Hello, Could you, please, explain, in console of my Digital ocean droplet with Ubuntu 18 I run command to know how many of disk space I have # df -HT Filesystem Type Size Used Avail Use% Mounted on udev devtmpfs 504M 0 504M 0% /dev tmpfs tmpfs 104M 791k 103M 1% /run /dev/vda1 ext4 26G 6.0G 20G 23% / tmpfs tmpfs 517M 8.2k 517M 1% /dev/shm tmpfs tmpfs 5.3M 0 5.3M 0% /run/lock tmpfs tmpfs 517M Laravel Tutorial - Filemanager 0 517M 0% /sys/fs/cgroup /dev/vda15 vfat 110M 3.6M 106M 4% /boot/efi tmpfs tmpfs 104M 0 104M 0% /run/user/0 Code (markup): I suppose that /dev/vda1 is my working partition I have 20 GB of free disk space I can use for my applications. Is it so? Now on my laptop there is Kubuntu 18 too, so I suppose that /dev/vda15 that is boot partition. I have general understanding what is it. 1) Just interesting : what are the rest of partitions and have I anyway to pay attention on them or take care about them ? 2) If there is safe way to restart Ubuntu 18 on Digital ocean droplet ? In some cases I modify some config files, say of apache 2(I work with php) and I know that to apply my changes I need to run sudo service apache2 restart Code (markup): But In some cases I do not know, if my changes are applied and I would prefer to restart my system as I usually do on my laptop... Thanks!
