TS-419P II - Disk Read/Write Error

[clickright]

I too am having this issue with the my brand new TS-419 PII and 2x WD RE4 2TB WD2003FYYS drives! I made a post about this here. Basically Drive 2 is going offline when the SMART test runs

Have you upgraded the firmware on your RE4 drives to at least: 04.05G05 ?

I disabled all SMART tests on my unit and now the RE4's have been working for 3 weeks without problems. Still incredibly disappointing that the test process would cause the drive to be dismounted, but so far it's the only way I can get the unit to operate reliably.

Both rapid and complete SMART tests work without problems with other disks (personally I use two different Hitachi models and one Samsung disk). Since SMART is in fact a feature of the disk rather than the host system, this very likely is a WD issue and I'd recommend that you take it up with them. Maybe there's a firmware update fixing your issue?

The document you're referring to is for the RE4 GP (WD2002FYPS), so a different model than in the post you're responding to.

Confirmed. On my unit it is always disk 2, regardless of if I swap the disks (Meaning it's not the drive but the QNAP unit.) Looking on the forms, others have random drive drop out on different bays, seemingly when the SMART test rune. (I only have two disks so I assume that if I had disks in bays 3 and 4, one of them would do the same.) My solution is to replace my QCRAP with something else since it is so new, unfortunately I don't have a solution for you.

I'm not saying that for sure there isn't a problem with the Qnap but with your limited diagnose, I'd say that you're jumping to conclusions.

Most of the problems with incorrectly dropped disks are with incompatible or questionable disks like WD Green or Seagate ST2000DL003, ST3000DM001 and ST2000DM001. Personally I think Qnap may have made a mistake (maybe pressured by Seagate?) when putting the two latter models back on the compatibility list (with an exception only for the TS-XX79 model line). There are far too many reports about problems on other NAS models as well to be normal. Time will tell...

I beleive the issue you see with WD RE4 is something different. My first guess, based on the fact that SMART testing is in fact a feature of the disk rather than the host system and that it works perfectly with other disk models, is that it is a disk issue rather than a Qnap problem. Have you checked what WD has to say about it?

I swapped disks. Disk 1 is where disk 2 was and disk 2 is where disk 1 was. Then I rebuilt the array and ran a Complete SMART test on disk 1 (Which was disk 2 -- the "failing" disk ) it passed the test without causing a read/write error. Then I tested Disk 2 (Which was always the "good" drive) said there was a read/write error in volume management, leaving the array in a degraded state. (The same thing that happened to the other Disk 2) The SMART test completed successfully as always. I am not suspecting an issue with the drives based on this-- I will find out soon!

OK, so my Synology DS412+ Arrived and I installed the both my RE4 hard drives -- They work without a hitch! The QCRAP would give a read/write error on "disk 2" shortly after starting the complete SMART test, the Synology goes right to 100% without a problem.

For anybody else searching the forms, the WD RE4 2TB WD2003FYYS drives do NOT seem to be compatible with the QNAP TS-419P II unit as advertised.

Sharing in case it helps. After much trouble with recurring "disk read/write error" or simply "disk removed" or "system shut down unexpectedly" followed by lengthy rebuilds, I managed to fix the issue in an unexpected way.

Spoke too soon. Random errors appeared again, Qnap support eventually concluded the hard drive backplanet is corrupted and needs replacement. Sending unit back for service under warranty...
