Linux - Reduce filesystem size

On Linux you can reduce the size of a filesystem using the command line.

Firstly you check the filesystem:

# fsck -f <logvolname>

Then you resize the filesystem:

# resize2fs <logvolname> <size>

You then reduce the log volume size:

# lvreduce <logvolname> <size>

Finally you mount the log volume:

# mount <logvolname>
