I don't think there's a real use case to have both available on the same server. This solves many issues of how to structure dependencies especially for zfs build (and the build dependency issues inherent in dkms when rebuilding for a new kernel).</p> <p>I don't see a simple way to ONLY build osd-zfs.ko or ONLY build osd-ldiskfs.ko so I didn't break the osd portions out, but the new dkms packages will be lustre-modules + lustre-osd-zfs or lustre-modules + lustre-osd-ldiskfs, or lustre-modules + both osd's.</p> LU-9761

IML requires that all storage servers (a.k.a. Lustre servers) support both ldiskfs and zfs because IML needs to be able to scan the system for targets of both types and doesn't know ahead of time which it might find.</p> <p>Sorry, I copied and pasted the description, I've been around on this with Chris, and the patch actually crates 3 separate server dkms options, ldiskfs, zfs and all.</p> <p>I am kind of surprised why do we need ldiskfs dkms when lots of people oppose having full build environments on every node. On zfs there's at least soem value for patched servers case because we cannot distribute binaries, but ldiskfs?</p> <p>I would guess it's because some people would accept having full build environments on nodes in exchange for having a hands-off distro-kernel upgrading procedure.</p> <p>Patchless server gives you that upgrading procedure. For project quotas patched kernels there is always a manual kernel building step.</p> <p>Minh Diep (minh.diep@intel.com) uploaded a new patch: <a href="https://review.whamcloud.com/31201" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/31201</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-9761" title="Add ldiskfs support to dkms for patchless kernel" class="issue-link" data-issue-key="LU-9761"><del>LU-9761</del></a> dkms: Add ldiskfs dkms support<br/> Project: fs/lustre-release<br/> Branch: b2_10<br/> Current Patch Set: 1<br/> Commit: fd03941dee71753e0ec05e18fb221e74500a2186</p> <p>John L.
