[HPDD-discuss] Testing, Diagnostic and Debug tools for Lustre 2.4

Hello All, I am looking for some testing, diagnostic and debugging tools for Lustre 2.4. I have 3 node setup up and running where one node is MGS/MDS, 1 node is OSS and another one is client. I am able to make the file system and mount the file systems on MGS and OSS and also able to mount MGS on Client. The only way I know this is running successfully as I do not receive any error. Can someone suggest me tools or methods for Test the setup, diagnose the setup and debug the configuration? Thanks, -Upanshu Upanshu Singhal EMC Data Storage Systems, Bangalore, India.
