build of Lustre dkms fails on both 4.9 and 4.12
So I went back to 4.4

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.

Ah sorry about that– I was reading Andreas’s response rather than Riccardo’s 
original request. Thanks for pointing out my error Patrick. In that case we are 
tracking this less closely and the latest that I am aware of is Ubuntu 16 with 
a 4.4 kernel should work for 2.11. This was not an officially supported option 
but I know that some people have used this.

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

2018-04-08 Thread Dilger, Andreas 
What version of Lustre?  I think 2.11 clients work with something like 4.8? 
kernels, while 2.10 works with 4.4?  Sorry, I can't check the specifics right 
now. 

If you need a specific kernel, the best thing to do is try the configure/build 
step for Lustre with that kernel, and then check Jira/Gerrit for tickets for 
each build failure you hit. 

It may be that there are some unlanded patches that can get you a running 
client. 

Cheers, Andreas
