[Resolved] xn3 outage

xn3.pcsmarthosting.co.uk currently has issues with the RAID controller which we are working to resolve. Further updates will follow.

Update: We’ve traced this to a bug in the upstream Linux 4.9 kernel. The raid controller and array appear to be healthy. We’ll bring the server back up on a secondary kernel to restore service. Further investigations will be carried out in our test environment.
