Lustre releases are tested against the next higher/lower release for clients/servers, as well as the previous LTS release. In this case, 2.10 and 2.12 are expected to work together without issues. While it is possible for a wider range of versions to interoperate (e.g. some people have tested/used 2.5 and 2.10 together), we do not test this due to limits on our testing resources. > The alternative is to keep using the 2.6.99 vintage Lustre kernel modules > that come with kernel.org kernels with the 2.10.x software.
