Hello, I successfully build lustre(1.6.4.2) on my system for a patchless client But I dont know how to proceed in configuring the file system.
I'm trying to build all MDS,client and MDT's on a single node. >From the tutorials I came to know that First, create an MDT for the "spfs" file system that uses the /dev/sda disk. This MDT also acts as the MGS for the site. $ mkfs.lustre --fsname spfs --mdt --mgs /dev/sda But by triggering this command my system crashed in which the whole data is lost and again I need to install the OS. I want help in proceeding of mounting a lustre file system.

After switching to dual 10g and creating a new filesystem (1.6.4.2), I'm seeing nothing but keep-alive packets with bad checksums. What is the current "correct" way to do this now? The manual suggest not using bonding, but several list postings now reccommend it. Without bonding, do I need to have my 2 switches stacked, or will Lustre recognize the division in my subnet? LNET module options I've tried are: 1) networks="tcp0(eth2,eth3)" 2) ip2nets="tcp(eth2,eth3); tcp(eth2) 10.9.[1-4].*; tcp(eth3) 10.9.[5-8].*;" and many other variations All other services are functional on both interfaces.
