New search servers

I’m happy to say that we’ve now got extra search servers – a failover pair, in fact, so we’re no longer reliant on a single search server. In fact shortly we hope to bring a third server into the pool too. Not bad considering that, so far, we’ve only ever had one (or zero) search servers.

What this means for you is that searches should be faster. It also means that the future performance of the web site is now more assured than it was before – we’re in a substantially better position to handle extra traffic.

Most of the work was done by Robert Kaye; I only helped to polish off the edges 🙂

Looking for a 48-port 10/100 rackmount switch

We’re still looking for a 48-port 10/100 rackmount switch for MusicBrainz. We’d love to have something like an HP ProCurve Switch 2610-48, but we’re not keen on forking over $800 for it. Do you have an old switch laying around that MusicBrainz could put to use? If so, we’d be glad to give you a … Continue reading “Looking for a 48-port 10/100 rackmount switch”

Do you have an old switch laying around that MusicBrainz could put to use? If so, we’d be glad to give you a fair market value tax-deductible receipt for it.

Two More Servers Donated!

Ben Chobot donated two spiffy new servers to MusicBrainz last week! We received 2 dual quad core Xeon 2.33 Ghz servers with 8Gb Ram and 1TB of storage a piece — these servers will go towards handling our ever growing search traffic. Thanks for your generous support, Ben!

Failed drive in database server RAID array (updated)

Yesterday afternoon a drive failed out of our RAID array in the master database server. We have four drives in this server, with two sets of two drives (using a RAID-1,0 configuration) so a single drive failure isn’t a big deal. We’re still up and running, but we’re quite a bit more vulnerable until we … Continue reading “Failed drive in database server RAID array (updated)”

Yesterday afternoon a drive failed out of our RAID array in the master database server. We have four drives in this server, with two sets of two drives (using a RAID-1,0 configuration) so a single drive failure isn’t a big deal. We’re still up and running, but we’re quite a bit more vulnerable until we get this drive replaced. If the last drive in our RAID-1 array fails we’d have to deal with data loss for today — fortunately the data dumps ran last night and backed us up until then. Let’s keep our fingers crossed that we do not have any failures today.

Once I got notified that the drive failed, I promptly called Sun for a warranty replacement. In the back of my mind I thought: “I should order a new drive from NewEgg, just in case”. But, the Sun representative assured my that they would have a replacement drive for me today. This morning a clueless service engineer called me to tell me that they shipped the wrong drive to our data center. When I called back, they informed me that they did not have the correct drive and that the vendor would ship one to me by Thursday morning.

Having lost faith in Sun to do the right thing, I ordered a spare drive for the server from NewEgg — I should’ve done this a couple of months ago when the prices for these drives become reasonable. Now we’ll have a spare on hand for the next time this happens (and it will quite soon, I’m sure — both Seagate drives that originally came with the server failed within one year. The first drive failed within the first month!)

So, I am curious to see who will win: Sun who had an 18 hour head start to replace the drive, or NewEgg/UPS who got my order just this morning. I’ll post an update once this plays out — in the meantime keep your fingers crossed for no further drive failures!

UPDATE: DHL delivered the Sun drives 1 hour before UPS delivered the NewEgg drives. The drive is now in the server and the RAID array is working optimally again.
