These services all run on a virtualized cluster. The cluster storage will be undergoing maintenance that requires all systems to be shut down. We expect the total downtime to be less than 2 hours, but are scheduling 3 in case of unexpected problems.
This is a reschedule of the maintenance of March 12th which was not successfully completed. I have installed some additional patches on the system which should avoid the problem which occurred on 3/12.
If successful, this will be the last time we ever have to do this very intrusive maintenance. Additionally, this will allow us to retire some buggy software on our SAN which has been the cause of previous department-wide storage outages.
