[lustre-discuss] What versions of distros are actually supported?

[Sergey Gorenko]

Hi,

I see inconsistent data in the changelog on the site and in the source tree. For example, the list of supported distros for version 2.10 looks like this:

The Changelog from site http://wiki.lustre.org/Lustre_2.10.0_Changelog
    Server support for kernels: 
        * RHEL 7.3 (3.10.0-514.21.1.el7)
    Client support for unpatched kernels: 
        * RHEL 7.3 (3.10.0-514.21.1.el7)
        * SLES12 SP2 (4.4.59-92.17)

         2.6.32-642.15.1.el6 (RHEL6.8)
         2.6.32-696.el6      (RHEL6.9)
         3.10.0-514.16.1.el7 (RHEL7.3)
         3.0.101-0.47.71     (SLES11 SP3)
         3.0.101-97          (SLES11 SP4)
         3.12.69-60.64.35    (SLES12 SP1)
         4.4.49-92.14        (SLES12 SP2)
         vanilla linux 4.6.7

As you can see the changelog file from the source tree contains a lot more versions of distros. Can someone please explain me the difference? 

Are there any differences in the level of support for distros from the list? For example, some of them are less tested or something else.

Thanks,
Sergey
