New to Ubuntu, have some questions. I am running 18.04 in a VM on Esxi 6.5, where I am running Docker containers. One of the apps I am running in docker is causing me some issues, one of which could be related to free disk space issues. The VM is configured for 30GB, thin provision.
Fdisk shows the disk at total 30GB as expected, but when I run df -h I am not seeing /dev/sda3. Also, what are the /loop devices?
Device Start End Sectors Size Type
/dev/sda1 2048 4095 2048 1M BIOS boot
/dev/sda2 4096 2101247 2097152 1G Linux filesystem
/dev/sda3 2101248 62912511 60811264 29G Linux filesystem

I don’t understand why there is this discrepancy, could someone kindly explain?
