I messed up my array and I don't know what to do

[Tired_]

I would leave it off until I had airflow directly over the drives.

I am currently using this: http://www.coolermaster.com/product.php?product_id=2542. With the big fan in there, I thought that would be enough to cool the drives, apparently it isn't. How much airflow does one need?

Also, I appreciate what you are saying (and am very grateful for all your help!), but is there any way we can try to get my array back working and then I'll shut it down until I get better airflow?

No, it means if this was my array I would:

Code:

shutdown -p now

Which powers off the machine. I would leave it off until I had airflow directly over the drives.

If ada1 is OK, which it appears to be from the SMART output, then the array is likely in better shape than it first appeared.


A resilver causes a lot of seeks and nothing generates heat like a lot of seeking.

Agreed, there's no point in getting a resilver started and having it fail part way through. Its better to be patient and get it done right if you want the best chance of getting your data back.

I'm not so sure your motherboard/cpu isn't overheating as well. I wouldn't even try coping the data off until after the cooling is fixed. The array won't get any worse shutdown. It might if you persist.

Also, the array is working, degraded but working. The machine wasn't, probably from heat.

Am I understanding correctly? You won't help me fix my array until I get better airflow? I'm not sure how to address that; I moved the drives around, they don't seem very hot right now, but I suppose they wouldn't, cuz they aren't in use. How can I demonstrate that my temperature problem is resolved, so we can move forward (I really hope I am misunderstanding you...)?

Do you understand I have no reason to help you do shit? What I am strongly suggesting is you fix your overheating problem before continuing. If not you may lose all of your data.

You should be able to auto-import from the GUI and replace ada2, with ada2, from the GUI as well.

PaleoN is correct. You are at the point of most likely getting your data back. If you take ANY risks and something goes wrong, you are where you were before we started helping you and just wasted our time and yours.

I do understand that you aren't required to help me, and I hope you understand that I do appreciate what you have done for me. I'm just a bit taken aback that my system (which up til a couple days ago I thought was doing fine) has apparently been near death for almost it's entire life (it was built in late 2012). Heat problems was something I hadn't considered at all, and I'm trying to wrap my head around it. I checked my CPU and motherboard temperatures in my BIOS, and they are around 60 degrees Celsius for the CPU (which, according to Google, is relatively normal for an idling Pentium 4), and the motherboard sensor says around 42 degrees. I already bought the Cooler Master hard drive fan thingie, the case has fans everywhere they can be put...how else can I reduce heat/increase airflow? Please don't misunderstand, I am not trying to be ungrateful or entitled, I just want to understand the problem I'm having so I can fix it for good.

What if I got a few of these? http://www.newegg.ca/Product/Product.aspx?Item=N82E16835119063

each drive has an empty bay between it and the next drive, if I bought five of these and put them between each drive, do you think that would cool things enough to be safe, or am I looking at this completely the wrong way?

 

[ProtoSD]

Can you post a pic of the inside of your case so we can see how things are layed out? Maybe there's something someone can suggest.

It's too dark here to take a picture, I will post one in the morning.

60C is NOT normal operating temperature for a Pentium 4. That's only 20C from when you should be panicking and doing anything you can to cool the CPU if you want it to continue to function(including shutting down the computer). 40C is generally normal for an idle CPU.

You have heat issues, and like paleoN and protosd said, if you don't spend the money to fix them you can kiss your data goodbye at some point in the near future. Your data looks like its safe. Don't blow your chance and try using the machine until your heat problems are solved. A Google whitepaper recommended hard drives stay below 45C for longevity, above 45C and hard drive lifetime begins to drop.. rapidly. Yours are 58C. In fact, I think that's so hot if they pull your SMART data from the drive for a warranty RMA they may not honor the warranty because you were far outside the operating range for the drives at some point. Yes they can and they have been known to do it.

By the way, you are using 7200RPM hard drives in that 4 drive carrier. I had 3 of those before and their documentation said not to use hard drives that are more than 5400RPM in them to prevent overheating. I can also vouch that if you do attempt to use 7200RPM drives in them, they are virtually guaranteed to overheat. Even trying to use empty bays makes things worse because you get high airflow through the empty bays and the full bays literally have no airflow. That's why when you buy those 24 drive 4U cases with all the bays next to each other they have a little slide to block airflow to empty drive bays. I don't think yours has that option.

You should go back and reconsider your design if you want a long lifespan from those drives. :(

Ok. I took your advice and shut down the server till I could deal with the heat problems. I knew it would take me a long time, which is why I wanted the array undegraded before I took it down. You guys thought that was a bad idea, so I took your advice. I've purchased a proper server case, and got lots of airflow on all the drives. Unfortunately, during the time the server was down, the USB drive that had the FreeNAS on it was destroyed, so I have downloaded FreeNAS-8.3.1-RELEASE-p2-x64 and booted from it. I tried to auto-import the existing array, and (after about 15-20 minutes), I get "There was an error" at the top, and the array doesn't import. zpool status shows one drive as UNAVAIL (I guess that's the one drive that was wiped with SeaTools). I'm lost now, how can I recover my array?
