lost device

[Quadgnim]

I posted this as part of another thread relating to an alignment error, but assuming its unrelated, I thought I should create a new thread too, sorry for the dupe. Any help is greatly appreciated. The same drive that keeps reporting it has the wrong alignment, also keeps being evicted:​

I thought I had a bad drive as it kept happening. If I reboot it comes back but as soon as I put a load on the pool I lose it again. After replacing it with a brand new drive I'm still getting the same error.

Then I thought maybe it was a bad cable so I replaced the cable, still no improvement.

Is this a HW issue, if so it would have to be the mother board, but I've been using this MB for around a year and this issue only just started.

Any other ideas?

Thanks

Post the output of the command smartctl -a -q noserial /dev/ada3 in CODE with any disk that has dropped when you put load on it. Right now my guess is that SATA port or SATA cable is bad.

 

[Quadgnim]

see below for output. The drive is currently connected as I've recently rebooted. I wasn't sure if you needed it while connected or when it drops. I've already replaced the drive and the cable, so if it's the port, then its on the motherboard itself, so I hope not. On a BSD forum someone was having a similar issue and everyone insisted it was the power, but there was no solid resolution posted. My system is a tripple core AMD with 8 gig ram and 4 x 2 TB drives and 2 NIC's + 1 onboard nic and on board video. One of the two PCI based NIC's is dual ported for a total of 4 nic's. My Power supply is 450w and my PDU is reporting 350 watts. I'm not sure if that's for all systems connected to the PDU in total, or just the NAS, I need to dig out the docs for that one.

A Power supplythat has fluctuating voltages is bad for hard drives, and they are often the first to respond to fluctuating voltage on the +12v rail(which most stuff gets power from).

The SMART data is good. The hard drive is 41C, which is above the recommended 39C or lower, so you should look at cooling the drive better. But that's not likely to be your problem. I say likely because a hot hard drive will have problems. Some hard drives work fine until the mid-50s, others at lower temps. For long life, thanks to a Google White Paper on hard drives, the rule is 39C or lower for maximum lifespan.

You already replaced the SATA cable, so I'd do some data copying to/from the computer with the new cable. If that doesn't work, try a different PSU. If that doesn't work then your problem is probably that SATA port on the motherboard. I tend to think its not a SATA cable since you have zero UDMA CRC errrors for the life of the drive. That's usually the best indicator of a bad sata cable.

thanks for the quick reply. My room is like an oven. I have the panel off the side of the computer with an external fan constantly blowing on it. The plan is to move them to the basement, but my basement is in disrepair due to water damage, but I'm working to get it back in order. It's a good 20+ degrees cooler down there. I appreciate the feedback. I'm thinking maybe I should jump from a 450w to a 650w psu and see how it goes? The weird thing to me is its always the same drive that fails, the 4th one. I don't know if it's maybe how the drives are powered along the chain, or it is in fact a bad port on the MB, but I only have 4 ports, so I can't really test without a new MB. What's the more likely scenario, get a new MB or a new PSU?

The MB that's in there was purchased 12/2012:

Biostar A780L3C AMD 760G/SB710 Motherboard - MicroATX, Socket AM3, AMD 760G/SB710, DDR3 1600 MHz (O.C.), USB 2.0, SATA II (3Gb/s), 6-CH Audio, LAN, PCIe 2.0​

MPN: A780L3C was pretty cheap at $47​

​

The PSU also purchased 12/2012:

the PSU came as a case and PSU bundle for a whopping $40, so it's not a very good PSU​

I wouldn't necessarily go with a higher wattage PSU. You want to be in the 30-80% of your PSU's designed rating. I doubt your system is drawing the full 350w. That has to include other things.

Those types of PSUs that comes with cases should never ever ever be used in a computer. They often burn out and destroy ever component in the computer at the same time. I'd be shutting down your server, unplugging the power supply and getting a new power supply before you ever use it again. Read this article. He does thorough reviews of power supplies, but the article is hilarious and informative. He was serious when he mentioned he kept a fire extinguisher handy when testing a PSU like yours. If you were my friend I'd make you turn in your computer geek card. Those should never be trusted...ever.

I will say that when you buy cheap components(especially for server applications) you get exactly what you pay for. Poor engineering designs and less than stellar components included.

For servers, its all about buying good quality components(and preferably server components for servers).

Hi,
I am having a similar problem with one of my drives. It goes offline every now and then but if I 'zpool online' it will resilver ok and stay up for a while.
Message in the log is same as yours "kernel: (ada1:ahcich1:0:0:0): lost device" and I am also suspecting a PSU overload issue.
Were you able to identify the cause on yours?

 

[Quadgnim]

I did resolve it but not sure which of two things did it.

Prior to new PSU I changed the 4 drives from two separate mirrored pairs to a striped mirror raid 1+0.

For several days afterwards it worked fine then I installed my new PSU once it finally arrived and I've not haf an issue since.

 

[np141592]

Tnx for reply.
I have a 450W PSU for a phenom II x4, regular MB, 8GB, 6x7200 rpm HDD, 2 NICs, no video and few fans. I'll reopen the case to recheck all power connections.
If I'll still have the problem I'll change the PSU with a 600W one I have laying around.

 

[np141592]

Just wanted to follow up on this. I have changed the PSU and all looks good now.
