Ty for your help

Resize2fs is a utility to resize file systems. From the terminal, run "man resize2fs". It will tell your more about what it is and how to use it. Alternatively, you can read the man pages here.

resize2fs is useful if you expand the partition a file system resides upon, or of you bit-copy it to a new drive. Although it can be used to either expand or shrink an ext2-based file system (including ext3/ext4 ones), shrinking one is not recommended as you may well lose data. It is always recommended to backup your data before you use this sort of tool.

What is it that you are trying to do?

resize2fs is an utility that is used for online extension of the filesystem.

Suppose you have extended your LV then doing resize2fs /mount_point will increase you FS size as per the size of the logical volume.
