We wanted to let you know that we will be conducting emergency maintenance on the Dallas Cloud VPS infrastructure for customers hosted on SAN unit 8 to perform preventative maintenance on a failing member disk on Sunday, Sept 8th 10:00 – 10:30 PM EST.
The maintenance process will require a temporary outage in which we must switch-over from the SAN primary replication unit to the standby secondary unit. In doing so, we will place all affected virtual machines into an in-memory paused state and then un-pause them once the switch-over has successfully taken place. We apologize for any inconvenience, but this is the safest method to perform the required maintenance. In-memory pausing of virtual machines will temporarily suspend disk I/O and will ensure that data integrity is not negatively affected by the maintenance.
The switch-over process is expected to last no more than 15 minutes. During this time, your virtual machine will be inaccessible while in the paused state. Once the virtual machine is un-paused, the server will resume from its last state, uninterrupted, with no reboot or loss of uptime visible to the virtual machines OS or applications.
Those affected by this maintenance should have received an email this afternoon alerting them to the maintenance. Please let our support department know if you have any questions, and we’ll be happy to help.
