Can you ping (the regular UNIX utility) from the clients to the server?
This really looks like a TCP routing problem.

Hi Rob,
pvfs2-ping works fine on server1 itself, but failed on both client1 and client2.
Even using IP address in the /etc/pvfs2tab file does not help.
The pvfs2 version is 1.3.2, the latest release, from
ftp://ftp.parl.clemson.edu/pub/pvfs2/pvfs2-1.3.2.tar.gz.
The detailed information is shown as below.

From server1, on which PVFS2 works, the results is:
[EMAIL PROTECTED] ~]# pvfs2-ping -m /mnt/pvfs2

Ok; root handle is owned by exactly one server.

The PVFS filesystem at /mnt/pvfs2 appears to be correctly configured.
From client1, with 2.4.20-8 kernel:

I tried both hostname and IP address, the pvfs2-ping gives the same results.
For hostname, the content of the /etc/pvfs2tab file (the same on all
the three machines) is :
tcp://server1:3334/pvfs2-fs /mnt/pvfs2 default,noauto 0 0
For IP addresses, the content is:
tcp://129.93.164.223:3334/pvfs2-fs /mnt/pvfs2 default,noauto 0 0

Hi,
Can you "ping" between the various machines using those same names?
Does pvfs2-ping work with those hostnames? Does it work with IP
addresses? What version of PVFS2 is this?
At least the second error looks like a networking problem.
Thanks,
Rob

When I tried to mount the pvfs2, I got the error: "mount: No route to host".
The detailed information is as follows:
I have three Linux machines altogether, namely server1, clients1 and client2.
server1 serves as both metadata server and I/O server. All the threemachines
are clients, including the server itself.
The problem is, I managed to mount the pvfs file system on the server1,
however,I failed on both client1 and client2.
The kernels for the three machines:server1: 2.6.9-5ELsmp with
Fedoraclient1: 2.4.20-8 with Redhat 9client2:
2.6.9-5ELsmp with Fedora
On client1, when I type,mount -t pvfs2 pvfs2 /mnt/pvfs2 -o
tcp://server1:3334/pvfs2-fs
the outcome is:pvfs2_get_sb -- wait timed out (ec0001). aborting
attempt.pvfs2_get_sb: mount failed with 15466497mount: Invalid argument
On client2, when I type,mount -t pvfs2 tcp://server1:3334/pvfs2-fs /mnt/pvfs2-fs
the outcome is:mount: No route to host.
Any suggestion is appreciated!
Peng
