# 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
|
|
```
