readynas nv+ green disk LED no longer lights up
One of the green disk LED no longer lights up on a readynas NV+. What are my options? Disk is fine and present in that slot.

- Usually this is an indication of a disk failure, if the disk appears and shows healthy then I would want to check that with more than just those two indicators.
Do you have RAIDar on a machine that is local to the NAS?
If you do, make sure to check the indicators in RAIDar.
I would also go to Status > Logs > Download All Logs (in the upper right hand corner). Once downloaded you can extract them and look at the Disk_smart logs, there should be a bunch of them that have dates (depending on how long the NAS has been online) and then one that just reads "disk_smart.log". The last mentioned would be the one I would want to check for any reallocated sectors or ATA errors. Please post back what you find.
If you are not sure how to interpret the logs, you can send them to me or post them here for further analysis. - I logged into the frontview site and took a look at the disks - all are in good shape. I also clicked on SMART and took a look at the various metrics present. None seemed out of order. My assumption is that the SMART screen for the disk would show errors if there were issues - currently it says OK. I cannot run RAIDar at present since I am not at home - however, I do have shell access and I just took a look at the following log:
/var/log/frontview/disk_smart_2012_03_18.log
=== START OF READ SMART DATA SECTION ===
SMART overall-health self-assessment test result: PASSED
That is the message for:
***** Disk SMART log for channel X [hdc] *****
where X is 1 through 4.
Where else should I be looking? - The Seagate ST2000DL003-9VT166 seem unreliable. The drive in question has 359 hours. The LED went off. I pulled out the drive. Hot event detected. Inserted the drive back in. RAID resync started and the light is now flashing. So, it is not an LED issue but rather a drive issue as pointed out earlier. Why was an alert not provided? Which log should I be looking at to find out what happened? Why is it now doing a resync and not complaining about a bad drive? Why has it not complained about the drive at all ever?
- What's the disk_smart log like for that drive? Please post the full log for that drive (omitting the drive serial number). The 2012_03_18 one should be fine (or the last one before you removed and readded the drive)
The NAS runs short SMART tests daily and on boot. SMART won't always detect a problem disk. Testing the drive using SeaTools running both the short and long tests would be the way to go. ***** Disk SMART log for channel 1 [hdc] *****

Selective self-test flags (0x0):
After scanning selected spans, do NOT read-scan remainder of disk.
If Selective self-test is pending on power-up, resume after 0 minute delay.- After the sync completed this morning the LED is off again. No SMART errors. I guess I have to get a drive enclosure and test the harddrive... Any other thoughts?
- It is best to test the drive while it is connected directly to the motherboard of a PC. Most of the testing applications will not work fully on a drive connected via an enclosure connected to USB.
Another question that was asked but I have not seen an answer to is what are the indicators like when you open RAIDar? In the column for disks you should have 4 indicators and the ones for each installed drive should be green. - Ouch - I don't own a regular PC with a motherboard. Only Windows laptops and a Macbook Air.
All four are green on RAIDar and the first is off on the NAS itself. There must be some log somewhere which says something about the LED being off on the NAS display if indeed it is intentional and not a faulty LED. - In the logs what does it indicate for that disk in enclosure.log?
Sounds like a faulty LED.
When did you purchase this NV+? Was it purchased brand new on/after Aug 21, 2007? - The NAS was purchased used about two months ago to join another that I had bought new several years ago. No labels present so I cannot tell you any sort of date. What is important about Aug 21, 2007?
