The DKMS packages downloaded from the Whamcloud website install without error. But, there doesn't seem to be a way to start the Lustre service. /usr/lib/systemd/system/lustre.service appears to only unmount a filesystem and there is no longer an /etc/rc.d/init.d/lustre</p> <p> </p> <p>We found that removing both lnet.service and lustre.service from /usr/lib/systemd/system/ and recopying /etc/rc.d/init.d/lnet and /etc/rc.d/init.d/lustre from a working Lustre 2.10.3 system allowed us to start the system and mount the OSTs that we created with mkfs.lustre.</p> <p> </p> <p>Creating an MGS/MDS with mkfs.lustre executes and running zpool list reports the expected values. The server is using the in kernel OFED for Mellanox ConnectX 100GBE cards. The packages we installed were: </p> <p> </p> <p>libuutil1-0.7.13-1.el7.x86_643.rpm<br/> libzfs2-0.7.13-1.el7.x86_643.rpm<br/> libzfs2-devel-0.7.13-1.el7.x86_643.rpm<br/> libzpool2-0.7.13-1.el7.x86_643.rpm<br/> lustre-2.12.1-1.el7.x86_643.rpm<br/> lustre-osd-zfs-mount-2.12.1-1.el7.x86_643.rpm<br/> lustre-resource-agents-2.12.1-1.el7.x86_643.rpm<br/> lustre-zfs-dkms-2.12-1.el7.x86_643.rpm<br/> spl-0.7.13-1.el7.x86_643.rpm<br/> spl-debuginfo-0.7.13-1.el7.x86_643.rpm<br/> spl-dkms-0.7.13-1.el7.x86_643.rpm<br/> zfs-0.7.13-1.el7.x86_643.rpm<br/> zfs-debuginfo-0.7.13-1.el7.x86_643.rpm<br/> zfs-dkms-0.7.13-1.el7.x86_643.rpm<br/> zfs-test-0.7.13-1.el7.x86_643.rpm</p> <p> </p> <p>What am I missing here?

Cannot Start Lustre 2.12.1 Server

Previously, RHEL-family installations included the SysV init.d lustre script. This allowed <tt>systemd-sysv-generator</tt> to generate a systemd-managed service for it.</p> <p>That commit introduced a systemd unit file for Lustre, but with none of the functionality (currently, the exec statement only does <tt>ExecStart=/bin/true</tt> , so pools are never imported, targets never started, etc). Systemd will prefer this unit file and there's no SysV file for it to fallback to. Additionally, that unit file attempts a full <tt>lustre_rmmod</tt> on service stop, which should probably only be done within the service stop of lnet. It currently hangs the service on a busy system.</p> <p>Oh good, it's not just me! We tried building from source using the --disable-client flag but ran into trouble building the RPMs afterward then stopped debugging there.We managed to get a working version by copying the init.d script from version 12.0 into the 12.1 init.d area and deleting the systemd service file.</p> <p>Do you think this should be marked as a regression?</p> <p>Nathaniel</p> <p>Can you please investigate?</p> <p>Thanks</p> <p>Peter</p> <p>Reverting <a href="https://jira.whamcloud.com/browse/LU-8384" title="convert startup scripts to systemd unit files for EL7" class="issue-link" data-issue-key="LU-8384"><del>LU-8384</del></a> should be okay.  It would be good to get the systemd compatibility block into lustre sysvinit.</p> <p>Revert of <a href="https://jira.whamcloud.com/browse/LU-8384" title="convert startup scripts to systemd unit files for EL7" class="issue-link" data-issue-key="LU-8384"><del>LU-8384</del></a> for b2_12</p> <p><a href="https://review.whamcloud.com/#/c/34868/" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/#/c/34868/</a></p> <p>Nathaniel Clark (nclark@whamcloud.com) uploaded a new patch: <a href="https://review.whamcloud.com/34869" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/34869</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-12298" title="Cannot Start Lustre 2.12.1 Server" class="issue-link" data-issue-key="LU-12298"><del>LU-12298</del></a> init: Add init info to lustre sysvinit script<br/> Project: fs/lustre-release<br/> Branch: b2_12<br/> Current Patch Set: 1<br/> Commit: 0f8bcefbfcd6858e571ad75a99690240e6c9cf27</p> <p>Nathaniel Clark (nclark@whamcloud.com) uploaded a new patch: <a href="https://review.whamcloud.com/34873" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/34873</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-12298" title="Cannot Start Lustre 2.12.1 Server" class="issue-link" data-issue-key="LU-12298"><del>LU-12298</del></a> init: Add init info to lustre sysvinit script<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: 1<br/> Commit: 7dcc7f13bd978c1f38302715cced9061d71f8899</p> <p>Tested this patch on our TDS at ORNL and it looks like it resolves this issue.</p> <p>Oleg Drokin (green@whamcloud.com) merged in patch <a href="https://review.whamcloud.com/34869/" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/34869/</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-12298" title="Cannot Start Lustre 2.12.1 Server" class="issue-link" data-issue-key="LU-12298"><del>LU-12298</del></a> init: Add init info to lustre sysvinit script<br/> Project: fs/lustre-release<br/> Branch: b2_12<br/> Current Patch Set: <br/> Commit: 6e91b341f3d3d3afeef46e1256e35564f8c9d0d1</p> <p>Oleg Drokin (green@whamcloud.com) merged in patch <a href="https://review.whamcloud.com/34873/" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/34873/</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-12298" title="Cannot Start Lustre 2.12.1 Server" class="issue-link" data-issue-key="LU-12298"><del>LU-12298</del></a> init: Add init info to lustre sysvinit script<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: <br/> Commit: cd8a5f533d9df8aef4976d1a4c741d0f3673dd05</p> <p>Landed for 2.13 and 2.12.2</p> Related LU-8384 Development Rank 1|i00g8v: Rank (Obsolete) 9223372036854775807
