Dear All, Please ignore this request of mine. I misinterpreted my actions and scripts, and had a panic attack on something silly as lfs command not working because I had other oss down. What a relief!! Although I continue to have some performance problems on this specific OSS OST's, even mounting OST's took unusually longer time, and writes are on about 45MB/s where as other OST's on other OSS's are at 300-350MB/s. I will persuade the performance problem tomorrow hope I can find a way to dig into this.

At this point I have deactivated all OST's on this OSS server. I am not sure on how to recover or clean this up to get the OST back to production use. Any insight or help will be greatly appreciated. Thank you, Amit
