Readynas NV+ V2 Upgrade from 3 X 4TB to 4 X 4TB drives not working
I have been running 3 4TB drives in my NAS for around 3 years. I added a fourth 4TB drive yesterday and after syncing for about 21 hours I have gained no expansion. With the 3 drive configuration I h...
Hello Dooger,
Your NAS is running on a EXT4 file system, the only to fix this would be to seek assistance from the engineers and/or higher tier who can remote in to the NAS and fix this from the backend.
Unfortunately, It shows on your records that the support warranty of your product is already expired. You may try contacting support center and avail a support contract. That should allow you to extend the support for your product so they can escalate your issue to L3 or patiently wait for anyone in the community who has the knowledge in the SSH commands and fixing some issues from the backend. Another option is if you have a back up of the data save on the NAS you may factory default the NAS and reconfigure it from scratch then transfer back the data.

Yes, my first configuration was 3 X 3TB standard desktop drives. These original drives were having to resync every so often do to errors so I upgraded to the 3 X 4TB NAS drives. I removed all the drives and started fresh with the new drives.

Ok. Then you aren't running into the volume expansion limits.
I am a bit puzzled because the resync message is for disk 3, and says nothing about disk 4.
Did you see any log entries about disk 4 being inserted? Also, download the log zip file. There should be a file in there for expansion (not sure of the name for OS 5 though, since I don't own that particular NAS model).
By the way thanks a lot for your help.
Disk 3 was the empty drive bay so that was where the new disk was added. I have downloaded the Log file and went through it looking for maybe something obvious that I might make sense of. I will add the log file from the time the expansion started.
The only thing I found was this:

Based on the logs it does appear that the NAS was already encountering file system error even before the you change the hard drives with larger capacity. The new hard drives did try to sync but encounter a problem in the process that led to this current behavior of the NAS. There are several similar case turn out using the file system your NAS is running. Do you have a backup of the data save on your NAS?
