Hi, I have configured Lustre 1.6 beta with OpenIB support, however I couldn''t locate any guide about how to use openib parameter in the mkfs.lustre and client mount command. This is what I have done Add lnet to /etc/modprobe.conf on all nodes # options lnet networks=openib,tcp Then configure lustre with openib support. But I don''t know what to do next in order to use both IB only and IP over IB. On MDT/MGS, what is the correct mkfs.lustre command should be ? I used: #mkfs.lustre --fsname=testfs --mdt --mgs /dev/sda1 The results look like MGS is running over IP over IB rather than IB purely. On OSS, how do I specify openib in the mkfs.lustre command? I used: mkfs.lustre --fsname=testfs --ost --mgsnode=<IP of ib0 on MGS>@openib0 /dev/sda2. I received error after this, it complained connecting to MGS via ib was refused. Replacing with hostname/tcp0 eliminated errors. However, openib is not used then. Similarly, what''s the command on clients to use openib or IPoIB? mount -t lustre ??? :/testfs /mnt/testfs Clients can''t mount at all, always try to connect MGS with ib0''s IP address and fail. I truly need help for enabling both IB only and IPoIB on lustre! (There must be some difference about enabling this two. I couldn''t find either:( Many thanks.
