RedHat EX200 Exam - Topic 5 Question 104 Discussion

Resize the logical volume vo and its filesystem to 290 MB. Make sure that the filesystem contents remain intact.Note: Partitions are seldom exactly the same size requested, so a size within the range of 260 MB to 320 MiB is acceptable.

I thought you could just grow the filesystem without unmounting!

290 MB? That seems oddly specific, is that really necessary?

Just use lvextend and resize2fs, super straightforward!

I think the acceptable range is important, but I’m worried I might miscalculate the size when using `lvreduce`.

I feel like I’ve seen a question similar to this where we had to check the filesystem first with `e2fsck`. Should we do that here too?

I remember practicing with `resize2fs`, but I’m confused about whether I should run it before or after `lvreduce`.

I think we need to use `lvreduce` to shrink the logical volume, but I'm not entirely sure about the exact syntax.

This looks like a classic LVM resizing question. I'd start by checking the current size with `df`, then use `lvextend` to increase the volume size. After that, I'd run `resize2fs` to expand the filesystem to match. Should be able to get this done pretty quickly.

Okay, I think I've got a plan here. First I'll use `e2fsck` to check the filesystem, then `umount` the volume, `resize2fs` to resize the filesystem, and finally `lvreduce` to shrink the logical volume. Gotta make sure the contents stay intact though, that's the tricky part.

Hmm, this one's got me a little stumped. I know I need to resize the logical volume and filesystem, but I'm not sure of the exact commands to use. I'll have to review my notes on LVM management before attempting this.

I think I've got a good handle on this. I'd start by checking the current size of the logical volume and filesystem using `df -hT`. Then I'd use `lvextend` to increase the size of the logical volume by 100 MB, and `xfs_growfs` to expand the filesystem to match. Should be pretty straightforward.
