Emergency maintenance: Arya

UPDATE: The time for maintenance has changed to 17:30 The server will go offline at 17:25

The Hetzner datacentre has informed me that the RAID alarm for the server Arya is currently sounding.

This means that either one of the hard drives has failed and requires replacing, or that something has gone wrong with the RAID configuration.

I have scheduled emergency maintenance for 5PM this afternoon, 25 January 2017.

The server will go offline at 4:55PM and should be offline for no longer than 40 minutes while the technicians work on it.

I will ensure that a full server backup is made before the server goes offline, to ensure that no data is lost.

Your emails will not be affected in any way as they are hosted on a separate mailserver.

Please accept my sincere apologies for any inconvenience this may cause you.

Arya: Emergency maintenance

10 February 2016

8:00 Arya is back online. Performance will be degraded (sites will be slow) while the RAID rebuilds for the next hour or so.

7:15PM The server is being shut down now.

7:10PM Backup has completed

5:15 Starting a full server backup now

5PM Hetzner has just informed me that the RAID alarm for the server Arya is sounding.
This means that either a hard drive has failed (and requires replacing) or there is something wrong with the RAID configuration.
I have given them the go-ahead to take the server offline to diagnose and fix the problem.
I expect up to 30 minutes of downtime while they do this, for which I apologise.
