Resync after power failure
I lost power to my ReadyNas NV due to Hurricane Sandy but repowered it when the power came back on. RAIDer version 4.1.10 is reporting that Resync is 8% complete and it will take 4 hours and 20 minut...
I am happy to report success in accessing my RAID volume.
I took vandermerwe advice, powered the (4) disk NAS down and removed one of the faulty disk. I then powered up the NAS with three disks inside, let it file check and resync, after that point I was able to access my data volume. The NAS is without redundancy at this point. I again power down the NAS and put back the disk I previously removed. I powered up the NAS again this time with all four disk inside. After file check and resync, I was able to access my data volume again. This time the NAS is with redundancy.
I did some research and found that having ATA errors is not detrimental by itself. What is more important is the rate of getting ATA errors. The higher the rate the more it indicates a harddrive dying.
It seems my original problem was that my NAS could not deal resyncing with all (4) disk present. It had to be gradually stepped up from bare minimum (3) to (4) disks with power cycles in between.
This lesson has motivated me to purchase a separate external USB drive to backup the NAS locally in addition to ReadyNas vault remotely. Another thing I will do is to connect a USB cable between the UPS and the ReadyNas. This way NAS shuts down properly in event of a long power outage.
I thank vandermerwe and all others that have replied to my post. Your advice has alleviated my fear of data loss. Thanks to all again.
