3. Creating an HDLM Environment
252
Physical volume "/dev/sddlmad2" successfully created
5. Create a volume group.
In the following example, the command creates the
vg01
volume group by using
the physical volumes
/dev/sddlmad1
and
/dev/sddlmad2
:
# vgcreate vg01 /dev/sddlmad1 /dev/sddlmad2
Volume group "vg01" successfully created
6. Create the logical volume.
In the following example, the command creates the logical volume (
lvol1
: 100
MB) by using the
vg01
volume group:
# lvcreate -L 100M -n lvol1 vg01
Logical volume "lvol1" created
7. Create a file system.
The following example shows how to use the
mke2fs
command to create a file
system on the
lvol1
logical volume:
# mke2fs /dev/vg01/lvol1
Filesystem label=
OS type: Linux
Block size=1024 (log=0)
Fragment size=1024 (log=0)
25688 inodes, 102400 blocks
5120 blocks (5.00%) reserved for the super user
First data block=1
13 block groups
8192 blocks per group, 8192 fragments per group
1976 inodes per group
Superblock backups stored on blocks:
8193, 24577, 40961, 57345, 73729
Writing inode tables: done
Writing superblocks and filesystem accounting information:
done
This filesystem will be automatically checked every 38 mounts
or 180 days, whichever comes first. Use tune2fs -c or -i to
override.
8. Create the directory to which the logical volume is to be mounted.
The following example shows how to create the
/mnt/lvol1
directory:
