[SOLVED] Extending an LVM partition

Recently did a fresh install of Arch, using encryption with LVM on top and Gnome as the desktop. Soon after I had a pop up warning on logging in about there only being 100Mb left on /usr. So I extended the /usr group by 1Gb with the command: " lvextend -L4G /dev/base/usr ", the original size was 3Gb.

So now lvscan shows me this:

[root@kaminari /etc]# lvscan
  ACTIVE            '/dev/base/tmp' [500.00 MiB] inherit
  ACTIVE            '/dev/base/var' [2.93 GiB] inherit
  ACTIVE            '/dev/base/usr' [4.00 GiB] inherit
  ACTIVE            '/dev/base/root' [1000.00 MiB] inherit
  ACTIVE            '/dev/base/home' [390.62 GiB] inherit

Great it's apparently 4Gb, but I still get this pop up warning about there being not enough room on /usr.

 [root@kaminari /etc]# df -h /usr
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/base-usr  2.9G  2.7G   93M  97% /usr

The above shows something isnt quite right!  Where am I going wrong?

Re: [SOLVED] Extending an LVM partition

You have extended the logical volume. Now you need to extend the filesystem.
