firewall blocking port 3334? if you're familiar with tcpdump or
ethereal, you could use one of those tools to look at the network
traffic.

Attached is the config file and fstab file in host1.
I can ping each other from either host1 or host2. I can also ping
the hostname too cause I set this up in system-administration-
network in FC.
Thank you.

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
