lctl does not support listing nodemaps

Bug Minor Resolved Fixed John Hammond John Hammond nodemap patch Wed, 5 Nov 2014 16:22:24 +0000 Wed, 10 Jun 2015 19:51:49 +0000 Wed, 10 Jun 2015 19:51:49 +0000 Lustre 2.7.0 Lustre 2.8.0 0 7 <p>Kit, could you take a look at this?</p> <p>Sure, it doesn't look like I can assign this task to myself, but I'll work on adding a command. At the moment, there is the hack of looking in /proc/fs/lustre/nodemap to see what directories exist, but I agree it should have a real command.</p> <p>Would it be enough to map this command internally to essentially be <tt>lctl list_param nodemap.*</tt> or similar? No point in making it too complex if there isn't a requirement for it.</p> <p>Kit, any progress on this?</p> <p>Hi Andreas,</p> <p>Nothing substantial, I'll work on it for Tuesday. I started looking into using list_param. It looks like there is no way to ask list_param to only show directories, so it adds all the add_idmap, etc proc files. Would it be worth adding a flag to list_param to only list directories? Or should I just send an ioctl to get the nodemap list?</p> <p>Kit Westneat (kit.westneat@gmail.com) uploaded a new patch: <a href="http://review.whamcloud.com/13044" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/13044</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-5868" title="lctl does not support listing nodemaps" class="issue-link" data-issue-key="LU-5868"><del>LU-5868</del></a> nodemap: Add nodemap_info to lctl<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: 1<br/> Commit: 5d803680bdc7aadd852e3124d334c41cffa94340</p> <p>I wrote a small patch that currently doesn't list, but it does display other information.
