How can I extend existing filesystem without reboot?

Hi.
Storage for a CentOS 7 virtual machine seems to be completed full.
Code:[root@linux ~]# df -h
Filesystem Size Used Avail Use% Mounted on
devtmpfs 7.7G 0 7.7G 0% /dev
tmpfs 7.7G 84K 7.7G 1% /dev/shm
tmpfs 7.7G 773M 7.0G 10% /run
tmpfs 7.7G 0 7.7G 0% /sys/fs/cgroup
/dev/mapper/ol_linux-root 26G 26G 20K 100% /
/dev/sda2 1014M 188M 827M 19% /boot
/dev/sda1 200M 9.8M 190M 5% /boot/efi
tmpfs 1.6G 36K 1.6G 1% /run/user/54321
tmpfs 1.6G 4.0K 1.6G 1% /run/user/42
tmpfs 1.6G 0 1.6G 0% /run/user/0What I probably need, is to allocate more space to this "/dev/maper/ol_linux-root" file system. Am I right? How can I do this?
