Setting up LVM on suse

Setting of LVM is as done below

1. First of all create physical volume

# pvcreate /dev/device [/dev/device] ..

2. Next step is to create volume group on physical volume

# vgcreate vg-name /dev/device [/dev/devices]..

3. Next is to create logical volume

# lvcreate -L size [K|M|G|T] -n lv-name vg-name

where K – kilobytes

M – megabytes

G- gigabytes

T – terabytes

lv-name – is logical volume name

vg-name – is volume group name

4. Next is to create file system on that device

# mkfs.ext2 /dev/vg-name/lv-name

This will create ext2 file system

5. Next is to create mount point

# mount /dev/vg-name/lv-name /mountpoint

If you want to resize the file system , use the following command

# lvextend -L +512MB /dev/vg-name/lv-name

This will extend the lv by 512 MB
