reduce local-lvm (pve/data) and extend root

[j0nghee]

Hi, i have this lvs:
LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert
data pve twi-aotz-- 429.71g 4.81 0.26
root pve -wi-ao---- 112.00g
swap pve -wi-ao---- 8.00g

first: how can i access data? Can i mount it in a folder?
second: how can i take gb from data and increase the size of root?

I'm a beginner, so sorry for mistakes! Thanks so much.

first: data is your thin pool volume in which you have can create your VMs and containers in. It can't get mounted on its own

second: Unfortunately LVM thin pools don't support reducing yet
