Readynas 214 Factor Reset issue
Ok so last night I performed a factory reset on my Readynas 214. It warned me that I would lose all data and that I needed to backup everything. So after tI performed the reset, I noticed that t...

1. What is it resyncing?
A factory default formats the disks, and does a completely clean installation. That includes recreating and syncing the RAID volume.
Note the resync process is needed (and takes the same amount of time) even when the file system is empty.

Yes, but performance will be slower than usual, and the resync will take longer if you are loading data while it is running.
So if you want the fastest path to getting fully on line, you should probably wait for the resync to complete. If you want to get critical data back on line ASAP, then you can of course reload that data.

Likely your disks are of unequal size. In that situation, there are multiple resyncs required to build the volume (one for each RAID group). You'll see the volume go back to it's original size when the last resync happens.

Thank you StephenB!
One more issue with answer 3.

My drives are all the same model and size.
Model WDC WD100EMAZ-00WJTA0
Size 10TB
i really believe the size was in the 30tb area. Will resyncing still help this?

Then the volume was never reported as 37 TB. The capacity rule for single redundancy XRAID is "sum the disk and subtract the largest" - which yields 30 TB. But the NAS reports size in TiB (1024*1024*1024*1024 bytes) not TB (1000*1000*1000*1000 bytes). 30 TB is ~27.28 TiB. So the reported size is correct.

Unless, of course, you were using JBOD, so had no redundancy. That would give you 36.3TiB. If that's what you had and still want, you'll have to turn off XRAID, destory the volume that is currently syncing, and create a new one. But keep in mind that loss of one drive will kill the whole volume when multiple drives are concatenated without redundancy. If you aren't using RAID, you are better off creating a separate volume on each drive, thus reducing the loss to only what's on the one drive.
