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


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 on ns1 and move it to ns2
  2. Disable 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 back over to ns1 and re-enable it the network config

For ns2, I’ll do the same steps but moving its IP ( 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!
