I thought we could go up to 190 MB, that's surprising!

Just use lvextend -L 160M instead.

You can only extend to 160 MB, not 190 MB.

I’m pretty sure we need to ensure the logical volume is within the specified limits, but I can’t recall if 190 MB is valid for this case.

I feel like the command should specify the size correctly, but I’m confused about the range allowed after extending.

I think we did a similar question where we had to use lvextend first and then resize2fs, but I’m not clear on the exact size parameters.

I remember we practiced extending logical volumes, but I’m not sure if the command syntax is correct for the size limit.

Okay, let me see if I can break this down. ISO 26262 is definitely related to functional safety, not security. And I believe it is based on the general IEC 61508 standard, but tailored for the automotive domain. I think C is the right answer, but I'll double-check my notes to be sure.

Option D, a peer review of the requirements, seems like a solid choice to me. Getting a fresh set of eyes on the requirements could help identify any ambiguities or areas that need clarification.
