Title: RAID 5 two disk down, how to recover data
Post by: palantir on July 14, 2016, 12:51:42 PM
Hey Forum,

I have a LS-QVL/R5. For several years it worked fine until a couple of days ago when one of the disks failed. I didn't have any spare disks lying around so I ordered two new ones and swapped out the broken disk. I went through the procedure of rebuilding the array (I had never done this before so I didn't do it 100% correct, but it it seemed to work).

The NAS took a while to rebuild the disk so I just let it do its thing and went to bed. This morning I woke up to find a second disk appeared to have failed. Right now the NAS is showing both disk 3 and 4 to be in 'Error' state and where it previously stated that Array 1 was configured now it says it isn't.

Can I still recover my data and if yes how? What is the procedure?

thanks,
Jurgen

Professional data recovery is probably your own option if you have two physical disk failures.
