No I'm afraid not.
Will you be able to be more specific per host? Can you
also let us
know what counts as the afternoon of the 11th (I'm assuming 12:00 - 17:30)?
There are 6 hosts to work on and I'll start about 13.30 GMT. I
expect it will take 2-4 hours in total.
Just want to make sure I'm properly prepared for
the outage :)
Also - will we need to shut down our hosts before-hand, or will that be done
as part of the maintenance?
They will be suspended to disk and then restored afterwards so to
them it will be similar to a networking outage. Suspend/restore
hasn't been 100% reliable in the past however so you may want to
ensure that your VPS boots with all services you need running
starting from boot, just in case.
Also when suspend/restore does work it tends to play havoc with the
clock causing ntpd to give up time syncing. So you may want to log
in when it's back to fix the clock and restart ntpd if necessary.
Nagios can monitor your ntpd if you ask for it.
Cheers,
Andy
