Ah, okay, thanks. When I do that, I get
[billw@dom0 Desktop]$ sudo lvs
LV VG Attr LSize Pool
Origin Data% Meta% Move Log Cpy%Sync Convert
pool00 qubes_dom0 twi-aotz-- 906.96g
52.49 28.32
root qubes_dom0 Vwi-aotz-- 906.96g
pool00 2.14
swap qubes_dom0 -wi-ao---- 7.55g
and so forth.
Does that mean that my drive is actually 81% full with only 450 GB of VMs? I
sure hope not. That's over 50% overhead!
Cheers
