TOS 6 - how much disk space used?

[subfiver]

I got an F4-212 + 2x8tb drives; when I set it up I found TOS6 wasn't supported, so factory reset and sent it back

Replaced with F4-423, installed the same drives, 5hrs to 'synchronise' then I did a manual update to TOS 6.0.530.

Prior to update Vol 1 (raid1) was showing 100-odd k used space, post TOS6 it's showing 372.05 Gb used and my nominal 8Tb drives in Raid 1 are showing a capacity of only 7.21Gb.

Is this normal for TOS6 and can I recover any of that 372gb ?

PS: I haven't "used" the NAS, nor installed any apps, tho' I notice that in App Center some apps are shown "Install" and some "download" which implyes some of these apps. are on Vol1 somewhere ....

\Volume1\@apps
App folders may remain after an app is removed
App settings may be lost converting from Tos5.1 to >=Tos6.0.420

I discovered by accident that TOS's volumes configured with 5% reserved space for root (common thing on linux).

On large volumes there is a significant loss of free space.
Vendor should respond with solution.
