Q75. CORRECT TEXT

There are three Disk Partitions /dev/hda8, /dev/hda9, /dev/hda10 having size 100MB of each partition. Create a Logical Volume named testvolume1 and testvolume2 having a size 250MB.

Mount each Logical Volume on lvmtest1, lvmtest2 directory.

Answer and Explanation:

Steps of Creating LVM:

1. pvcreate /dev/hda8 /dev/hda9 /dev/hda10

àpvdisplay command is used to display the information of physical volume.

2. vgceate test0 /dev/hda8 /dev/hda9 /dev/hda10

àvgdisplay command is used to display the information of Volume Group.

3. lvcreate -L 250M -n testvolume1 test0

à lvdisplay command is used to display the information of Logical Volume.

4. lvcreate -L 250M -n testvolume2 test0

5. mkfs -t ext3 /dev/test0/testvolume1

6. mkfs -t ext3 /dev/test0/testvolume2

7. mkdir /lvtest1

8. mkdir /lvtest2

9. mount /dev/test0/testvolume1 /lvtest1

10. mount /dev/test0/testvolume2 /lvtest2

11. vi /etc/fstab

/dev/test0/testvolume2 /lvtest2 ext3 defaults 0 0

/dev/test0/testvolume1 /lvtest1 ext3 defaults 0 0

To create the LVM( Logical Volume Manager) we required the disks having '8e' Linux LVM type.

First we should create the physical Volume, then we can create the Volume group from disks belongs to physical Volume. lvcreate command is used to create the logical volume on volume group. We can specify the size of logical volume with -L option and name with -n option.

1. First check the size of Logical Volume: lvdisplay /dev/vo/myvol

2. Make sure that the filesystem is in a consistent state before reducing:

# fsck -f /dev/vo/myvol

3. Now reduce the filesystem by 200MB.

# resize2fs /dev/vo/myvol 200M

4. It is now possible to reduce the logical volume.

#lvreduce /dev/vo/myvol -L 200M

4. Verify the Size of Logical Volume: lvdisplay /dev/vo/myvol

5. Verify that the size comes in online or not: df -h
