We have received notification of another failed drive on the Titan server this time being on the same port as a drive that was replaced just recently. This is pretty rare thing to happen so we believe it be best to replace the raid card. It has also been throwing various errors and emails us events suggesting it's just not right. This could be due to the power issue a while ago or this card could have been faulty for some time and it just took us seeing two drives on the same port fail within a short while.

We will be doing this as soon as possible the current estimate is we'll be replacing the card at about 9:45AM PDT and the machine should be down no more than 20 minutes. We're very sorry about the short notice regarding this but when the raid card is acting strange we rather replace it as soon as possible then avoid possible data loss.

Just a small correction some delays we'll be doing it around 10:00am PDT and it'll be down for about 15 minutes is our estimate assuming nothing bad happens. Once the server is back up we'll still replace the one hard drive but that will be non service impacting.

The drive has now been replaced.

Just a further note we did not just replace the raid card but also the cabling as well. It's just a normal measure taken with anything to do with the raid cards. We always replace anything that could potentially have caused issues.
