How to Check Disk space usage on the ESX

To check the free space on an ESX service console partitions:
1.Log in to the ESX service console as root from either an SSH session or directly from the console of the host.
2.Type df -h.

The output appears similar to:

Filesystem Size Used Avail Use% Mounted on
/dev/sda2 4.9G 3.0G 1.6G 66% /
/dev/sda1 99M 18M 77M 19% /boot
none 145M 0 145M 0% /dev/shm
