Using a pair of matched WD40EFRX 4TB drives in RAID 1. Life is fine until someone (my son) thumped or dropped the drive. Drive 1 fails first system test. Take EX2 offline, replace drive.
Insert new drive, reboot, no configured RAID volumes. That is odd but perhaps I can create one (not going to commit to that until I know what is going on but I can see what options are offered).
Storage | RAID | Setup RAID Mode button fails to do anything. Look at jquery error codes and it appears that the share list (requested via XMLHttpRequest within the dashboard page) is not found (404 error). Same thing (missing script responses) for Disk Status, too.
Utilities | System Test runs clean but there are no RAID volumes or shares. Factory reset to start over with setting up the RAID…same problem after hard reset.
Firmware: 2.11.142
Any suggestions so I can see the data on the remaining drive and get EX 2 to mirror it again?
