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:

1 2 ... 271 272 273 274 275 276 277 278 279 280 281 ... 745 746
