4Tb shows only 2790 gb allocated space
Replaced one of 3Tb HDD for a new one 4TB. It shows correct 3726 gb size but allocated space as the same 2790 gb after resync. Latest Radiator , firmware 4.2.8 any ideas ?

Thx. There were relevant changes to the firmware around 4.2.15, so its important to know that you are current.
The volume will not expand if you have only installed a single 4 TB drive - you need have at least two installed for single-redundancy xraid to expand. So that is your situation.
There are two limits to expansion with 4.2.x firmware, and it is possible that you have reached one of them.
-a volume will not expand over 16 TiB. Note this is the volume size, not the raw disk capacity, and that the units are TiB, not TB. 6x3TB single redundancy gives a 15 TB volume (which is ~13.6 TiB).
-a volume cannot grow more than 8 TiB from its starting point. The starting point is the size from the last factory reset (or initial install if you've never done a factory reset).
You aren't at the first limit, but it is possible you are reaching the second. If so, inserting a second 4 TB drive also won't expand. Do you recall your initial disk configuration?

Thanks a lo! I performed a default reset, then installed the second 4Tb and now it is fine almost 15 Gb )))
