A DegradedArray event had been detected on md device /dev/md2.

Faithfully yours, etc.

As this server does not have a hot-swap disk backplane, we will use the necessary short period of downtime to move the server within the office server room into our rack.

This maintenance will happen late one evening this week, and should have little effect on customers.
