Just to clarify the volume size. With XRAID/RAID-5 the volume capacity for 4x4TB is 12 TB. The other 4 TB are used for RAID parity blocks (which is what the system uses to rebuild a disk when it is replaced).
But the NAS reports sizes in TiB (1024*1024*1024*1024 bytes), not TB (1000*1000*1000*1000 TB). 12 TB is the same as 10.9 TiB.
2.26/10.9 is about 20% (slighty more, but there could be some accounted for space).
The warnings are quite conservative. Generally I expand my volume when free space drops to about 15%, and I haven't had any issues with stability.
FWIW, I do leave quotas on, so I can see the space used by every share.
