[Lustre-discuss] Help with problem mounting Lustre from another network

Hello,

Could somebody please give me some hint on this?

This is my first trying with Lustre. I installed everything on
a single node following the Lustre quick start:

http://wiki.lustre.org/index.php?title=Lustre_Quick_Start

with the new version 1.6.5. When I mounted the client
on the same node, everything works fine. 

Later, I tried to mount the client from a seperate network. I
got the following error:

>mount -t lustre 128.227.89.181 at tcp:/testfs /mnt/testfs

mount.lustre: mount 128.227.89.181 at tcp:/testfs at /mnt/testfs
failed: Cannot send after transport endpoint shutdown

The error message from the server side is:

Jun 18 19:52:04 olivine
kernel: LustreError: 5682:0:(socklnd_cb.c:2166:ksocknal_recv_hello()) Error
-11 reading HELLO from 128.227.221.35

scontext=system_u:object_r:unlabeled_t
tcontext=system_u:object_r:netif_eth0_t tclass=netif

This is the result using lctl:

>lctl ping 128.227.89.181 at tcp
failed to ping 128.227.89.181 at tcp: Input/output error

This is the related configuration of /etc/modprobe.conf from both client
node and server node (MDS+OSTs):

# Networking options, see /sys/module/lnet/parameters
options lnet networks=tcp
#    (the llite module has been renamed to lustre)
# end Lustre modules

The server's ip address is: 128.227.89.181
The client's ip address is: 128.227.221.35

They are on two different network.

Thanks in advance for any help you give.


Regards,
Yujun
