create logical volume

Yaroki — Thu, 24 Nov 2011 08:58:25 GMT

Hello,

When I try to create lv

# lvcreate -L 12 /dev/vg01/data

I receive the following message:

lvcreate: Volume group "/dev/vg01/data" does not exist in the "/etc/lvmtab" file.

What should I do?

HP-UX, B.11.11

BR,

Yali

You need to create the vg01 on a new disk/LUN first. Once you have the VG, you can create a LVOL.

You used a wrong syntax.

If you want to create a 12 MB LV named /dev/vg01/data to a VG named vg01 that already exists, the correct syntax would be:

lvcreate -L 12 -n data /dev/vg01

With your original syntax, the command would have tried to create a new LV with a default name (i.e. "lvol1" if there are no other LVs) to a VG named /dev/vg01/data. So the full name of the proposed LV would have been something like /dev/vg01/data/lvol1... but since /dev/vg01/data is not a valid VG name, the command told you such a VG does not exist.
