I am new to SUSE, my /dev/mapper/system-root is used up. I tried to extend it with: _lvextend -L + 510G /dev/mapper/system-root_ Afterward, I can see that system-root is now 570 G with lsblk: _# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 1.1T 0 disk ??sda1 8:1 0 1.1T 0 part ??system-root 254:0 0 570G 0 lvm / ??system-swap 254:1 0 2G 0 lvm [SWAP]_ However, df still shows 60 GB, and I still get “disk full” message, How can I extend /dev/mapper/system-root ? _/usr/sap/HXE/HDB90\> df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/system-root 60G 60G 0 100% / /dev/mapper/system-root 60G 60G 0 100% /home_ Thanks in advance! ---

Hi Is lvextend all you did? If so have a read here: [https://suse.com/c/linux-lvm-logical-volume-management/](https://suse.com/c/linux-lvm-logical-volume-management/) What do you have running on this system? If it’s just a test system, for / it should be enough for the operating system if running btrfs? Are you running btrfs and snapper? If so then have a read here: [https://en.opensuse.org/SDB:BTRFS](https://en.opensuse.org/SDB:BTRFS)
