ReadyNAS 3220 Replacement disk offline
I have a ReadyNAS 3220, fully populated with 2TB disks. Recently, the disk in position 2x2 died. The RAID has been configured as RAID10, and had two hotspares. When the drive failed, the RAID transitioned over to one of the hotspares without issue. I replaced disk in position 2x2 with the exact same manufacturer make/model (Toshiba MG03ACA200- all of the disks are this model). The disk shows up in the Volumes interface, but the green light is not on in the interface. The ReadyNAS recognizes the disk. I have formatted the disk using the ReadyNAS interface. However, the disk does not show up as online, and I cannot add it to the RAID.
How can I get this disk online, and add it to the RAID10 array?

Have you tried connecting that disk up to your PC, deleting the partitions off the disk, putting it back in the ReadyNAS and trying to add it again?
I have not. This ReadyNAS is at a colocation facility, about 50 miles from me. Is there a way I could do this over SSH instead of pulling the disk and doing it on another computer?
OK, so I SSH'd into the NAS. The disk in question is sdb. Running "lshw -class disk" shows the disk, with no mount point and no partitions. Running "fdisk -l" shows the disk, but throws the warning message "Disk /dev/sdb doesn't contain a valid partition table."
So, do I need to create a GPT on it manually?
Have you tried support?
I've not selected an answer because this is still an issue. I have one disk that is offline. I've reseated it. I've reformatted it. I cannot add it back to the RAID10 as a hotspare. I cannot add it to the RAID10 as any sort of member. The ReadyNAS sees the disk, knows the make, model, firmware, location, etc. I'm not sure what to do with it at this point.
Hello thedutchman,
It is best to contact support center for this concern.
