I.8 Creating a Logical Volume
To create a logical volume within the volume group, use the
lvcreate
command with
the
-L
option to specify the size of the logical volume in megabytes. The logical
volume size should be a multiple of the physical extent size. In the following example,
a logical volume of 4092 Mbyte is created:
Both character and block device files for the new logical volume are created in the
volume group directory:
Applications should use these names to access the logical volumes. Unless you specify
otherwise, HP-UX creates names in the form shown in the example. To specify custom
names for logical volumes, see
vgcreate
(1M).
I.9 Creating an HP-UX File System
The following command creates a file system on the logical volume created in the
previous steps.
I.10 Mounting the File System Manually
The process of incorporating a file system into the existing directory structure is
known as mounting the file system. The files, although present on the disk, are not
accessible to users until they are mounted.
1. Create a directory to use as the mount point for your new file system:
2. To mount your file system, type the following:
# lvcreate -L 4092 /dev/vg02
# ls /dev/vg02
group lvol1 rlvol1
# /sbin/newfs -F vxfs /dev/vgmynewvg/rlvol1
# mkdir /usr/local/myfs
# mount /dev/vgmynewvg/lvol1 /usr/local/myfs
