2 dead disks in RNDP6000v2
Hi,
I had disk 3 (out of 6) with bad sectors reccomending replacement so I hot plug replaced it but the NAS did not see new disk insert. I left it overnight thinking it may be formatting or something in the background but then I had another disk fail (disk6). So now I can not access data. Should I restart device to try pickup 1st new drive? But then it may not be able to rebuild volume from remaining 4 disks.
Maybe I need to clone disk 6 ? any help would be appreciated.
It's a ReadyNAS Pro6000v2 with 6 1TB drives using Xraid2, firmware is Radiator 4.2.30.
Cloning disk 6 or the original disk 3 might help get you through this. Note that this usually results in some filesystem corruption (because the unreadable sectors can't be cloned and can't be recovered either). So there could be some data loss. You need a cloning tool that does block by block copying. You'd power down the NAS, do the clone, and insert the cloned disk with the NAS powered down.
If disk 3 is still readable, you could also try powering down the NAS, reinserting the original disk 3, and then powering up again.
Either way, I suggest using the boot menu option to skip the file system/volume check. If your files are available, then do a full backup of the data files on the NAS.
Netgear also offers a data recovery service that you might consider: https://kb.netgear.com/69/ReadyNAS-Data-Recovery-Diagnostics-Scope-of-Service

Thanks StephenB,
I powered down and put origional disks in and booted skiping system check as you said and am now accessing the data and copying to another device. I will then replace disk 3 and reboot to rebuild raid and then do same with disk 6.
Thanks so much you saved me so much time and preciouse data.

Great!

Maybe start with disk 6 this time. Disk 3 will likely lead to the same result (loss of the volume), but it's possible that starting with disk 6 will get you through this w/o losing the data on the NAS.
If the array does fail, you'll need to do a factory default, reconfigure the NAS, and restore all the data from your backup.
RAID redundancy is great, but unfortunately it's not enough to protect your data from loss. Backups to a different device are the best way to do that.
