<p>Folks,<br>
<br>
We are scheduled to make the move of our work space from a
Lustre-based system to a ZFS file system. This will happen
tomorrow (Wednesday, November 29) starting at 9 am. The move
should take about an hour.<br>
<br>
N. B.: <b>during this time, you will not be able to write to
the Hall D work disks</b>. Reading may be intermittent as
well.<br>
<br>
Some notes on the new configuration:<br>
<br>
Both /work/halld and /work/halld2 will be on the same partition.
The old /work/halld2 will actually appear as a new directory,
/work/halld/halld2. A merge of the two systems is not a
practical option. There will be a soft link, /work/halld2
pointing to the new /work/halld/halld2 directory, so legacy
scripts should work.<br>
<br>
Since there will be no distinction in the underlying hardware
for the old /work/halld and /work/halld2, there is no more need
to distinguish how they should be used. Small files and SQLite
files are OK anywhere on the new work disk.<br>
<br>
To reduce future confusion, you may want to move your files out
of /work/halld/halld2, but that is not required at present.<br>
<br>
Any scripts that use<br>
</p>
<p> /lustre/expphy/work/halld or /v/lustre2/expphy/work/halld</p>
<p>instead of</p>
<p> /work/halld</p>
<p>or that use<br>
</p>
<p> /w/halld-scifs1a</p>
<p>instead of</p>
<p> /work/halld2<br>
</p>
<p>will break. In other words, the server-specific directory names
will change (as they must).<br>
<br>
Let me know if there are any questions or objections to this
schedule.<br>
<br>
- Mark<br>
