NV+ appears hung on disk swap
Hi - my readyNAS drives have started reporting sector errors so I decided to replace the drives. I'm installing 4 new WD10EFRXSP drives I started with drive 2 got all the proper alerts - failed d...

Considering that I don't have a second backup of the data on there, what would be the best choice moving forward?
I think you are actually saying that the NAS holds the only copy of the data? Then if you had multiple disks with issues, it was very risky to replace them one by one. It would have been much better to create a backup first.
If the volume is still available, I suggest backing up whatever you can (most critical files first). You might also download the log zip file from the admin ui, and see if there are any disk errors during the resync.
If the volume isn't available, then you could power down the NAS, remove the new disk 2, and boot it again with slot 2 empty. Then back up the data.
Once you have all the data, you can do a factory install with the new disks in place, rebuild the NAS, and restore data from backup.
An alternative is to power down the NAS, and clone drives 1,3,4 to the new drives, using cloning software that does sector by sector cloning. Then power up the NAS with just those disks in place. You can then hot-insert the new disk 2 - which will then resync. One disadvantage of the alternative is that there is likely to be some file system damage on the NAS when you are done. The factory install above would eliminate that possibility.
Thanks - I can see it on the network but can't connect to any shares.
I tried powering down via the power button but it's not responding. Is it safe to just flip the power switch in the back? - just went back to check on it and noticed it did power down on its own. I'm following the rest of your directions and will report back if I get stuck
Ok, just restarted without Drive 2 and got the following email.
Seems like I should have started with drive 4. Should I put my old drive 2 in and pull drive 4 out or does it not work like that?

Disk 4 did not pass SMART self-assessment test. Please replace this disk as soon as possible.
Growing SMART errors indicate a disk that may fail soon. If the errors continue to increase, you should be prepared to replace the disk.All those errors on Drive 4 were likely what was hanging the re-sync. if your shares are currently accessible, make a backup now. Drive 4 is about to die on you. Do Not try inserting another new drive to re-sync, that puts a lot mnore stress on your failing Drive 4 and may push it over the edge. You are luicky if that did not already happen.
yeah - and now the errors are now over 1k. I've pulled most of the contents off the NAS and have a few things left that I'm trying to recover before it's dead.
Once that's done, I'm gong to do a rebuild with new disks.
