I have a CentOS VM (on a windows host, managed with virtualbox) that ran out of disk space.

I extended the virtual disk size, then used gparted to assign the new space to the existing partition

Then I used lvextend to assign halves of the free space to /dev/cl/home and /dev/cl/root

However df show that the /dev/mapper/cl-home and /dev/mapper/cl-root haven't grown into the now available space even after a reboot.

What am I missing ? Any tutos I found about extending existing logical volumes considered the job done with lvextend...

df gives :

/dev/mapper/cl-root    39G     37G  1,2G  98% /
/dev/mapper/cl-home    19G     13G  5,7G  70% /home
/dev/sda1             976M    672M  238M  74% /boot

and lsblk :

NAME        MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
sda           8:0    0  150G  0 disk 
├─sda1        8:1    0    1G  0 part /boot
└─sda2        8:2    0  149G  0 part

  └─cl-home 253:2    0 61,6G  0 lvm  /home

and lvdisplay

resize2fs (for ext4) or xfs_growfs (for xfs) are used to resize the file system to fully use the logical volume alloted.
