Issues since 6.4.0 upgrade on RN516

Yes, me too.  Yesterday (10/17/15) I did, via front view, an update to 6.4.0 on my two 516 boxes.  One came back OK, the other just sat there for 10 hrs saying Booting... on the panel.

Of course I had no front view access, but RAIDar saw the box, and reported management off line.  Diag via Raidar showed no problems.  Folder shares could be seen via WIn file explorer, but could not write or read any data off the box.  Could not resart via RAIDar, could not restart via front panel switch, finially (Painfully) I just killed the power to the box.

Powered back up into the boot menu, and enabled the tech support option

Currently working with support, and will report back here when we know more.

One thing of note on the 6.4.0 update, from the release notes:

Deployment Notes / Limitations:

(snipped)

8: When initially upgrading your ReadyNAS to 6.4.0, a quota scan takes place during boot. This may cause the unit to take some time to do a scan, depending on your volume usage. Allow some time when restarting your ReadyNAS for the first time after upgrading.

PS: one other point.  When it sat there stuck in Booting... and I could not get it to respond to restart, the drive lights were all blue and steady.  The fact that there was no drive activity indicated to me that in spite of there being 14TB of stuff on the thing, it was not doing the afore mentioned quota scan. 

if u have backup then do a factory reset
