<div><br></div>2.<span style="white-space:pre-wrap"> </span>Unmount+remount or otherwise refresh disks involved? Could this be a glusterfs configuration thing? I just learned of glusterfs a minute ago, after running below commands. I see root dir (/) for imc.naf is rasputin's /naf , which is a little different from configurations I'm used to, so I may be off on the basic concept here...</div>

<div><br></div><div><br></div></div><div><br></div><div>3.<span style="white-space:pre-wrap"> </span>Turn it off and on again. That is, simplest but most severe: Restart <a href="http://imc.naf.chambana.net/" target="_blank">imc.naf.chambana.net</a> as well as the associated file server rasputin. Power both down, then power rasputin back up first. Plus, if any other machine is running apache2 or serving needed files and I haven't realized it, similarly restart those too. Uptime on imc.naf is 68 days. Experience from NFS: Sometimes, with a stale NFS handle, and maybe with other confusion based on moved mount points, only solution is to restart the machine. (I suppose restarting NFS should work, but if if you going to go that far anyway, might as well restart or <span style="white-space:pre-wrap"> </span>power cycle.)<span style="white-space:pre-wrap"> </span></div>
<div><span style="white-space:pre-wrap"> </span></div><div>4. Make sure we know which machine is serving web queries. In all of above approaches I'd try to access <a href="http://thebikeproject.org/" target="_blank">thebikeproject.org</a> web site while the targeted machine/service/file system was unavailable. That is, when apache2 is not running on imc.naf, for the few seconds when <a href="http://imc.naf.chambana.net/" target="_blank">imc.naf.chambana.net</a> was powered down, or when all apache2 processes are verified killed, try to browse <a href="http://thebikeproject.org/" target="_blank">thebikeproject.org</a>, to make sure some other server independent of imc.naf isn'y somehow serving the page.</div>
<div><br></div><div>5. It's looking a little like there is more than one apache2 instance serving thebikeprojectorg files. One responds to web queries with week-old pages, and is not logging to access and error logs. Another seems to respond to one or two accesses a day and is logging to access and error logs (there should be hundreds of log entries, including the handful of test accesses I've been generating each day, but there are only two or so each day in</div>
<div> /home/barryi/tbp-logs/thebikeproject.org-access_log</div><div>). I don't know if the latter apparent instance is serving old or new pages. This would be less confusing if there were _no_ log entries each day in access/error logs, but each day a couple appear -- and they are not the test accesses that I make. Could this point to some recently switched-around IP numbers / DNS server changes? </div>
