Hi Madalin, Firstly, please don't send personal emails - send them to the raid mailing list - you'll get more info that way.

Provided you haven't made any cack-handed attempts to recover the array, I think your chances of recovery are very good. Read before not after? Have you read the linux raid wiki? Is that where you got my address from? Take a good look at it. https://raid.wiki.kernel.org/index.php/Linux_Raid > > Long one is like that: I have a netgear readynas based on BTRFS.

Once raid encounters a fatal error, it marks the array as bad, and refuses to do anything with it, precisely in order to protect your data. That's why the array is dead when you reboot... > I read a lot of stuff since June but nothing based on a moron experience > like mine.

I don't know NASes, but this sounds like you can get to a linux command line? On the raid wiki, go to the section "When things go wrogn", especially the bit where you get the event count from the drives. They should all be almost the same.

You should be able to fix everything with a simple "force assembly" command, but as I say, I don't know NASes. Over to the list. Does anybody know this NAS and can help? Cheers, Wol
