ubuntu graphical lvm
I loaded the graphical LMV application but it will not launch.
Is there any good readme on using the LVM. I read the man pages but was looking for a graphical interface if possible. This is the program I loaded. Logical Volume Management System-config-lvm provides a graphical interface to the LVM tools (and related utilities, including fsck and resize2fs) which is good for non-emergency storage administration. It enables you to manage your logical volume and filesystem configuration with a few mouse clicks, and it prevents potentially- disasterous command-line mistakes such as reducing a logical volume size before reducing the filesystem contained within that volume. (One word of warning: system-config-lvm does not recognize RAID elements as being in use, and therefore lists them as "Unitnitialized Entities". If you are using a LVM-on-RAID configuration, system-config-lvm will let you wipe out RAID elements by making them into PVs. Be careful!) |
Hello unix1adm :)
Dunno about graphical front ends but here are two good LVM links: http://dev.riseup.net/grimoire/storage/lvm2/ and http://tldp.org/HOWTO/LVM-HOWTO/ I guess LVM is fairly sysadmin hardcore stuff so there wouldn't be much demand for GUIs and they will not be heavily used/tested -- scary!

I tried to run this from cmd line and get the following. I uninstalled and reinstalled same issue. Also what would the cmd line lvm packages be. I dont seem to have them loaded. WHen I look for lvm in the package manager it does not show any to install. I know in redhat/fedora there are rpms. I want to create a new logical volume with the xtra space i have.

system-config-lvm and rpm are both specific to a Red Hat and related distros, a family of which Ubuntu is not a part. As Charles said, there's probably not a lot of demand for graphical LVM management tools, as users of lvm are generally 'sysadmin hardcore' types who don't mind working without a GUI or new users who go with the defaults in Fedora/Ubuntu/others. Perhaps this is an exciting opportunity for you to shed your discomfort with administering a system sans-GUI?

Well the tool is there but does not work. Ok I can live with that. What is the command line to use in Ubuntu. I do prefer cmd line over gui but just thought it would work since it was in the package manager for Ubuntu.

Charles was also kind enough to provide a couple links which I have checked and can tell you have all the info you need. If you want to get a quick look at all the available commands (perhaps so you can read their manpages), try tab-completing 'lv', 'pv', and 'vg'.

Ill check the links again but my systems does not appear to have lvm commands installed So I was trying find out what I was missing. Or may be I am uysing the wrong commands for Ubuntu. These are the one I use in RH.
lvm ? No such command. Try 'help'. # lvm --help No such command. Try 'help'. # lvm -h No such command. Try 'help'. |
lvcreate
/proc/misc: No entry for device-mapper found Is device-mapper driver missing from kernel? Failure to communicate with kernel device-mapper driver. /proc/misc: No entry for device-mapper found Is device-mapper driver missing from kernel? Failure to communicate with kernel device-mapper driver. Incompatible libdevmapper 1.02.27 (2008-06-25)(compat) and kernel driver striped: Required device-mapper target(s) not detected in your kernel Run `lvcreate --help' for more information. |
It looks like something is missing from the kernel. I can do a man on the commands so they are loaded on the system.

If you really want the definitive answer on Ubuntu LVM GUI etc, try the Ubuntu form here at LQ or Ubuntu home website.

But, frankly, I think it's a lot more convenient to use the alternate installer for this kind of task. |
