I was resyncing the volume on a PRO, and was on the 3rd disk (of 6 total) when it froze on "59% complete". We were doing the resync to "realign" the volume to work with the WD 2TB "Black" drives with 4K sectors (fixed in 4.2.13).
Power cycled it, now shows no volumes and logged the following:
The paths for the shares listed below could not be found. Typically, this occurs when the ReadyNAS is unable to access the data volume.
Any remedy for this other than factory reset? 5TB of business data on it, fortunately some of it was backed up via Vault, but will still take forever for restore.
I'm calling partner support line first, but figured I would post something up here as well
