0 of 0mb used, offline
had a disk go bad on my NV+. replaced it with a larger disk.
initially i pulled the wrong drive thinking it was 3 when in reality it was drive 4. I don't think i messed up the order at any time by putting 3 back into the 4 spot, but i may have...
anyway, i boot to 0 used out of 0/mb and the raid is offline. the resync button is grayed out. i have tried to scan volume on reboot, i tried re-installing firmware via usb.
i have taken the new disk out of the equation and just have the original 3 in the unit, in order. they show up in frontview as healthy and they are about as full as i would expect.
what can i do to rebuild the raid? obviously freaking out here!
TIA!

- Just to be clear -
(a) drive 4 died, so you lost redundancy
(b) you then removed drive 3 by mistake, which made the array unusable
When you reinserted drive 3, was the NAS powered up?
When did you remove drive 4? - I did pull a drive hot and reinsert, not sure which one at this point. Read somewhere nv+ may have treated it as new?! If that is the case, that is retarded.
- A drive insertion is always treated as new. With RAID that is the only safe thing to do (unless you have some way to determine that no data was written to the array while the bay was empty).
- Array cannot be built off of two drives, correct? Sorry for pizza replies, at work in a kitchen and we are busy.
- No, you can't rebuild a 4 drive XRAID array from only 2 drives. The data was spread across all 4, and the redundancy blocks only let you recover from one missing drive.
