Migrating developer.pidgin.im

[Mark Doliner]

Our hosting provider, NetworkRedux, will be moving "imperial," the
virtual machine that hosts developer.pidgin.im to different hardware
that will hopefully perform better for us.  The scheduled time for
this migration is 10:00AM PDT on Wednesday of this week.  If anyone
suspects there will be problems with this, or if you think it would be
better if the scheduled time was changed, please let me know.

This should not affect "rock," the virtual machine that hosts
http://pidgin.im/, mtn.pidgin.im, these mailing lists, is our primary
mail server, and is our primary DNS server.

I don't forsee this being a major problem, but I will be unavailable during that
time (from about half an hour prior until at least 8 hours afterward), so I
won't be able to assist if services need restarting or any other administration
is necessary.  It's probably best if at least one person with the requisite
access *is* available just in case.

I also cannot be available during business hours.

I am also not available, I'm out of town all this week.  That said,
Thomas is going to most likely attempt an online migration, which copies
the running memory and and CPU state across between the servers so
there's no reboot or service interruption.  If this is done and
succeeds, there should be no need to intervene.

I'll make an attempt to be available.

De we expect it to be relatively instantaneous?

The migration runs in the background and we shouldn't notice anything
but the second to last hop of the traceroute changing when the target
machine receives the memory dump and CPU state.

The machine appears to be inaccessible (I can't SSH to it, nor is the
d.p.i website up).

d.p.i is responding for me now and things seem to be working, but the
uptime is 53 minutes, so I suspect it was rebooted with an offline
migration.  The resource usage is nice and low now, so presuming
everything is operating, trac and friends may be feeling much better. :)

In the gap of time between when I wrote the message and sent it (I got
interrupted), it looks like it started working :)

False alarm.

Thanks,
