Hello all,
To keep everyone abreast of the churn in the athena.dialup pool, I'm in
the process of decommissioning three of the eight Suns to be reclaimed
into the Linux pool. Those are:
all-night-tool
no-knife
scrubbing-bubbles
The first is already off and I will power off the other two this
afternoon, now that two days have passed since I have nologin'ed them.
I'm in the process of removing them from the dialup name pool so that it
will stop knowing about these three in general.
I have set up two of the four hypervisors in OC11 where the new dialups
will live and breathe freely. We're in the final stages now of getting
them flying. I should have the other two in place by the end of next
week. If all goes well, I should have the replacements for these first
three dialups in place by the end of today. Again, they will *not* be in
the athena.dialup pool, so users can't just accidentally fall into them by
going to that name. They can, however, wander into them by deliberately
going to them directly or by going to the soon-to-exist linux.dialup name,
which will run in parallel. If people deliberately go to these, I kinda
feel like they can handle a Linux environment (I'll update their motd
accordingly), but I can also nologin these as well after they're built. I
have no real stake either way.
Linux.dialup will run for some time in parallel while we get the other
hypervisors in place. If, after a couple of weeks, there are no issues,
we'll replace cvp, i90, and hotd with Linux counterparts, leaving the
existing doa, bl5, and brym servers to remain for those wishing to
continue using Suns until the demise of that platform. At that point,
I'd like to switch athena.dialup to point to the Linux servers rather than
the Suns.
Sound like a plan? I think so. Yell if there are any questions or
obvious errors.
