Subject [Hosting] {ns1, ns2}.osuosl.org RAID firmware upgrade Aug 8, 2017 10:30AM PDT (1730 UTC)

All,

I need to perform a RAID firmware upgrade on both ns1 and ns2 tomorrow at
10:30AM. This upgrade is required to resolve an issue we ran into as
described in this CentOS bug [1]. I plan to to the steps described in this
comment [2] to resolve the issue.

Here's my plan for the upgrade:

1. Bring down 140.211.166.130 on ns1 and move it to ns2
2. Disable 140.211.166.130 from coming back up on ns1 during the upgrade as
I require several reboots
3. Do the upgrade tasks as described in [2].
4. Once the fix is validated, move 140.211.166.130 back over to ns1 and
re-enable it the network config

For ns2, I'll do the same steps but moving its IP (140.211.166.131) to ns1.
This should cause minimal downtime and outages for anyone using our DNS
servers.

If you have any questions or concerns please let me know.

Also, just a friendly plug and reminder that our crowd funding campaign [3]
has 16 days left!

Thanks-
