Question

30: One Logical Volume is created as myvol under vo volume group and is mounted. The Initial Size of that Logical Volume is 400MB. Make successfully that the size of Logical Volume 200MB without losing any data. The size of logical volume 200MB to 210MB will be acceptable.

Explanation

Answers:

First check the size of Logical Volume: lvdisplay /dev/vo/myvol
Make sure that the filesystem is in a consistent state before reducing:

fsck -f /dev/vo/myvol

Now reduce the filesystem by 200MB.

resize2fs /dev/vo/myvol 200M

It is now possible to reduce the logical volume. #lvreduce /dev/vo/myvol -L 200M
Verify the Size of Logical Volume: lvdisplay /dev/vo/myvol
Verify that the size comes in online or not: df -h
