ZFS mirror continually disengages one drive and resilvers it

After months of having a ZFS mirror of two drives work fine, the last week my pool seems to continually disengage one of the two drives (the same one) and shortly afterwards begin resilvering it. The resilver completes. Then in 1 -2 days the same thing seems to happen again. Some of the error log entries I found are below. I looked at SMART report for the drive that keeps getting disengaged and did not see errors in the stored runs of SMART.

Can anyone suggest how to solve this problem? The drive that keeps disengaging is a 6 Tb drive and I don't have that size as a spare, and can't tell if anything is wrong with the drive.

I'd start with a smartctl - x of the failing drive. Your drives are definitely too hot.

Thank you, I'll try it and post the results when I'm back home tomorrow night

A few things real quick...

1) Do you run SMART tests frequently, both short and long test?
2) Have you tried to connect the drive to a different SATA port and use a different SATA cable?
3) Have you looked and tried the Hard Drive Troubleshooting Guide in these forums?
4) You are having problems with the drive on ada0, correct? I ask because looking at the data it only shows one entry where is states is was ad8 but I see nothing more about it.
5) If you don't have your data backed up, well I'd get moving on that first. Safe your data.

EDIT: I agree 100% with those drive temps are TOO HIGH! You are just looking for early drive failures once you start running them over 40C for any length of time. Figure out that cooling issue and fix it unless you want to replace drives frequently.

Thank you both for the suggestions. I looked carefully at the output of smartctl -x on the "failing" drive and didn't see errors or recovered sectors but the # of power cycles was way too high--considerably higher than another identical drive on the system that has been there longer. Both drives were plugged into the same rail on the power supply. So I tried tapping one of the unused rails for the 2nd drive. It has resilvered once now and just stopped. The higher temperatures, were because shortly after a power cycle, FreeNAS would restart the resilvering. So both drives had been running their fastest in a warm closet.

Now I am seeing 44 Celsius temperatures out of HGST Deskstar NAS 6Tb 7200 rpm drives. Does that seem too high? Smartctl -x says:
Min/Max recommended Temperature: 0/60 Celsius
Min/Max Temperature Limit: -40/70 Celsius

Do you think the drives were running too hot at 50 Celsius given they were loaded and are 7200 RPM drives?

Yes. I've got a similar situation I'm working through... I've got 15K SAS drives running 46-49C, and I feel that's too hot. They are probably similar to yours... in a closet at home. I didn't want to go to a full AC system due to cost and freeze-up issues (4x8x8 closet, not enough air space) so I'm doing a push-pull fan arrangement with air filtering. Making progress...

Yes.

You should try to get them down to 40C if possible. Placing a system in a closed closet is a bad idea. If possible maybe you could cut a vent in the top of the closet and run a vent above the closet door so hot air can escape. If the bottom of the closet door doesn't have a .5" gap then maybe you could cut off a small amount to make the gap to allow cool air in the bottom. And if that isn't enough cooling, a few 240mm fans and cheap wallwort could be mounted tot he upper vent to force the hot air out.

Yea, if this is not your house then maybe it is not an option, but it's a possible solution if you have no other location for the hardware.

Thank you both for the feedback. It's not my house and the closet door is always open. I don't want to air condition the place during the day when I'm not home. I will try adding another 120mm fan to the case if it has a place for it. I wish I had bought 5500 rpm WD reds again, those ran a lot cooler

Your problem is not your drive selection, your problem is inadequate cooling. You need to fix your cooling problem or you'll likely be spending a lot of money on drive replacement.

Penny wise, pound foolish.

Thank you everyone for your suggestions. My case already has 2, 120mm fans blowing air out the top and back of the case, and 1 120mm fan blowing into the case and across the hard drives. I will try copper fin heatsinks, which Steve Gibson has said provide a surprising amount of cooling for hard drives. With everything set up the same way in the case, the WD reds definitely ran below 40 Celsius. I guess I have inadequate cooling but it sure wasn't until I went with the HGST 7200 RPM drives.

I still would like to see the output of smartctl -x for the drive.

After all, we have seen many thousands of these from many customers, and have quite a bit of experience teasing out things from the SMART report that may not be discernible to most people.

Here is the output of the smartctl -x for the drive. I didn't know how I could post it before. I redirected it into a file then opened it with Windows Notepad and tried to add line breaks where they should be. If you know a better way please say. I also attached a copy of the same smartctl output in a the file freebsd created, maybe you have an editor that can read it properly. I appreciate whatever you can tell me about how the drive is running from the output.

A couple of observations:
1. As noted above, the drive is running hotter than generally recommended in these forums.
2. Are you really writing 2GB and reading 5GB per hour on that drive, or is my math off?

Thank you for sharing your observations. Regarding #2, most of the time my drives are idle but when they are in use, the figures seem approximately what I'd expect as I often record and stream HD video.

OK, well other than the above, and the one error recorded at 0 lifetime hours, I don't see anything obviously wrong with the disk. However, you don't appear to have regular SMART tests running, so you might want to address that.

Thank you for looking and for the heads up. I intended for the freeNAS to run them monthly, I'll review everything to make sure they run as intended.

Your smart long tests should run 2x a month and then you shoudl setup short tests for every week. This is a rough guideline and lots of people do it different but you want some long tests and a couple more shorts tests.

Hi,

I had exactly the same issue and it was frustrating the h*ll out of me.

First thing, whilst I don't disagree with anything anyone has posted, I'd be surprised if it was inadequate cooling, drives failing or SATA ports or cables.
Even though it's usually a good idea to keep drives at or below 40 C, the HGST drives you mention have an operating maximum of ambient temperature of 60 c - that's the air temp of the room, not the disk. The temp of the disk is going to be higher than that. There is also evidence to suggest that over-cooling kills disks just as much as over-heating.

What I'm interested in knowing is if the problem has resolved since you changed the power supply arrangement?
My issue was I was overloading the 12v rails on my PSU by having 4 disks on one cable - admittedly I had 9 disks and 2 SSDs on 3 cables, but now with no more than 2 drives per cable I've not had a single drive drop out of the pool. It might be the power consumption of 6TB 7200 drives was too much for the single rail, especially especially if you had other devices hanging off it.
The other thing it might be is first signs that your PSU is giving up.

Indeed sir, no one will dispute this.

But I want to be very clear: what we do in this forums is drives. NAS. File storage. HDD arrays. Specifications on drives offer numbers like 60C ambient, 80C operating, and so on. That being said:

All of us in the FreeNAS community can *STRONGLY* advise everyone that regardless of the numbers listed on spec sheets, our users *CERTAINLY* experience vastly degraded longevity if their drives, themselves are operating much out of the 40's. I would never *DREAM* of operating a drive at 40C or above in a 24/7 NAS, and even the most forgiving FreeNAS veteran will certainly not countenance anything above 45C or so.

It is true that there appears to be a (minor) drop off in longevity for drives run in the 20's (i.e., "too cold"), but the effect is very minor, and cannot necessarily be normalized to be purely causal based on the temperatures. On balance, running your drives around 27-37C seems to be absolutely ideal in our experience with small to medium arrays, and I think I speak for everyone when I say that regardless of spec sheets, our experience is that drives running well above 40C generally have many more problems, and less longevity, and that the effect is quite noticeable.

Damn the spec sheet---focus instead on what the collated and collected experience of a hundred thousand FreeNAS users says.

Run your drives in the 30's, at worst. Period.

But, yes.

Check your power supply, and it's cable layout.
