[Lustre-discuss] Help: NIC Changed Error

[Lee Amy]

Hi,

I'm a Lustre newbie. The server I set up is combined MGS/MDT file
system on a block device. And set up OST on a block device. I set up
MGS/MDT and OST in the same machine by using 2 disks. The NID is
10.0.38.102 at tcp, and the address 10.0.38.102 was assigned to eth0. One
day I noticed the eth0 is broken so I use another NIC eth1 then assign
IP address 10.0.38.102 to this card.

Then I use client the mount the server Lustre FS by following command.

mount -t lustre 10.0.38.102 at tcp:/ericlfs /mnt/foobar

It reported following error messages.

Lustre: Request x1310428982411274 sent from MGC10.0.38.102 at tcp to NID
10.0.38.102 at tcp 5s ago has timed out (limit 5s).

communication errors between this node and the MGS, a bad
configuration, or other errors. See the syslog for more information.

So I feel a little confused. Is this problem caused by I replace the
NIC card? And furthermore, how do I fix that problem?

Thank you very much.

Best Regards,

Amy
