One of the disks of our RAID array started failing last week. The server can still run with one disk down, but this put us at the risk of loosing data if one more disk failed. So replacing that disk became a priority. Instead of just replacing the faulty disk, we decided to replace all the drives. This improves reliability overall and since we bought bigger disks, as a side effect it also doubles our storage capacity.
And this is not the end of the story: instead of installing the disks on the old server, Julien installed them a slightly faster spare machine. This should give use slightly better performance, but more importantly the new 2 U rack-mounted server now fits much more nicely in our rack.
The server was down Sunday and during part of the night from Sunday to Monday (Pacific Time) to allow for this upgrade.
