lvm resize and use the remaining extra space

df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/vg_12-lv_root
                       50G  1.2G   46G   3% /
tmpfs                 7.8G     0  7.8G   0% /dev/shm
/dev/sda1             485M   52M  408M  12% /boot
/dev/mapper/vg_12-lv_home
                       94G  188M   89G   1% /home


I want to resize /dev/mapper/vg_12-lv_home

lvresize -r -L 100M /dev/mapper/vg_12-lv_home

The above resizes it to 100 megabytes, you could specify G for gigabytes too, of course you can't make it too small if you have used more space than the size you specify, it will throw an error.
resize2fs 1.41.12 (17-May-2010)
resize2fs: New size smaller than minimum (92233)

fsadm: Resize ext4 failed
  fsadm failed: 1
  Filesystem resize failed.

*Changing it to 1G made it work.


Now I want to resize my root to use the maximum possible space:

lvresize -r -l +100%FREE /dev/mapper/vg_12-lv_root
Notice instead of using -L which specifies a specific size, I've used "-l +100%FREE", it makes vg_12-lv_root use 100% of the available free space on the physical volume I freed by resizing the lv_home above
