[EMAIL PROTECTED] ~]#
Then when I try to mount it on client node I get following problem:
[EMAIL PROTECTED] ~]# mount -t lustre [EMAIL PROTECTED]:/datafs /mnt/datafs
mount.lustre: mount [EMAIL PROTECTED]:/datafs at /mnt/datafs failed:
Input/output error
Is the MGS running?
the IP address is OK and it is pingable from the client node.
[EMAIL PROTECTED] ~]# ping storage01
PING storage01.storage.cluster (10.143.245.1) 56(84) bytes of data.

Client node has LNET entry in modprobe.cfg for the right eth
interface.
options lnet networks=tcp0(eth0)
Why it isn't working?
cheers

Hi,
I have a following command line:
mkfs.lustre --fsname datafs --ost [EMAIL PROTECTED] /dev/sdb
Does --mgsnode above is correctly specified if MGS resides on the
same node that OST?
Host-name of the node is storage01 and modprobe.conf contains
following line: options lnet networks=tcp0(eth0)
That looks correct.
