<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>You might want to grep it for your username if you are
wondering if you have any files at risk.</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>
