How do I expand /root on CentOS7?

/dev/mapper/cl-root   50G   44G  6.9G  87% /
devtmpfs             3.9G     0  3.9G   0% /dev

@DustinB3403 Anyway to do this keeping it all on one drive? I can add space to the end of the drive very easily.

There may be a way to do so, that was the top google result for this query.

Here is another topic marked as solved.. Which he backs up the partitions, removes them, adds them back and finally expands the partition.

There are multiple ways. You have to expand each piece. Start with growing the disk. Then grow the volume. Then grow the file system.
