Lustre is a novel storage and filesystem architecture and implementation suitable for very large clusters. It is a next-generation cluster filesystem that is currently running on clusters that have tens of thousands of nodes, petabytes of storage, and move hundreds of GB/sec.

This release adds support for downgrading pools-striped files. Distribution kernel support has been updated to RHEL5 kernel-2.6.18-92.1.10.el5 and SLES10 SP2 kernel-2.6.16.60-0.27. There are numerous bugfixes, including fixes for 8 TB systems with more than 65536 groups, machines with more than 1GB of RAM, and issues when mounting filesystems with the flock option.

I'm in dire need of help. I've been assigned with this task and I have very little time and knowledge of lustre. Here's what I need to accomplish:
4 OSS's (connected to DDN controllers via 4gb fiber)
1 MDS/MGS
and 30 clients
The server hardware is as follows:
ibm e326 servers with infiniband (ib) cards

I attempted to follow the lustre manual but I'm failing at configuring lnet. I installed all the proper rpms however and added the following line to modprobe.conf:

options lnet networks=tcp0(ib0)

can someone confirm this line is correct? The infiniband interface is ib0 and we're using IP.

Secondly, what do I need to do to configure the MDS/MGS? I ran mkfs.lustre on my /dev/sda and it fails stating that it is in use by the system. Do need to create a partition? what size should I make it. If anyone out there can help I would really appreciate it!

Thanks!
