i need to know the available space that i have on my linux machine, so i used df -h command
and it gave me the following:
/dev/sdb2 21G 5.8G 15G ..... /
udev 2.0G 152K 2.0G ...... /dev
/dev/sdb3 444G 2.2G 442G ..... /home
i need to know if those are the storage devices that i have on the machine?
another thing is: executing iostat -k generated the following:
sda 0.00 0.00 ....
sdb 4.95 0.12
so what are sda and sdb and what are sdb2, sdb3 and udev ?
which of those are my storage devices?
thanks in advance
