# Resize System Volumes

The size of the system volumes (inside volume group `vgroot`), are automatically set on a rather small size at the initial installation.

Note that due to the limitations of XFS a volume can only be increased, not be shrunk.

## Get Available Space and Volume Sizes

To check how much space is still available, use `pvs` and look for the volume group `vgroot`:
```
[root@lxdev00 ~]# pvs
  PV         VG      Fmt  Attr PSize   PFree 
  /dev/sda2  vg_root lvm2 a--  <62.94g <5.19g
[root@lxdev00 ~]# 
```

Then `lvs` gives the sizes of the volumes inside:
```
[root@lxdev00 ~]# lvs
  LV         VG      Attr       LSize   Pool Origin Data%  Meta%  Move Log Cpy%Sync Convert
  lv_home    vg_root -wi-ao---- <31.44g                                                    
  lv_openafs vg_root -wi-ao----   2.00g                                                    
  lv_root    vg_root -wi-ao----  12.31g                                                    
  lv_tmp     vg_root -wi-ao----   2.00g                                                    
  lv_var     vg_root -wi-ao----   8.00g                                                    
  lv_var_log vg_root -wi-ao----   2.00g                                                    
[root@lxdev00 ~]# 
```

## Extend System Volume

This can be done in Hiera with the `vgroot::path` key where for each volume which should be increased a new minium size can be set:

```
vgroot::path:
    lv_root: 15GB
    lv_var_log: 3GB

```

This is then applied on the next puppet run, you may trigger one as `root`:

```
puppet agent -t
```
