[lustre-discuss] ZFS Support For Lustre

[Hans Henrik Happe]

Hi,

The repos, in general, only work for the kernel they were build for. 
This will be the supported kernel by the release. Look in the changelog. 
For 2.15.1:

https://wiki.lustre.org/Lustre_2.15.1_Changelog

To make newer kernels work you have to compile yourself and that might 
not even work without patching and hasn't gone through testing.

You are better of following the supported kernel on the servers. The 
client is usually more likely to compile/work on newer kernels, but 
patching might be needed.

Cheers,
Hans Henrik
