Linux partitioning cheatsheet

Check current state:

df -h

Sample output:

Filesystem            Size  Used Avail Use% Mounted on
/dev/sda1             440G   46G  372G  12% /
none                  5.9G  260K  5.9G   1% /dev
none                  5.9G     0  5.9G   0% /dev/shm
none                  5.9G   64K  5.9G   1% /var/run
none                  5.9G     0  5.9G   0% /var/lock
none                  5.9G     0  5.9G   0% /lib/init/rw
/dev/sdb1             459G  198M  435G   1% /data1

The new disk (no partitioning)

ls /dev/[sh]d*

/dev/sda  /dev/sda1  /dev/sda2  /dev/sda5  /dev/sdb  /dev/sdb1  /dev/sdc

fdisk for check specific drive

fdisk -l /dev/sdc
