TS 439 Pro II unresponsive – forced shutdown only option

[nohill]

Hi there,

I own and use a Qnap TS 439 Pro II for about two years now and up to now had no special issues with it. But that changed recently:

First, one disk was taken down leaving my RAID 5 compromised. I checked it; obviously it had no issues, put it back into the RAID volume and everything's fine. That was about three weeks ago.

Last week the system didn't accept any network connections. The display did not come on when pushing the power button. I did try to connect via SSH to no avail. It only reacted to a ping with no losses and reasonable response times. I forced the shut down by pressing the power button until it went off. After turning it back on, the RAID was checked and everything's fine again.

Just an hour ago I had the same thing going; no SSH connect possible, but it reacts to pings. Forced shutdown.

The system is running the current firmware 3.6.1 Build 0302T and did not mail any error messages prior to behaving unresponsive; this time and last time. When disk was taken out, it did mail that it did so.

I'm getting a bad feeling about this. Any hints what might be going wrong?


Thanks for any input,

Jason

How did you check the disk and what disks models do you have?

I took the disk out and checked the smart status outside the Qnap. No errors. Disks are four 2000GB Seagate Barracuda LP 5900.12 32MB 5900 U/min SATA.

BTW … the system is completely unresponsive this morning again.

Just contacted Qnap support via web. Let's see.

I took the disk out and checked the smart status outside the Qnap.

The best thing to do is run the long or extensive test from the manufacturers diagnostic software.

Disks are four 2000GB Seagate Barracuda LP 5900.12 32MB 5900 U/min SATA.

I assume that translates to the model ST2000DL003? If so, the disk is mentioned as not recommended on the Qnap disk compatibility list. This is a long thread about problems with it.

I can't remember seeing the symptom of the unit becoming unresponsive as typical for the above problems though, so you may have another issue in there as well. Let's hope that support can solve it.

My Qnap lists the disks as Seagate ST32000542AS CC34.

My Qnap lists the disks as Seagate ST32000542AS CC34.

Okay, so the previous model instead of the very problematic later 3-platter one. That's probably better, I hope. I'm sorry for not being able to help.

I have the exact same issue with my TS-410 on firmwate 3.6.1. It started happening after I installed that firmware and now I manually have to shut down the NAS by holding down the front Power button every morning. I'm going to see if I can downgrade the firmware to 3.6.0 to see if it hepls.

My HDDs are also in the supported list, WD Caviar Green. Although they are not suited for RAID 5.

My HDDs are also in the supported list, WD Caviar Green. Although they are not suited for RAID 5.

The only mentioning of WD Caviar Green models on the Qnap disk compatibility list is as Not Recommended Hard Drives, irrespective of disk configuration.

WD discourages from the use of Caviar Green "...in RAID environments utilizing Enterprise HBAs and/or expanders and in multi-bay chassis...". In my world a Qnap definately qualifies as a multi-bay chassis and RAID is always in use for hidden system partitions regardless of what disk configuration the administrator selects for the data partitions.

Green == avoid like plague. Pretty much universally. Cool, you have saved $5/yr. wrt power consumption and have lost data worth $$$$ at the same time. Definitely rocks.

Ok, I see that my disks have been moved to not recomended… But this is beside the point. The NAS behavour started immediately after I installed 3.6.1 Build 0302T. Before this, the NAS had no problem waking up. And I would point out that like the OP said, the NAS is completely unresponsive in SSH, Webpages, network Activity except ping, etc. only hardware off button works.

First I would suggest to re-apply the firmware update again.

Once done so, following the reboot, please check if there are any QPKG (especially older stuff) installed, leading to issues like RAMD disk full, and finally to an non-reponsive unit.
