Re: [lustre-discuss] latest kernel version supported by Lustre ?

Thinking on this a little bit more I think James Simmons has been looking at newer Ubuntu versions than 16.04 so he should be able to comment further. On 2018-04-09, 6:52 AM, "Jones, Peter A" > wrote: Ah sorry about that– I was reading
