Data Volume Lost after Disk Replace #25483643
Hello ReadyNAS Community,
after a disk failure (disk 3), I replaced this disk. A volume resynchronization was started automatically. However, this resynchronisation failed with no obvious error...
I don't suppose you have a backup of the data on the volume?

Hi,
well no. It's quite a lot of data, was around 5 TB (I had 4 x 2 TB drives), so not actually a lot of space to back it up twice. The NAS was supposed to be the "redundant" backup ;)
So I'm open to any suggestions.
Sending logs is described here, you just download them from the nas then email them in:

There are many scenarios that a redundant volume does not offer protection against, therefore backups are essential.
What model readynas is it?
I think you need to ask Netgear support to look to look at this, open a support case and be prepared to pay.

Thanks for this. I have sent the logs. I have already contacted Netgear, but as you probably know / assume they are not very eager to help. At the moment they are looking into the case. However, I assume that the Netgear implementation of RAID is based on existing technolgoies, and that there is maybe at least one or two rebuild or salvage commands I can try. I was hoping I could maybe find an answer here.
The model is RNS-104, was bought diskless, and has 4 drives in it.
Thanks in advance for your time,
Alex
