The system-config-lvm is the first GUI LVM tool which was originally released as part of Red Hat Linux. It is also called LVM GUI because it is the first one. Later, Red Hat also created an installation package for it. So system-config-lvm is able to be used in other Linux distributions. The installation package includes RPM packages and DEB packages.
The system-config-lvm only supports lvm-related operations. Its user interface is divided into three parts. The left part is tree view of disk devices and LVM devices (VGs); the middle part is the main view which shows VG usage, divided into LV and PV columns.

The different versions of system-config-lvm are not completely consistent in the organized way of devices. Some of them show both LVM devices and non-lvm devices (disk), the others show LVM devices only. I have tried two versions, one shows LVM devices existing in the system, namely PV/VG/LV only, no other devices; The other can display non-lvm disks and PV can be removed in disk view.
Hmm couldnt do it with gnome-disk-util so ended up going with CLI thanks to this really useful page I found - -lvm-volumes-centos-rhel-7-system-storage-manager.html Opens a new window so hopefully this will be useful for anyone searching and finding this thread.
tag_hash_107 The newest version of Ubuntu (12.10 at the time of this writing), now ships with LVM as an integral part. That is good news, because on previous releases, while you could install the system-config-lvm utility, you would also have to install about 180MB worth of missing LVM stuff with it. This would make the "just get in and out with a live CD" use case a bit slower. Moreover you had to issue a manual command so that all of the functions of the utility, namely the filesystem re-sizing, would work.
As you can see, the centos pool has been successfully expanded from 7.5GB to 8.5GB. At this point, however, disk volumes (e.g., /dev/centos/root and /dev/centos/swap) that exist in the pool are not utilizing the added space. For that, we need to expand existing LVM volumes.
We can confirm that the size of /dev/centos/root volume has increased from 6.7GB to 7.2GB. However, this does not mean that you can immediately utilize the extra space within the file system created inside the volume. You can see that the file system size (FS size) still remains as 6.7GB.
I installed an old version of system-config-lvm from reposcope. Then i had to make sure to run on Xorg, not Wayland -- log out and choose "Ubuntu on Xorg" from the gear menu, then log in. After that i could start it just fine from the dash or command line.
I'm trying to resize a couple of my LVM partitions. I have one that is 850GB (/dev/mapper/cl-home) and one that is 50GB (/dev/mapper/cl-root). I'd like to make it so that cl-home is 750GB and cl-root is 150GB. I resized the partitions so that if I use system-config-lvm and look at the size cl-home appears as 750GB and cl-root is 150GB. However, if I do a df -h, both cl-home and cl-root appear as their old sizes (850GB and 50GB respectively). How do I make it so that I am able to see and use the resized partitions?
CentOS 4 includes system-config-lvm, a graphical tool for configuring Logical Volume Manager (LVM). system-config-lvm allows users to create volume groups from physical disk drives and disk partitions on a local machine, creating flexible and extensible logical volumes that are treated as normal physical disk space by the system.
Let's say that you have run out of disk space on your centos3 VM, and you need more space on the root file-system in order to host more web-pages, or to support a larger database. What are your options? Getting a replacement hard-drive would probably require re-installation of the operating system and/or backing up and restoring data on the old hard disk.
We take for granted that a file-system must be mounted (for example the root partition) in order for a Linux system to be usable upon system start-up. This was create automatically for the /archive mount point automatically when we used the system-config-lvm utility in the previous investigation. We need to learn now to do this manually by editing or adding an entry in the /etc/fstab file. The /etc/fstab (file system table) contains entries to mount various file systems automatically upon start-up of the Linux system.
From the above output we can see that there is a physical volume (PV) named /dev/sda2 and the PV is a partition of the first disk drive. We can also see that there is a volume group (VG) named centos on this physical volume. 17dc91bb1f
