Surprised they didn’t mention checking the volume group status first!

I think both options are missing the mkfs step for formatting.

Wait, did they just mix up the mount point in option A?

I feel like both options are close, but I’m leaning towards B since it explicitly formats the filesystem, which seems important.

I’m a bit confused about the fstab entry. Should it be /dev/datastore/database instead of /dev/datastore?

I think option B looks familiar; it has the mkfs.ext3 command, which we definitely covered in class.

I remember we practiced creating logical volumes, but I'm not sure if I got the extent size right in the commands.

Okay, I've got this. The key here is to use the firewall-cmd command, which is the standard command-line tool for managing the firewall. And the --query-service option will let me check if the HTTP service is allowed. Easy peasy!

Okay, let's think this through. The stable, controllable environment is a plus, but those third-party controls are definitely going to be the biggest challenge.
