Thanks Brian. I was wondering what will happen during OST failure - if client is making some read/write operation - if client requests read/write after OST fails
When I made OSS unavailable the client waited/got delayed response till OSS connected back. I am not sure about OST failure though. Any clues? - CS. On Thu, Jun 25, 2009 at 10:34 AM, Brian J.
