Is that OFED 1.1? Does /etc/modprobe.conf contain...
options lnet networks=o2ib
...or the equivalent using ip2nets? If this isn't clear, please see the
lustre manual for an explanation of network setup.
Can you bring up lustre networking on the mgs and a client node...
modprobe lnet; lctl net up
...and then check /proc/sys/lnet/nis? It should list the local NIDs (e.g....
<ipoib IP address>@o2ib
[EMAIL PROTECTED]
...). If that looks OK, run an lnet ping from the client to the MGS...
lctl ping [EMAIL PROTECTED]
Please note that by default, network error messages are logged internally, but
are not printed to the console or /var/log/messages,
so it may help to "echo + neterror > /proc/sys/lnet/printk" to enable verbose
network messages while you are debugging connectivity.
Cheers,
Eric

Subject: [Lustre-discuss] [Lustre-devel] Using Infiniband with 1.5.95
We're trying to set up a Lustre configuration using infiniband ipoib with
1.5.95. openib 1.1 (was formally openib gen 2) is
installed. We can successfully ping between the mdt/mgs nad ost servers using
the ipoib address. Lustre fs creation is "apparently"
successfull. Mounting the lustre device fails.
1. Does 1.5.95 work properly with ipoib?
2. What is the proper form of mgsnode specification, should o2ib or openiib
be used?
2.a Should we specify the ipoib address or the adapter/port #?
The ost command line we're trying is:
mkfs.lustre --fsname=testfs [EMAIL PROTECTED] /dev/sdb1
