Hi Jagadesh,

#lvcreate -L test -n lvol3 /dev/vg00

shout be

#lvcreate -L 100 -n lvol3 /dev/vg00

where 100 is the size in Megabytes.

To create a 100 meg lvol named test:

lvcreate -L 100 -n test /dev/vg00

The lvol3 in your command should not be there. The above command will create: /dev/vg00/test and /dev/vg00/rtest. If this lvol is to contain a filesystem, you'll need to create an empty directory structure using newfs as in:

newfs /dev/vg00/rtest

The L option should be defined as the size of Logical volume.

check the man pages of lvcreate.

Thanks

Hi Jagadesh,

These is syntex error in command.
You say logical volume "test: in first line and in command you given name lvol3.
if you want to create logical volume name test correct syntex is like this.

#lvcreate -L -n test /dev/vg00

-L option is for specifing Logical volume's size in MB.
