Re: Physical Disk Size

Could someone tell me a command i can run on my Redhat machines to find out
the physical disk size of the hard disk in the machine without having to
take the disk out and look at it , this is because  i have some machines
that are 18/36/72/73 gig and need to know which ones they are. I have run a
fdisk to show the partitions but i am unsure if all of the machines have
been configured to use all of the disk so there must be a command i can run
to just check this out?
Any help would be much appreciated.

Fdisk tells you the size of the disk, as well as the partitions.

# fdisk -l

Disk /dev/sda: 72.9 GB, 72999763968 bytes
255 heads, 63 sectors/track, 8875 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1          13      104391   83  Linux
/dev/sda2              14        1288    10241437+  82  Linux swap
/dev/sda3            1289        8875    60942577+  8e  Linux LVM

On the first line of output it says the disk is 72.9GB.
