See mkfs.lustre(8)</p> <p>We attempt to set hostid by using /sbin/genhostid, we confirm the ID exists, same failure. We attempt to set hostid by /usr/bin/hostid, confirm the ID exists, same failure<br/> At this time we cannot format OSTS, system is dead.</p> LU-8694

ZFS format fails when /etc/hostid is set or unset.

Bug Critical Resolved Fixed Nathaniel Clark Cliff White Tue, 11 Oct 2016 16:39:00 +0000 Thu, 13 Jul 2017 00:51:22 +0000 Tue, 25 Oct 2016 04:10:07 +0000 Lustre 2.9.0 Lustre 2.9.0 0 5 <p>Nathaniel</p> <p>Can you please help improve the docs here?</p> <p>Peter</p> <p>The fix is simple - reload the SPL module after creating /etc/hostid. Nathaniel will be updating the documents. We are able to format now.</p> <p>This mostly means that we should change the mkfs.lustre message to indicate the spl.ko module needs to be reloaded (or better yet, try to unload it and reload it internally once), and improve the mkfs.lustre.8 man page to prefer running <tt>genhostid</tt> over spl.ko module parameters, and indicate that the spl.ko module needs to be reloaded after generating a new hostid.</p> <p>Nathaniel Clark (nathaniel.l.clark@intel.com) uploaded a new patch: <a href="http://review.whamcloud.com/23118" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/23118</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-8694" title="ZFS format fails when /etc/hostid is set or unset.
