Re: [lustre-discuss] SSK key refresh issue

There is nothing I can think of off the top of my head that would be a limiting factor preventing SSK from working with multiple file systems. Unfortunately my test environment is unavailable to look at this right now. If you can send some server logs I can take a look although I suspect Sebastien

Re: [lustre-discuss] SSK key refresh issue
