In order to practice for the RHCSA at home, I took an old Dell Latitude E6500 with 4GiB of RAM and purchased a 500GiB hard drive on which I could install CentOS 7 with a server GUI as the base operating system and them multiple virtual machines using KVM with which to experiment and learn.My package selection for the install was a Server GUI installation. I partitioned the hard drive with 1 GiB of swap, 500 MiB on a standard partition for the /boot, and 30 GiB for the root partition.
I also created a 60 GiB partition for /home, and then allocated everything that remained (375.27 GiB) to /var. The reason for giving some much space to /var is that the default KVM / qemu setup on CentOS 7 places virtual hard drive images in /var/lib/libvirt/images, so I wanted plenty of space available for multiple images.
After the install finished I wanted to see what the partitions looked like, so I ran
$ sudo yum install system-storage-managerand then
$ sudo ssm listwhich revealed the following:
----------------------------------------------------------------- Device Free Used Total Pool Mount point ----------------------------------------------------------------- /dev/sda 465.76 GB PARTITIONED /dev/sda1 500.00 MB /boot /dev/sda2 0.00 KB 465.27 GB 465.27 GB centos ----------------------------------------------------------------- -------------------------------------------------------- Pool Type Devices Free Used Total ---------------------------------------------------- centos lvm 1 0.00 KB 465.27 GB 465.27 GB ---------------------------------------------------- -------------------------------------------------------------------------------- Volume Pool Vol size FS FS size Free Type Mount point -------------------------------------------------------------------------------- /dev/centos/swap centos 1.00 GB linear /dev/centos/root centos 30.00 GB xfs 29.99 GB 26.73 GB linear / /dev/centos/home centos 60.00 GB ext4 60.00 GB 55.88 GB linear /home /dev/centos/var centos 374.27 GB ext4 374.27 GB 349.02 GB linear /var /dev/sda1 500.00 MB xfs 493.73 MB 293.59 MB part /boot --------------------------------------------------------------------------------
