[lustre-discuss] Lustre 2.10.0 ZFS version

[Cowe, Malcolm J]

The further complication is that the Lustre kmod packages, including kmod-zfs-osd, are compiled against the “lustre-patched” kernel (3.10.0-514.21.1.el7_lustre.x86_64), rather than the unpatched OS distribution kernel that the ZoL packages are no doubt compiled against. The move to patchless kernels for LDISKFS (which more or less works today, provided you don’t need project quotas) will further simplify binary distribution of the Lustre modules.

Malcolm.

    To be clear - we do not _currently_ build the Lustre RPMs against a binary RPM from ZoL, but rather build our own ZFS RPM packages, then build the Lustre RPMs against those packages.  This was done because ZoL didn't provide binary RPM packages when we started using ZFS, and we are currently not able to ship the binary RPM packages ourselves.
    
    We are planning to change the Lustre build process to use the ZoL pre-packaged binary RPMs for Lustre 2.11, so that the binary RPM packages we build can be used together with the ZFS RPMs installed by end users.  If that change is not too intrusive, we will also try to backport this to b2_10 for a 2.10.x maintenance release.
    
    Cheers, Andreas
