Hi all. I have a "perfect server" setup on a VPS where i'm running out of space. From the cloud panel at my provider I have been able to change disksize from 20 GB to 30 GB. Now I need to resize this in Debian 8. Code: df -h Filesystem Size Used Avail Use% Mounted on /dev/dm-0 19G 15G 3.5G 81% / udev 10M 0 10M 0% /dev tmpfs 200M 4.6M 196M 3% /run tmpfs 499M 0 499M 0% /dev/shm tmpfs 5.0M 0 5.0M 0% /run/lock tmpfs 499M 0 499M 0% /sys/fs/cgroup /dev/vda1 228M 47M 170M 22% /boot tmpfs 100M 0 100M 0% /run/user/0 I tried to follow this guide: http://www.microhowto.info/howto/increase_the_size_of_an_ext2_ext3_or_ext4_filesystem.html with no success. From console the umount /dev/dm-0 command does not change anything. It is still mounted to / Can some one help me how to proceed? Thanks in advance BR Bjarne
