Planned down time for some group space

We have several terabytes of new disk space to attach to our SAN. Unfortunately this will mean shutting down the disk array ifevo3 to do the work.

The data on ifevo3 is nearly all group space, plus some of our system/backup data. While ifevo3 is down, the group space listed below will be unavailable.

To do this work without affecting other files and home directories served by the same servers, we will need a brief interruption to all files served by the those servers. Once before the work starts, and once again after it is complete. These brief breaks should last no longer than 2 minutes, you may not even notice them at all.

We are planning to do the work on Friday 14th of August, between 9am and 10am. Please let us know now if this is going to cause you real problems.

The list of group areas that will be unavailable during the work is:

    This went to plan, and the affected group areas were back just before 10am.
