<p>Folks,</p>
<p>I made a listing of the 5,000 largest directories on
/volatile/halld_old, inclusive of subdirectories. Find it at</p>
<p>
<a class="moz-txt-link-freetext" href="https://halldweb.jlab.org/disk_management/volatile_halld_old.txt">https://halldweb.jlab.org/disk_management/volatile_halld_old.txt</a></p>
<p>You might want to grep it for your username if you are wondering
if you have any files at risk.</p>

<p>Folks,<br>
</p>
<p>A reminder: all files on /volatile/halld_old will be deleted in
nine days, on Wednesday, March 4. See item 4 in the procedure
below.</p>
<p>There is still quite a lot of data in /volatile/halld_old.
People should check that they do not have anything important
there.<br>

<p>Gluons,</p>
<p>Our volatile disk space is moving to a newly purchased Lustre
system. I mentioned this at the last Software Meeting. In the
end our space will double from 70 TB to 140 TB. This will also
give us independence from LQCD Lustre.</p>
<p>Recall that volatile is not backed up and <a
moz-do-not-send="true"
href="https://scicomp.jlab.org/docs/volatile_disk_pool">files
are subject to deletion when it gets full</a>, just as
before.</p>
<p>The transition will start on Tuesday, February 4. And it goes
like this (please note step 4):</p>
<ol>
<li>/volatile/halld will be renamed as /volatile/halld_old.
All files and directories will be preserved other than the
change to the name of the top level directory. Files can be
read from and written to the renamed location.<br>
</li>
<li>A new directory will appear on the new system named
/volatile/halld (what else?). It will be empty, no
directories, no files. This is our new volatile space.<br>
</li>
<li>We can now use the new space in any way we like. An
example of a likely use is to copy the contents of
/volatile/halld_old/foo/bar to /volatile/halld/foo/bar. Such
actions will not happen automatically. SciComp requests that
we delete the contents of /volatile/halld_old/foo/bar after
such a copy is done, but deletion is not required.</li>
<li>After a month, all files remaining on /volatile/halld_old
will be deleted.<br>
</li>
</ol>
<p>Hall B is in the process of going through this now, FYI.</p>
