Were the 4x2TB disks in the NAS when you last did a factory default (wipes all data, settings, everything)?
&nbsp;
There is an 8TB expansion limit over the life of the volume.Do you have a backup?Also note that 4.2.21 was released some years ago now. 4.2.28 is the latest firmware for your NAS.

Hi Mdgm,&nbsp;Thanks for your reply.Our RN 3100 came with 8TB raw disk space and we never did any changes on the configuration.&nbsp;Our plan is take full data backup before performing any changes.So how i can bring this device working with 16TB raw data (4 x 4TB HDDs) instead of 8TB raw data (4 x 2TB)I am bit confused about the 8TB expansion limit over the life of the volume in your reply. Could you please explain the same.&nbsp;Also i would like to know how i can upgrade the firmware&nbsp;BR,Muhammed QTRDoha-QATAR

There is a check-for-updates button in the admin web ui. &nbsp;click on "system" on the left menu, then "update".

If you did the initial install of the system with 2 x 2TB disks inserted, your starting volume size would have been 2 TB. &nbsp;The maximum volume size would have been 10 TB. &nbsp;Since that is less than 12 TB, &nbsp;your system would stop expanding when you inserted the 3rd drive (so the fourth expansion attempt would fail). &nbsp;A factory reset would be needed to fix this.

For the RN3100&nbsp;you should look at enterpise level disks. Perhaps a WD RED Pro 4TB&nbsp;WD4001FFSX or a SeaGate NAS Enterprise&nbsp;ST4000VN0001.Note there are implications for choosing a disk outside the compatibility list, but if you do choose one outside it it is important to make a sensible choice. For rackmount that means going with an enterprise disk.

&nbsp;
I think the seagate enterprise model would actually be the ST4000NM0124, and not the VN.  The VN is positioned against the WD Reds, not the RED Pros.
