Lvm??

Hello Guys,

I have the following partition being made on the Linux System:

Code:

Filesystem            Size  Used Avail Use% Mounted on
/dev/hda6             5.7G  5.5G     0 100% /
/dev/hda5             494M  8.2M  461M   2% /boot
tmpfs                 314M     0  314M   0% /dev/shm
/dev/hda9             251M  251M     0 100% /home
/dev/hda8             494M   65M  405M  14% /var


LABEL=/                 /                       ext2    defaults        1 1
LABEL=/boot             /boot                   ext2    defaults        1 2
devpts                  /dev/pts                devpts  gid=5,mode=620  0 0
tmpfs                   /dev/shm                tmpfs   defaults        0 0
LABEL=/home             /home                   ext2    defaults        1 2
proc                    /proc                   proc    defaults        0 0
sysfs                   /sys                    sysfs   defaults        0 0
LABEL=/var              /var                    ext3    defaults        1 2
LABEL=SWAP-hda7         swap                    swap    defaults        0 0

How can I create LVM on top of that?
Pls Help with the steps by steps.

Thanks in advance,

The default way to go (and the only one I know) with LVM is that you first create LVM system with logical volumes and so on, and then create the partitions inside the LVM setup, not the other way around.

Your easiest start with LVM would be to reinstall your operating system, selecting manual partitioning option and creating LVM that way. Anything else is probably more difficult.

Note: some distributions offer an option to automatically partition using Logical Volume Management. That way you don't have to touch the partitioning tool manually if you are fine with the default options. In addition the setup of some distributions (Ubuntu alternate setup disc?) might offer an option to create a disk-encrypted LVM-based installation.

While LVM can be useful when one needs contiguous space spanning multiple drives most of its other features can be done without it. IF it fails it can be a real bear to recover. What exactly are you trying to accomplish by switching to LVM?

Can You please help with the steps by steps of LVM commands.
As I am new to the Linux,I want to be in safe place without screwing up my system

/dev/mapper/VolGroup00-LogVol05

                      6.8G  128M  6.3G   2% /var

Pls Help

Since you are new to linux I will ask again. What are you trying to accomplish by switching to LVM?
