ReadyNAS Duo v1 stuck in a boot loop....
My ReadyNAS Duo seems to have some kind of problem. Running 4.1.12. Shares a UPS with my NV+ v2, which is running just fine.
It has got itself stuck into some kind of boot loop. It tries to start, and I hear the disks firing up as the power comes in. As they come up to speed, there is a sound like a semi-metallic click, and the unit seems to go back to the start of the power up sequence again. Each cycle takes perhaps 5s.
The unit cannot be gracefully powered off, even by holding the power button down for a long time. If you take the power out to force it to stop, then attempt a restart, it still refuses to play ball. Naturally the device never gets far enough to appear in RAIDar, let alone FrontView.
Now this has happened before (about two weeks ago), and I did resolve it as follows:
- Tried a OS reinstall. The unit got a little further on the attempted restart but after about 30s went back into its restart loop
- Took out one of the drives (I was expecting I would have to go to a factory reset, and intended to recover the data separately)
- Tried again to do an OS reinstall - this time it worked, and I was able to get the machine working. Checked the logs and found there were no reported hardware or other problems though it was identifying that something had gone wrong (can't recall quite what, and at the moment I can't get at the logs for the obvious reasons)
- Once up, I reinstalled the second drive, and it re-formatted that and put it back into the RAID over 3-4 hours
Worked flawlessly for the next fortnight, until I came in this evening and found it up to its boot loop trick.
Not keen on going through the same palaver every two weeks, so looking to get to the bottom of this and resolve it good.
Both disks have been checked and came out without any problems.
The good news is I have a full backup.
Any ideas?
Richard

- I have this evening managed to restart the device. I did that (as before) by removing the right hand drive in the chassis and rebooting with an OS reinstall.
Two things. First I got the logs off the machine. The file was about 1.5Mb in zipped form. All I could find in it that looked in any way odd were two files httpd_access and httpd_errors which were respectively 2.5Mb and 3.5Mb (unzipped). The backup job logs were about 12Mb (unzipped).
Having got the machine back up, I put the other drive back in the chassis, expecting it to start up, format and go into mirror. However it hasn't. I can hear the drive start to spin up, then after a second or so it makes a squeak. The drive stops spinning up, waits 4 sec then tries again. This sounds like a dead drive, to me?
The odd thing is that I've checked the disk SMART test log and it comes out fine.
One other thing, in case it gives a clue - I noticed that the power supply was running very hot. Any particular likely cause of that?
Richard - I guess if the supply is failing that it might not be able to power the unit with two disks in place. Is supply hot with only one disk installed?
- Hi Stephen,
Yes, the power supply is still pretty warm only running just the one disk. Mean something?
Richard - I haven't touched mine in quite some time, so I am not sure how warm it usually gets. However, if the supply can't provide enough power, then disk spin-up can fail.
EDIT- I just checked it - the supply is slightly warm to the touch, but is certainly not hot. - OK - I'll try and get hold of a replacement PSU and see what that does.
Thanks,
Richard - A new PSU seems to have done the trick. Both disks now spin up without any trouble. The (new) PSU itself is still quite warm to the touch, but not as extreme as the old one. So it looks as though that must have been the problem.
Stephen, thanks for your help, again. Saved me a lot of fruitless problem-solving - my next plan would have been to buy a couple of new disks, assuming these ones were in trouble.
Fingers crossed, of course, that the problem doesn't occur again in 2 weeks time (the old one was having a problem about every two weeks).
