How do I create a new Logical Volume / Partition ?
We will be creating a new logical volume named DATA and mounting this on a new directory called DATA.
First of we will create the logical volume, then we will create a file system on the Logical Volume. Once complete we will create a new directory called DATA.
lvcreate -L 145G -n DATA vg0
mkfs.ext3 /dev/Vg0/DATA
mkdir /DATA
Then add the following line to the /etc/fstab file,
/dev/vg0/DATA /DATA ext3 defaults 1 2
We can then mount /DATA,
mount -a
You can now check to make sure you changes have been successful.
[[email protected] ~]# df -kh
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/vg0-root 3.9G 588M 3.2G 16% /
/dev/mapper/vg0-var 15G 278M 14G 2% /var
/dev/mapper/vg0-usr 9.7G 623M 8.6G 7% /usr
/dev/mapper/vg0-home 1.8G 146M 1.6G 9% /home
/dev/hda1 99M 18M 77M 19% /boot
tmpfs 502M 0 502M 0% /dev/shm
/dev/mapper/vg0-DATA 143G 188M 136G 1% /DATA
Please Note : You system will pre-allocate 10% of the total size of your new Logical Volume.
