Expansion size not adding up..... Any comments!!!
I have Ultra 6 with 4x 2TB (Seagates: ST32000542AS) and just recently added 2x3TB WD (WDC WD30EZRS-00J99B0 )
I was expecting 11TB more or less, but some how the the NAS only see 9TB on Frontview/or CIFS share...... can anyone shool me on the particular of expansion size and volume limitations?

- So you're using X-RAID2 single-redundancy?
Don't forget that the NAS considers 1KB = 1024 Bytes whereas disk manufacturers consider 1KB = 1000 Bytes,
So 11TB of redundant storage is really: 11000 * 1000^3 / 1024^3 = 10244.5GB
Of course there's overheads as well, so the actual volume capacity would be less.
What is the volume status under Volumes > Volume Settings in Frontview?
Have you tried rebooting the NAS? Perhaps vertical expansion has not taken place yet. - Check devices /dev/sde and /dev/sdf which I presume are the 3TB drives, but which are being reported as having capacity ~2TB.
Seems the issue is one of both wrong expectations (should see ~10TB of space, not 11TB) and 1TB of space missing (reducing actual capacity to 9TB) due to not all the 3TB drive capacity being used - so I'd echo the comment to check if vertical expansion has taken place - Vertical expansion in this case takes at least one reboot after the horizontal expansion (adding the disks to the array). One one of my NVX units, it worked with one reboot, on the other it did take two.
- Thanks for all of the information from you guys......I have rebooted twice and I see the vertical expansion taking place. Thanks!
