creating logical volume

can someone please verify the syntax on the following commands:
lvcreate -L150G -n/dev/VolGroup01/u08 VolGroup01
mkfs.ext3 /dev/VolGroup01/dev/VolGroup01/u08

a vgdisplay shows:
VG Name VolGroup01
VG Size 2.27 TB
Alloc PE /Size 38400 /150.00 gb
Free PE /Size 556453 /2.12 TB

an lvdisplay for an existing logical volume on the same volume group shows:
LV Name /dev/VolGroup01/u02
VG Name VolGroup01

it's been a while since i had to create a new logical volume and i'd rather not screw it up... thanks.

The only thing that is different from your syntax compared to what I normally use is the name option. I will usually do a one word name and it will end up on the volume groups path in /dev/. Try just setting -n to u08 and see if you get the results you are looking for.

The name should look something like so:

[root]# lvcreate –L drivesize –n mountname VolGroup01
[root]# lvcreate –L 150G –n u08 VolGroup01


[root]# mkfs.ext3 /dev/VolGroup01/u08

It should automatically add the /dev/VolGroup01 for the lvcreate. Also you have 2.12 TB free - are you not wanting to use that space?
