Odd LED Pattern on ReadyNAS X6

I can't use the power button to do anything. So we flip the switch to turn it off. When it comes back on, I'm sitting here with RAIDar refreshing as much as possible. While booting, RAIDar shows "disk check" for a split second. Then it goes to "booting" until the NAS stops responding and the LEDs do that thing again.

How long did you disconnect the power for? Could you try leaving it disconnected for 5-10 minutes?

So it looks like it's hanging on booting somewhere. Have you powered down the ReadyNAS, removed the disks (label order) and connected the disks up to a SATA port on your PC and checked them using vendor tools?

If you attempt to boot the NAS without disks does it show in RAIDar with the error message "No Disks detected" in the Info (far right) column?

Do you happen to remember what version of RAIDiator is on this unit?

at one point, it was powered off for about 30 minutes. Still had the same problem.

With all the drives removed, it did show "no disks".

We were able to take the disks all out and do a "factory reset" with a new drive. It worked great. But putting my old disks back in again took us back to the same odd problem. I'll try running the verification tool now.

Sounds like probably a bad disk then. When you put in the new drive, and did a factory reset did you happen to notice what version of RAIDiator is on the unit (I wouldn't suggest updating it for now, but it would be nice to know what version it's running)?

It was running the latest 4.1.8.

Shouldn't the volume be fine until 2 drives had problems?

Normally. Disks can and do fail at any time and sometimes this can cause problems. Typically identifying which disk is bad and removing that disk will resolve the problem.

What model disks are they and how long have they been in the NAS?

Just done with 3 drives. SMART looks fine on each. Quick Test passed on each.
The fourth says "status code=7 (Failed read test element), Failure Checkpoint = 97 (unknown test)" and says "SMART self-test did not complete". But the SMART readout looks fine.

They are Western Digital Caviar Green GT 1.0TB drives. (WD10EACS-00ZJB0) They've been in for maybe 3 or 4 years. Most of that time probably in low-power standby since we only use them occasionally to watch movies.

Fourth disk probably the culprit. Might be passing the short SMART test on boot but then fails to respond during the boot process, hanging the system.

Try running the extended test, particularly on the fourth (but I would also recommend it on the others).

Assuming disks 1-3 are fine, booting the X6 with just those disks installed should work fine.



Most disks tend to have 3-5 year warranties. Some will run for years and years and years, others won't. Disks can and do fail at any time and in a variety of ways. SMART isn't perfect and won't always pick up a disk failure.

Booted fine with 3 disks, our data was cool. We put a clean 4th disk in, and it didn't work. Is one slot special? We turned it off, moved the disks around, and it says "rebuilding" now. I guess we'll see what happens in another 4 hours.
