Specifically,</div><div><br></div><div><ul class="MailOutline"><li>Users writing to /mss/home/___ directories that do not logically belong to them. For example, user 'bob' will be denied write permission to /mss/home/alice.</li><li>Users writing to /mss/___ directories that are logically closed to new data. For example, a directory created for an experiment that ended years ago.</li><li>Users writing to /mss/___ directories for whom there is no longer any clear owning unix user.</li></ul><div><br></div><div>Judging by access patterns over the past three years, only a very small number of users are likely to notice any impact.</div><div><br></div><div>Read permissions will not be affected.</div><div><br></div><div>If you suspect that these changes will affect you, please feel free to contact us (<a href="mailto:scicomp@jlab.org">scicomp@jlab.org</a>) for assistance.</div><div><br></div></div><div>Thanks,</div><div><br></div><div>Chris</div><div><div><div>
