Mirrored RAID Rebuild at "0.0%"...

All right. Console is up. What am I looking for?

It's risen to 22 percent and has been slowly growing. I'm considering the matter closed for now. I'll just wait the week.

The only one I can see that may or may not pertain to this is:

ENGroupID initWithDataRepresentation - wrong data size -- Failed {data: null}}

But I have no idea if this has anything to do with my problem.

I don't see anything that would be it. Others are Unknown Display and the rest are basically Failed Entitlement Check errors which I know has nothing to do with it.

Meanwhile, it's still sitting at "0.7%" and it's been nearly 24 hours.

Yes. Drive has been formatted the same as the one it’s mirroring. Tried again last night but it’s only at 0.7% after nearly 12 hours.

I've probably got about 100+ lines with that word but I'm not sure if any of these pertain to the drive in question. What exactly am I looking for?

Any other ideas? I am still sitting at "Rebuilding 0.7%".

It's moved up to "11.4%". I am guessing I should just let it run its course. I'm estimating it's going to take a week to rebuild the whole 1.6 TB's.

Thoughts?
