ReadyNAS Pro 6 - Volume scan failed to run properly
Hi -- Long time ReadyNAS user with very few problems to report. Just ran into one, sadly. I have a ReadyNAS Pro Business Edition [X-RAID2] with 6 disks running RAIDiator 4.2.28. FrontView rep...
A follow-up : I did indeed need support, but they were able to restore the volume with 5 good disks out of the six. They had to escalate to level 3 and remote in, but were able to get everything working again. The NAS was well past warranty, but the $75 per-incident support was money well spent.
And for the record, Netgear support was stellar. Every person I spoke to was competent, knowledgeable and polite. They called back when they said they would and didn't miss a beat, regardless of the handoff between four different people (or more, for all I know). Great job, ReadyNAS Support Team!
I never intended on that hot spare. We have XRAID2 and for whatever reason (this never has happened before when one drive failed, was replaced, while another was giving trouble) AFTER the rebuild failed it set the new good drive 5 was set as a hot spare for no frigging reason. The 4 drives were showing all the data in the volume just fine, but it was read only due to life support mode. Why wouldn't it rebuild with 5 I have no idea. We still have the old drive 5, but in theory, we'd only need one new drive to replace the dead drive 6.
There has GOT to be a way to recover this because we DID HAVE RAID 6 YESTERDAY! How can the entire volume be lost with RAID 6 and/or why the hell would it go from RAID 6 to RAID 5 with a hot spare just because drive 6 just died?

You didn't say anything about RAID-6 in your earlier post. You are saying you had set up XRAID2 with dual redundancy? By default it is only single redundancy.
Netgear Support can tell you exactly what raid mode you were in from your logs.

Understood. My explanation (which assumed single redundancy btw) is that the resync failed because drive-6 failed while it was running. So drive 5 was never added to the array. Of course I only have the information in your post to go on.
Again, Netgear support should be able to tell you what happened.
