X-Raid expands to only 1,6TB when changing 1TB disks to 4TB disks ReadyNAS Duo
I hot swapped the two 1TB disk with two 4TB ones - ona at a time - waiting hours (1-2 days) for each disk to be ready.
The ReadyNAS
Model:
ReadyNAS Duo [X-RAID]
Volume C:
Online, X-RAID, 2 disks, 45% of 1662 GB used
I did read some old discussion on the matter.
They made me reboot the NAS using the "check and fix qoutas" option.
This worked to the extend that volume was expanded from ca 927GB to the current 1662GB.
Not what I would expect as the drives are 4TB.
Trying the same trick more times did not ad to the volume.
Yes I do have a backup of the data. And of the config. But I really would prefer not to factory reset; this should not be nessecary using X-Raid and I would be needing an up-to-date instruction as how to.

Thank you!
I still wonder why it is only 1,6TB and not even close to 2TB
The compatability list is convincing 🙂 (I actually did look at it before but was under the false impression *noob* that my NAS was a v2 ...)
And your first link opens to a solution
buy a new NAS
buy two 2TB drives for the old NAS and run them without redundancy totalling 4TB (or close to?) and use it for backup
It might wise for me to be looking for advice on 1: choosing the right NAS, 2: replacing the old NAS with the new one, and 3: setting up the old one as (on site) backup for the new NAS (should I use my 4TB eksternal backup disk as second backup for the new NAS or as backup for the backup NAS).
I suspect that the 2TB drives for the old NAS does not have to be top grade.

Point 3 could not be an explanation in this case (as the drives are 4TB). Point 2 and 4 might be. Although it seems to be a lot of overhead. But - ok - it is of minor concern now that I am in the market for at new NAS and a new setup.

Don't count your 4TB drives. The NAS only uses 2TB partitions on these drives. So RAID1 out of two partitions of 2TB, minus the few GB of system and swap, minus the difference between TB and TiB, minus filesystem overhead, minus that the NAS round the value (or maybe even truncate it) when displaying it, and you get 1.somethingTB instead of 2TB.
