In this example we will work through shrinking logical volume /var/centos/var from 10GB to 5GB.īefore working through the resizing process it’s important you first understand some basic concepts around physical volumes, volume groups, logical volumes, and the file system. As of CentOS 7 the default file system is XFS which is not currently possible to shrink, this example is working with the ext4 file system. Note: In this example we are working in CentOS 7, some commands may differ in different Linux distributions. See here if you’re instead trying to do the opposite and expand an LVM volume.
Here we show you how to shrink an LVM volume or partition in Linux by first resizing the file system followed by resizing the logical volume.
