Redundancy in Lab 17.3 (losetup and parted)

Hi,

That's a good question! Not sure what distro you are, but I did a test case on CentOS 8. As the way that parted works, it needs to be instructed to make filesystems on the partitions after they are created in step 3. If you do 'fdisk -l' just after step 3, you will see they marked as 'linux' partitions, but you won't be able to mount them, because the OS will say there isn't a filesystem in each of these partitions. So you will need to make them as in step 6.

The man parted(8) page says the following:

mkpart part-type [fs-type] start end
Make a part-type partition for filesystem fs-type (if specified), beginning at
start and ending at end (by default in megabytes). part-type should be one of
"primary", "logical", or "extended".

So, in the command in step 3, we are specifying the fs-type (we could not and it should work anyway). But for some reason we need to format they anyway after that, or they won't mount.

Many regards,
Luis.

Good point, I'll check if we can avoid specifying the fs-type parameter in the first command.

Regards,
Luis.

Hi coop,

I just did a test case on CentOS 8, and I didn't specify the fs-type in step 3, as the man parted(8) says this parameter is optional. Then I gave filesystem to the partitions as shown in step 6, and the partitions showed up correctly in the fdisk -l output. So, it looks it's right to say that specifying the fs-type in step 3 is unnecessary.

Many regards,
Luis.
