RedHat EX200 Exam - Topic 2 Question 112 Discussion

One Logical Volume is created named 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.
A) Explanation: 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

I’m pretty sure you have to run `fsck` to ensure the filesystem is consistent, but I’m not clear on the exact size limits for reducing the volume.

I feel like we did a similar question in class where we had to resize a filesystem, but I can't recall if we used `resize2fs` before or after `lvreduce`.

I think the command to check the size is `lvdisplay`, but I’m a bit confused about the order of the commands for resizing.

Okay, I think I've got a plan. First, I'll check the current size of the logical volume, then reduce the filesystem, and finally reduce the logical volume itself. Gotta be careful not to lose any data!

Reducing the size and keeping the data intact? That's like magic! I wonder if the exam proctors will accept a 'ta-da!' as the answer.

Haha, maybe the exam proctors will appreciate the 'ta-da!' moment if you successfully resize the logical volume.
