Thanks, but no, I’d never end up doing anything meaningful with it, even if I could dig up appropriate cabling. You’ve both provided good advice in helping me through this process. I’m fairly certain that ZFS is the way to go. Even if you don’t, it isn’t that unusual to find that your storage vendor was decent enough to use drives sourced from two or more batches in building your array, which would appear to be tacit acknowledgment that using all one drive from a single batch is a really bad idea. Consider for example, a commonly quoted authority on the subject, NetApp, who submitted the following a while back.

I’m installing freenas 8. I’d like to end up around 10TB. The Google 3waee showed a REALLY impressive correlation for drives from certain batches failing in groups; you can of course ignore that and you’re probably okay, unless you happen upon one of those bad batches, in which case you are totally screwed. So take advantage of the modern era, make your data safe, use a heterogeneous mix of drives if you want to improve reliability.


Auto-carving divides the available unit capacity into multiple chunks of 2 TB or smaller that can be addressed by the operating systems as separate volumes.

Packaged Quantity for specs. That’s kind of the idea. Running a verify on the array, just in case. It makes it worlds easier to support when no matter what bay the drive that fails comes from, there’s the same number to call for a replacement. I’ll try a firmware update anyway and report back. I can point to numerous discussions of this. This is not the age of SCSI busses where you had incompatible firmware on different drives on the same bus and you’d get lockups if you mixed them.

I’m well known as the primary developer behind Diablo, the Usenet news package used by numerous service providers, who compete with each other on how many petabytes of storage they currently offer. Now the 3ware raid controller card no longer sees any of the drives attached to it.

You might find that going to JBOD or passthru mode “fixes” whatever the problem is, anyways, so it’s worth a shot going that route. It’ll make them double check the compatibility before they answer you.

Ars Tribunus Angusticlavius et Subscriptor. I decided to do a CPU swap this afternoon, replacing a pair of 89 watt Opterons with a pair of 55 watt Opterons.

Discussion threads can be closed at any time at our discretion. I would love to hear that this happened to one of my competitors, but nothing such as this has ever come my way.

Anyone have anythoughts on this? The new 2TB drives we recently ordered are working perfectly, so we’ll send the 3TB drives back. Be respectful, keep it civil and stay on topic. Probably because 3 marketing terabyte minus 2. Post as a guest Name.

Environmental Parameters Min Operating Temperature. I got the “Complete 9. I have been searching, but I cannot find a spec sheet that lists the card’s maximum single drive capacity supported.

Consider for 950, a commonly quoted authority on the subject, NetApp, who submitted the following a while back. Wed Oct 20, 1: Make sure you ask that if the card doesn’t pick up the array, that they cover the cost of data recovery.

For a FreeNAS deployment, the majority of users are free to pick and choose their hardware. I’m guessing will cause some problems later on down the road? Your competitors thank you 3wars.
