I've been using a Readynas Duo v2 for years now, one disk failed recently and I removed it, now only my 2nd disk is in and I wanted to do a backup before upgrading disks to 2To (current ones are 1.5To), but the device can't boot anymore.
When trying to boot normally, after a few seconds every LED blinks, RAIDar indicates "corrupted root". When trying to access boot menu, the power LED keeps blinking forever, fan turns max speed for hours (even days, I stopped after 24+ hours first time), no way to turn it off except removing power supply.
Any idea of what's happening here ?
I could get an image of the disk with dd_rescue before all this, but it has no partition table, any idea of how to make the disk work again with the NAS ? And if not, how to get data back ?
