at about 3AM I released the 8.0k patch release in the athena cell. As
far as I can tell things are taking the release with out too many
problems. However, we pounded on the network pretty hard. The noc
reported temporarily losing contact with a number of things from
random things on server subnets to w20-cluster-ether. I was thinking
about doing the release at 11PM, but cview said that there were about
100 free suns in public clusters, and I was worried that doing the
release would hose down the relevant fileservers, and it was early in
the night for that. In hindsight we probably had closer to 200 free
public machines when I did the release, so I might have been better
off doing it early. Based on looking disk activity and net activity,
I suspect that the fileservers were taking advantage of their RAM to
do buffer caching, but I can't prove that. It is also worth noting
that sdi did not report anything during the entire release process, do
Id say we were definately bound on bandwith not server speed. This
may be due to the fact that most of our server subnets have both a sun
/os and /srvd on them, on different servers.
The only problem I noticed with the release itself is that for all of
the machines that I saw start the release process, they complained
about not finding /tmp/pids, /etc/inetd.pid and /etc/snmpd.pid as they
started to take the update.
