RedHat EX200 Exam - Topic 3 Question 101 Discussion

Actual exam question for RedHat's EX200 exam

Question #: 101
Topic #: 3

Adjust the size of the Logical Volume.

Adjust the size of the vo Logical Volume, its file system size should be 290M. Make sure that the content of this system is complete.

Note: the partition size is rarely accurate to the same size as required, so in the range 270M to 320M is acceptable.

AExplanation:
Addition
df -hT
lvextend -L +100M /dev/vg0/vo
Lvscan
xfs_growfs /home/ //home is the mounted directory of the LVM, this step just need to do in the practice environment, and test EXT4 does not need this step.
resize2fs /dev/vg0/vo// use this command to update in examination.
df -hT
OR
Subtraction
e2fsck -f/dev/vg0/vo
umount /home
resize2fs /dev/vg0/vo // the final required partition capacity is 100M lvreduce -l 100M /dev/vg0/vo
mount /dev/vg0/vo/home
df -hT

Wait, can you really reduce the size that much without losing data?

Seems straightforward, but I’d double-check those commands.

I thought the resize2fs command was only for EXT4?

Totally agree, but make sure to check the range!

Just a heads up, the file system size should be around 290M.

I’m pretty confident about using `lvscan` to check the logical volumes, but I’m not sure if I should use `e2fsck` before resizing.

I feel like I need to double-check the commands for unmounting the filesystem before resizing. Did we cover that in the labs?

I think we did a similar question where we had to adjust a logical volume size, but I can't recall if we used `xfs_growfs` or just `resize2fs` for EXT4.

I remember practicing with `lvextend` and `resize2fs`, but I'm a bit unsure about the exact order of commands.

Alright, this seems doable. I'll start by verifying the current size, then use the appropriate LVM commands to resize the volume. Gotta be careful not to go outside that 270-320M range they mentioned. Shouldn't be too tricky if I take it step-by-step.

Whoa, resizing an LVM, that's a new one for me. I better read the instructions carefully and make sure I don't accidentally delete any data. Maybe I'll start by checking the partition size and then go from there.

Okay, let me think this through step-by-step. First I'll use `df -hT` to see the current size, then use `lvextend` or `lvreduce` to adjust it, and finally run `resize2fs` to update the file system. Gotta make sure the content stays intact too.

Hmm, this looks like a straightforward LVM resizing task. I'll need to check the current size, then either extend or reduce the volume as needed to reach the 290M target.
