I think you should check the filesystem type before resizing.

The size range is 200-260 MB, so 220 MB is perfect!

I definitely recall needing to run `e2fsck` before resizing, but I can't remember if I should run it on the mounted or unmounted filesystem.

I'm a bit confused about the size limits. The question says between 200-260 MB, but I thought we could only reduce it to exactly 220 MB.

I practiced a similar question where we had to reduce a logical volume, and I remember using `resize2fs` before `lvreduce`. I hope that's the right order here too!

No problem, I've done this kind of thing before. I'll just follow the steps in the explanation and double-check the final size to make sure it's within the required range.

Alright, I've got this. The key is to use the resize2fs command to shrink the file system, and then use lvreduce to reduce the logical volume size.

I wonder if they have a 'Reduce Volume, Increase Headache' option on the exam. That's the one I'd probably end up choosing.
