Incidentally, I left a clock running in a terminal so that I could see when the box went down if it crashed again. The clock code is:
while [ 1 ] ; do echo -en "$(date +%T)\r" ; sleep 1; done
===Important Moves===
I kept the old versions of mediawiki and wordpress and moved them to /bulk/retired (using yyymmdd dates)
mv /var/lib/mediawiki26082020 /bulk/retired/
mv /bulk/retired/mediawiki26082020 /bulk/retired/mediawiki20200826
mv /var/www/html/blog20200809 /bulk/retired/
