For log directory permissions, just make sure the root log directory has read+execute permissions set for anyone who will be creating logs in it. The 'darshan-mk-log-dirs' will make sure all the subdir permissions are correct.

I just had to try it out to remind myself, but 'darshan-mk-log-dirs' does currently expect the root log directory (i.e., the log path you passed to '--with-log-path' config argument, '/usr/local/darshan-logs' in your case) to be already created outside of the
script. That is a little confusing given the name of the utility, in that you'd probably expect it to gracefully handle the case where the root doesn't already exist... I just created an issue to ensure we make the errors more clear in why the script fails,
and will probably also just modify the script to create the root if it doesn't exist -- I don't see any reason why it shouldn't already be doing that.<br>

<div>Thanks for the reply! I apologize for not thinking of the need for the existence of the root directory - I should have caught that.</div>

<div>Oops - one quick question. What permissions do you recommend for the root directory?</div>

<div>Good afternoon,</div>
<div><br>
</div>
<div>I have a small problem when I build Darshan. It doesn't create the log directory, so I used the script
<a href="http://darshan-mk-log-dirs.pl" target="_blank">darshan-mk-log-dirs.pl</a>. However, I get an error:</div>
<div><br>
</div>
<div># ./<a href="http://darshan-mk-log-dirs.pl" target="_blank">darshan-mk-log-dirs.pl</a><br>
Error: could not mkdir /usr/local/darshan-logs//2020.<br>
</div>
<div><br>
</div>
<div>This is an Ubuntu system I used sudo to run the script and I also tried as root. In either case, I get the same result.</div>
<div><br>
</div>
<div>While I can follow the Perl script (it's been a few years since I last coded in Perl), I want to make sure I track down the cause of this error.</div>
<div><br>
</div>
<div>Thanks!</div>
