n5200 SMART Errors and RAID problems

[enzo86]

I seem to be having major problems with the n5200 and the following drive:

=== START OF INFORMATION SECTION ===

Serial Number: WD-WCASM0011601
Firmware Version: 01.01B01

SMART keeps kicking off Current_pending_sector errors on 2 or 3 disk. These are brand new disk. If i reboot the box the errors will some times go away:

This seems to be dropping the disk from the raid 5 array which has become a MAJOR pain. I have had the NAS for the past 3 days and the entire time has been spend resyncing the array many times.

This has become a major nightmare to manage!


Also what is up with the MD0 array as I did not build this raid1 array , is this for system usage ?



per above disk /dev/hdb got kicked out, but SMART doesn't show any problems:

Please Help before this little box gets tossed out the window

Hi,

I have 5 WD 1TB GP (model WD10EACS) hd's in my Thecus N5200Pro.

I do not have your serious kind of problem but I do have the problem that the smart status is displayed as Warning while there are no problems when I run WD Diagnostics (green PASS). This is also mentioned about GP drives in the new HD compat. list on Thecus.com. I would like Thecus to fix this issue.

I noticed however from your smartctl print outs that the version they use in the firmware is 5.33 while there is a newer (stable) version 5.36. There's something about a status code for Marvell controllers in that new version. There's also a version 5.37 but that's experimental. Maybe I go and try to run the newer (5.36) version and see if I still get the smart warning.

Good luck on your issue. Hope Thecus support can help you out

Regards,
Roelof.
