Red Hat ES v3 - Determine what space is left on disk after disk driud

[Ratzie]

I have built my Red Hat ES v3 server, with 2 identical drives that were mirrored RAID1 (each slice).

[root@server etc]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/md5 2.1G 257M 1.8G 13% /
/dev/md1 97M 15M 78M 16% /boot
none 504M 0 504M 0% /dev/shm
/dev/md3 981M 17M 915M 2% /tmp
/dev/md2 3.9G 1.4G 2.3G 38% /usr

I just realized that I am missing a partion for /var. I know that I have left over space on the disk, how can I check? How do I create another raid device then assign it to /var after the fact/

there are two ways:

1) fdisk /dev/your_disk_device_name


2) there is "Disk Managemanet" utility under desktop "Start" [== RedHat] menu

Oops! I'm sorry- GUI "disk management" utility doesn't allow to add new partitions.

So IMHO you have only fdisk /sfdisk/parted
