hi

I have a Volume Group named "VolumeGroup002"
and I have 3 Logical Volumes in that Volume Group 30 GB each

/dev/VolumeGroup002/Backup
/dev/VolumeGroup002/UserData
/dev/VolumeGroup002/HiddenData

now I want to extend all of them to 20GB size my question is how can I find out how much space I have left in my "VolumeGroup002"? so I can determine if I can extend those or I need to get another HDD to get more space.

I am not able to find a command that lets me know the available space in my "VolumeGroup002"

Correct me if I am wrong but the only way I can do this is

df -h and after that some lvm command like vgs or vgdisplay

is that the only way?

thanks a lot
