[PVFS-users] unable to mount client

[kenix y]

Hi,

About why there is no port number on the "iod 1" line, I am not sure of the 
reason too, as this is my first time trying to install PVFS.
The situation now is that I have an older version of PVFS that comes with 
the installation of BioBrew. And now I'm trying to remove the old one, 
replacing it with ver1.6.2.

If you do a "ping 10.255.255.254" from the head or the compute node, can it 
ping it?

I was able to "ping 10.255.255.254" from both the head(10.1.1.1) :
PING 10.255.255.254 (10.255.255.254) from 10.1.1.1 : 56(84) bytes of data.
64 bytes from 10.255.255.254: icmp_seq=1 ttl=64 timie=0.355 ms
64 bytes from 10.255.255.254: icmp_seq=2 ttl=64 timie=0.326 ms
64 bytes from 10.255.255.254: icmp_seq=3 ttl=64 timie=0.323 ms

and the compute node(10.255.255.254):
PING 10.255.255.254 (10.255.255.254) from 10.255.255.254 : 56(84) bytes of 
data.
64 bytes from 10.255.255.254: icmp_seq=1 ttl=64 time=0.086 ms
64 bytes from 10.255.255.254: icmp_seq=2 ttl=64 time=0.058 ms
64 bytes from 10.255.255.254: icmp_seq=3 ttl=64 time=0.073 ms

I ran it form both machines.

What's the netmask on the interfaces on the frontend and compute node?

My netmask for the first interface is 255.0.0.0
My subnet mask for head node is 255.255.254.0

Thanks for all the help,
kenix
