ReadyNasUltra 4 dead #26795494
One of the disk was showing increasing Smart errors, so I ordered a replacement disk (ST3000VN000) -to replace the failing disk. No big deal I thought.
I had assumed that the failing disk was d...
Netgear support managed to rebuild the array remotely, using mdadm and then mount the array.
Powered off, removed the bad disk 1 and rebooted with only disk 2,3 and 4 and then could access with fontview.
Put the new disk in disk1 slot, and the raid array has re-synched and we're now back online, all data intact (AFAIK).
Now looking at implementing crashplan on the Ultra4 - though not sure how long it would take to upload data!
Not all the data is backed up - that's the issue - so I'm not really happy with losing the data.
I've created a support case 26795494, and uploaded the logs - though if anyone else has any ideas I'm happy to hear them.
It's pretty difficult to find out how much this service costs - only by searching the forums, and then it's "about"
Hello garethjjones,
The per incident contract is GBP60 good for 1hr but this will possibly fall under data recovery service. Let's see what support center can offer.

Thanks - that's not to bad...doesn't seem like data recovery to me ;-)

Per-incident support does not include data recovery. However, they might be able to successfully mount your raid array, and they might be able to give you some assessment on your prospects of a successful data recovery.
Looking at the logs it looks like a data recovery situation to me. If your data is important then you need to backup your data. In rare cases or e.g. if alerts about disk errors are ignored for too long you can get data loss.
One disk had a lot of command timeouts and another a lot of uncorrectable errors. Two disks have dropped out of the array.
The NAS seems to think that there are five disks in some arrays (though they are still considered 4 disk arrays). In one of the layers one disk is marked as failed and two as spare (though it is a 4 disk layer).
If you purchase per incident support contract and that does not resolve it you may need to purchase a data recovery contract in addition to what you will have already purchased. The support may be unsuccessful.
