the server,
showed:
{PVFS2 Server version 2.7.0 starting.
[E 01/23 13:44] Error: BMI_sockio_bind_sock: Address already in use
[E 01/23 13:44] Error: tcp_server_init() failure.
[E 01/23 13:44] Error: BMI_initialize: Address already in use
[E 01/23 13:44] Error: Could not initialize server interfaces; aborting.
[E 01/23 13:44] Error: Could not initialize server; aborting.
}
Does it mean, I can not assign port 3334 to both of them? Or, maybe starting
the servers on both machines exactly at the same time will help?

Hi,
When you run your netstat check to see if anything is using port 9000,
you should probably run it with these arguments:
netstat -tan | grep 9000
The "-n" part of the netstat command line is important to make sure that
you get numerical port numbers rather than symbolic names for them. The
"-t" makes it only show tcp ports, which are the only ones that matter
to PVFS.
IANA indicates that port 9000 could possibly be used by something called
"cslistener". If opensuse happens to include that in their
/etc/services file then you would see <host>:cslistener rather than
<host>:9000 when checking netstat without the "-n" argument, and the
grep would miss it.
