Subvolume size is not cumulative with disk size

You can use either --disk-use-available or ZPOOL module

[askovpen]

$ NO_CONFIG=1 fastfetch -S Disk --disk-use-available
Disk (/mnt/d1): 256.00 KiB / 5.18 TiB (0%) - zfs

@askovpen Just use the zpool module as mentioned:

$ NO_CONFIG=1 fastfetch --structure Disk
Disk (/zfs-pool): 128.00 KiB / 784.95 GiB (0%) - zfs

$ NO_CONFIG=1 fastfetch --structure zpool
Zpool (zfs-pool): 50.25 GiB / 928.00 GiB (5%, 1% frag) - ONLINE

ZFS and BTRFS have dedicated modules for a reason.
