<p>Folks,</p>
<p>Recall that during the transition of /work/halld to a new
server a couple of weeks ago, /work/halld3 was left alone.
SciComp is now ready to move /work/halld3 to a subdirectory of
/work/halld3. Links will be installed so that the path
/work/halld3 will continue to find the same files as it did in
the past, but the physical location of those files will have
changed. And any path starting with /w/halld-sciwork18, which
does work now, will not work after the transition (it may
resolve to a read-only file system at first before disappearing
permanently).<br>
</p>
<p><b>The cut-over will happen between 9 am and 10 am
(approximately) Thursday, September 2 (day after tomorrow)</b>.
During this time the files on /work/halld3 will be unavailable.</p>
<p>One technical point: the majority of files have already been
transferred to their new home. The outage is to transfer files
that will have recently appeared on the old server to the new.
At that point write access to the old server will be removed so
that no more new files are created. To make this final transfer
go faster, we want to minimize the volume of "new" files on the
old server. So for the next couple of days, before the switch,
please try to limit the volume of new files being written to
/work/halld3. Said another way, please refrain from dumping
multi-terabyte datasets to /work/halld3 until after the
transition. <br>
