Configuration lvm proxmox

[keny090]

Hello, I just installed proxmox 5.0. I would like to be able to reduce the size of the partition lvm.

sda                            8:0    1 931.5G  0 disk
├─sda1                         8:1    1     1M  0 part
├─sda2                         8:2    1   256M  0 part
└─sda3                         8:3    1 931.3G  0 part
  ├─pve-swap                 253:0    0     8G  0 lvm  [SWAP]
  ├─pve-root                 253:1    0    96G  0 lvm  /
  ├─pve-data_tmeta           253:2    0   104M  0 lvm
  │ └─pve-data-tpool         253:4    0 811.3G  0 lvm
  │   ├─pve-data             253:5    0 811.3G  0 lvm
  │   ├─pve-vm--100--disk--1 253:6    0    12G  0 lvm
  │   ├─pve-vm--102--disk--1 253:7    0    32G  0 lvm
  │   └─pve-vm--101--disk--2 253:9    0    50G  0 lvm
  └─pve-data_tdata           253:3    0 811.3G  0 lvm
    └─pve-data-tpool         253:4    0 811.3G  0 lvm
      ├─pve-data             253:5    0 811.3G  0 lvm
      ├─pve-vm--100--disk--1 253:6    0    12G  0 lvm
      ├─pve-vm--102--disk--1 253:7    0    32G  0 lvm
      └─pve-vm--101--disk--2 253:9    0    50G  0 lvm

I would like to reduce the pve-data partition. To be able to create an ext4 partition of 300gb. But I do not know how to do it

Thanks

you can do this with the standard lvm/lvmthin tools

see

man lvm
man lvmthin
