I/O Error on QNAP TS469U-SP internal drive

Postby benalexau » Thu Sep 12, 2013 9:20 am

Hi

I have a TS469U-SP with 4 x Hitachi Ultrastar 7K4000 drives configured as a single RAID 5 volume. Today the QNAP reported:

[Harddisk 4] I/O error, sense_key=0xb, asc=0x0, ascq=0x0, CDB=88 00 00 00 00 01 ce a0 5c 58 00 00 00 08 00 00

In HDD Smart summary, the QNAP reports, "HDD I/O Status Abnormal". A "quick test" completed without finding any errors. A "full test" is running but incomplete. A copy of the dmesg from an SSH session into the QNAP is below.

Any suggestions?

Thanks
Ben

Re: I/O Error on QNAP TS469U-SP internal drive

Postby QNAP_YH » Fri Sep 13, 2013 6:05 am

Hi,

ata10 of TS469U-SP indicates Bay 4 and/or drive 4.
And I/O error, dev sdd, sector 7761583224, means your drive 4 w/ bad sector.
sda = drive 1, sdb = drive 2....

You have to replace your drive 4, please refer following compatibility list.
http://www.qnap.com/useng/index.php?sn=4085&lang=en-us
Please must refer note behind hard drives before purchasing.

Hi

The disks in the NAS (and the NAS itself) are only 10 months old. They are Hitachi Ultrastars (with 5 year warranties) and appear on the compatibility list. I ran the QNAP "complete test" and it reported, "Status: Test completed and no errors found". There are no new errors in dmesg. So if I return this drive, is this dmesg alone enough to prove there is a problem? I don't want to lose redundancy (it's RAID 5) to return a drive that will be returned to me as no fault found. Is there some other test that can be run which will demonstrate a fault with the drive, as the quick test and complete test have failed to identify any issues?

Thanks
Ben

Hi,

The disks in the NAS (and the NAS itself) are only 10 months old

QNAP does't sell hard drives, if you bought QNAP w/ hard drives inside, it should be bounded by re-seller or distributor.

They are Hitachi Ultrastars (with 5 year warranties) and appear on the compatibility list

I believe it is under compatibility list, however, please give me the hard drive model#, so I can double check for you.

I ran the QNAP "complete test" and it reported, "Status: Test completed and no errors found"
In HDD Smart summary, the QNAP reports, "HDD I/O Status Abnormal"
s there some other test that can be run which will demonstrate a fault with the drive

As you described, SMART has shown "abnormal" on QNAP web interface, however the SMART exam result actually is from the firmware of hard drive,
which is from Hitachi hard drive firmware.
Of course, you can go to Hitachi's website to download their diagnose software, connect drive 4 on your PC and run "detail diagnose".
Using this method, you can get more accurate result than SMART.

Additional information, if you go to [Control Panel], [Storage manager], and physical disks, choose hard drive 4 and run [scan now].
It may show bad block information.

I don't want to lose redundancy (it's RAID 5) to return a drive that will be returned to me as no fault found

If I were you, I will backup my data first, then I will not worried about losing RAID5 redundancy during hard drive replacement window.

As you described, SMART has shown "abnormal" on QNAP web interface, however the SMART exam result actually is from the firmware of hard drive, which is from Hitachi hard drive firmware.


What's puzzling is the smartctl result above does not show any errors either. I would have imagined whatever QNAP's web admin GUI is saying is coming from the drive's SMART feature, but it doesn't seem to be. The only two indications of a problem are the dmesg log posted earlier and the web admin GUI telling me "HDD I/O Status Abnormal". No quick test, full test, smartctl or new dmesg indicates an issue.

Of course, you can go to Hitachi's website to download their diagnose software, connect drive 4 on your PC and run "detail diagnose". Using this method, you can get more accurate result than SMART.


Only problem with that is I don't have Windows, and I don't have a workstation with a 6 GB/sec SATA interface in any event (only 3 GB). I am also reluctant to knowingly eliminate redundancy (by removing the drive from a production QNAP) just to run a test of a drive that doesn't seem to be that critical. Are there any commands or packages I can install on the QNAP to investigate this further? Past experience tells me if I ship this drive back to Hitachi without hard evidence of a problem, they'll just send it back to me with "no fault found" -- especially given I can't find a fault locally with any commands.

If I were you, I will backup my data first, then I will not worried about losing RAID5 redundancy during hard drive replacement window.


I have ongoing backups of important data with ElephantDrive (great interop with the QNAP BTW). I'd hate to see how long it takes to restore many hundreds of gigabytes over an Internet connection though!

Is there anything else I can try on the QNAP itself? Are you sure an I/O error is indeed a drive problem as opposed to a SATA interface issue? I read a few comments elsewhere that suggested I/O errors could be a faulty cable or connector. Does this seem plausible given what we're seeing here with no SMART errors?

Code: Select all

/etc/init.d/klogd.sh | grep ERROR


dmesg only contains logs after start-up, you can find more logs by klogd.sh

Did you also try bad block scan?
Go to [Control Panel], [Storage manager], and physical disks, choose hard drive 4 and run [scan now].

Did you even bother to read the SMART info?

You have 316 bad blocks there and triggered an attempt to reallocate them 427 times. The disk is sure like ** faulty and to be replaced! It absolutely does not matter that they are "only 10 months old". RMA it!

Yes. I followed the first Google result for "smartmon tutorial" and it pointed me to the lines of my output which said, "SMART overall-health self-assessment test result: PASSED". Unfortunately I didn't read the lines you identified.

I really appreciate you interpreting the output for me. Thanks!

I am on firmware 3.8.3 Build 20130426. I have looked through the web admin interface but cannot find a Control Panel. Is it somewhere else? Apologies in advance if I am overlooking something really obvious.

In view of doktornotor's reply I am happy to RMA the drive.

Thanks for your help.

Hi,

Per your klog result,

Code: Select all

<3>[242938.752969] end_request: I/O error, dev sdd, sector 7761583192
<3>[242938.753056] end_request: I/O error, dev sdd, sector 7761583200
<3>[242938.753154] end_request: I/O error, dev sdd, sector 7761583208
<3>[242938.753238] end_request: I/O error, dev sdd, sector 7761583224
<3>[242938.753321] end_request: I/O error, dev sdd, sector 7761583232

There are more I/O errors indicate hard drive 4.

I am on firmware 3.8.3 Build 20130426


For firmware 3.8.3, you can find [Scan Now] under administration -> DiskManager -> volum management.
A reference picture is as following,
