Adding a volume failed
I am reaching 80% of storage use on my 2 volumes (2T each) NAS. So I decided to add another disk. I bough the same type (seagate baracuda) but 3T. When I add the disk I receive this message: The ...
OK, don't hold the power button down as that will force the NAS to shut down. Momentarily press the power button and then release it.
It sounds as if the system did not like your drive, most likely because it was "too small". This happens sometimes, even with drives of the same make and model. Case in point, I have 8 Seagate ST31000528AS 1TB drives that were originally in two NVX units. Roughly a year ago, I replaced two of the 1TB drives in each unit last summer with 3TB drives. Several months ago, I had one of the remaining 1TB drives fail and it took me three tries to find one of the spare drives that the unit would accept. Even if the drive you are attempting to add is only one sector smaller than the previous smallest drive for the drive to be rejected.
The best solution is to back up your data (or if you have a backup, make sure it is updated so you have a current and complete backup) and then perform a factory default with all three drives present. Once it is fully synchronized and stable, restore your data from the backup. Raid behaves this way because it synchronizes the drives sector by sector (even if the sectors have no data) and if the new drive does not have enough sectors, it cannot perform the synchronization.
