We will have a scheduled maintenance window tonight from 7:00pm to 11:00pm PDT. The following changes will take place:

  • 7:00pm PDT (0200 UTC) TryServer maintenance. Release Engineering will be resetting the hg repo being used under TryServer. See bug 491092 for details. Duration 15 minutes.
  • 7:00pm PDT (0200 UTC) VM datastore migrations. In preparation for an upcoming EqualLogic firmware upgrade, we’ll be moving several VM’s underlying datastore to another iSCSI array. See bug 491767 for details. No downtime is expected but we’re doing this during this window in case there are issues with storage vmotion. The list of VMs/hosts that will be moved are:
    • production-master
    • try-master
    • try-win32-slave01
    • try-win32-slave02
    • try-win32-slave03
    • graphs.mozilla.org / dm-graphs01
    • build.mozilla.org / dm-wwwbuild01
    • geodns01.sj.mozilla.com
    • pm-ns03 (LDAP slave)

Please let me know if you have any reason why we should not proceed with this planned maintenance. As always, we aim to keep downtime to as little as possible, but unexpected complications can arise causing longer downtime periods than expected. All systems should be operational by the end of the maintenance window.

Feel free to comment directly in those bugs if you see issues past the planned downtime.
