Remove inactive volume to use the disk - error msg rcvd after replacing bad disk with a new disk
I replaced bad disk in slot 2 with a new one. Booted up RN214-4. Error msg says to delete inactive volume on disk 2 to use it. Did that, twice. System still shows same inactive volume error. And system reports that the volume on disk 1 is degraded. The data on disk 1 is still there and accessible.
Then normally you need to select the disk on the volume page, and then click on format again. The NAS won't automatically add a formatted disk to the array.
Though another option (IMO better) is to connect the disk to a Windows PC (USB or SATA) and test it with vendor tools (Seatools for Seagate; Lifeguard for Western Digital). If the non-destructive long test passes, then run the destructive write-zeros test. That will unformat the drive, and also gives some confidence that the disk is in good shape.

I used ReadyNAS' format option several times but the error msg to remove the inactive volume reappears each time on the very disk ReadyNAS reportedly formatted (guess I can't be sure ReadyNAS is actually formatting the disk). I will try the PC/Windows suggestion to check the drive out.

Ran the Lifeguard long test, drive passed 100%. Then ran the 0's write, drive repeatedly reported write fail errors. Canceled the write-zero's test and ran the quick format option to write 0's to the first and last 1 million bytes on the drive. Drive then reported being 100% healthy. Installed drive back in the ReadyNAS and, voila! System drives are now syncing for the first time in the X-RAID.
Then ran the 0's write, drive repeatedly reported write fail errors.
That's a bit concerning, so I suggest keeping an eye on this drive. The NAS thresholds for alerting on disk errors are (in my opinion) much to high, so download the logs after the sync competes and check the smart data in disk_info.log. Or if you have ssh enabled, you can check them with smartctl.
Perhaps monitor them after that every week or so for a while.
