I love LVM2 and xfs

My hard disk was constantly seeking (scratchy noises coming out of my PC) but looking at the output of htop did not show anything special, until I got an error message from Iceweasel that /tmp was full. df displayed that:

david@apoll:/tmp$ df -h
Dateisystem Größe Benut Verf Ben% Eingehängt auf
/dev/mapper/default-system 10G 10G 40K 100% /

(For the non-geeks: My main hard disk partition was almost full).

Thank god I use the Linux LVM, so I simply did this to get more free space:

david@apoll:~$ sudo lvextend -L+5G /dev/default/system
Extending logical volume system to 15,00 GB
Logical volume system successfully resized
david@apoll:~$ sudo xfs_growfs /
(...)
data blocks changed from 2621440 to 3932160
david@apoll:~$ df -h /
Dateisystem Größe Benut Verf Ben% Eingehängt auf
/dev/mapper/default-system 15G 9,7G 5,4G 65% /

I love that LVM allows you to change partitions on the fly and that xfs allows you to actually resized mounted (=in use) partitions.
