[SOLVED] command to add a volume in an existing LVM VolGroup

x201s · 05-23-2011, 11:55 AM

I created LVM partition when I had access to GUI. Now the GUI has been removed and I need to create a new volume out of what was left untouched in LVM. I don't know any command to create a volume out of existing volume group.

pvdisplay shows as follows:

Code:

--- Physical volume ---
  PV Name               /dev/sda2
  VG Name               VolGroup00
  PV Size               439.45 GB / not usable 16.42 MB
  Allocatable           yes 
  PE Size (KByte)       32768
  Total PE              14062
  Free PE               3118
  Allocated PE          10944

the current volumes are:

Code:

/dev/mapper/VolGroup00-LogVolHome
/dev/mapper/VolGroup00-LogVolUsr
/dev/mapper/VolGroup00-LogVolTmp
/dev/mapper/VolGroup00-LogVolVar

I want to add
/dev/mapper/VolGroup00-LogVolData using the rest of the space of VolGroup00

How do I do that using command line?

Hello,

The command you need to create a logical volume is lvcreate. Look at the man page for specifications or have a look at this great guide to LVM for beginners.

Kind regards,
