Hi Jian,
It appears that you have a misconfigured network. "No route to host"
is an IP networking error. I would try using UNIX tools like ping and
ssh to ensure that you can connect from host2 to host1 and vice versa.
You could try putting the IP address of the hosts in place of the
"host1" and "host2" in your config file, as another option.
Also, it would be better if this discussion occurred on the pvfs2-
users mailing list. If are a member of the pvfs2-users list, please CC
that mailing list in your reply. And please attach your /etc/fstab and
PVFS configuration files, and note what version of PVFS you're
attempting to install.
Thanks,
Rob

Hi,
I try to install pvfs2 in two nodes, host1 is metadata server and
both of the two hosts are data servers.
But when I use pvfs2-ping to test it, both host1 and host2 gave the
same error.
The output is below. Could anyone tell me where I'm wrong.
Thank you.

Exactly one server must own the root handle.
In this setup, no servers own the root handle.

The PVFS2 filesystem at /mnt/pvfs2 appears to have problems.
