Hi
I'm having the following situation:
# zpool list
NAME SIZE ALLOC FREE EXPANDSZ FRAG CAP DEDUP HEALTH ALTROOT
rpool 3.62T 3.51T 119G - 54% 96% 1.02x ONLINE -


rpool 3.51T 2.35M 104K /rpool
rpool/ROOT 1.47G 2.35M 96K /rpool/ROOT
rpool/ROOT/pve-1 1.47G 2.35M 1.47G /
rpool/data 3.49T 2.35M 96K /rpool/data
rpool/data/vm-101-disk-1 3.49T 2.35M 3.49T -
rpool/swap 17.0G 3.01G 14.0G -

Due to some mistakes, we've got the disk almost filled by a vm.

As far as i can see, there are 119G free in rpool. any idea how i can increase rpool/ROOT to 10G ? As the partition is full, i'm having trouble fixing other issues.

If you want more free space in rpool/ROOT/pve-1 then

1. Turn off swap.
2. Remove rpool/swap
3. Create rpool/swap with less space like 5G
4. Format swap and mount

Result -> free space for zfs pool rpool
