Hey,
you know what this symbol means. This is the symbol that means
that you've worked through another milestone.
Congratulations! You now know all about disks and partitions.
We've seen the lsblk command where we can list out our block devices.
Not only that,
we've seen how we can create our own block devices.
Either using the dd or fallocate command,
we can go through and create raw files and link
them to loop devices with losetup.
When it comes to a physical disk or one of our disk files,
we can also work with parted. Working with parted, we can go through and
create partitions. Parted is what we looked at in this section.
However,
you can use other tools such as fdisk. To reread the partition table,
we can use partprobe. If we need a little bit more security, then we
can go through and encrypt a partition.
Now the idea of encrypting a partition or encrypting a disk is
encrypting the underlying structure, so even any filesystem that is
laid upon it is going to be encrypted.
This is normally limited to devices that are likely to be leaving
the server room, so probably not our servers, but think about it
for our portable devices and laptops.
But this is only the beginning.
We need to touch much more upon the idea of filesystems, and that's
what we're going to do next when we jump out to our next module, which is entitled Managing Linux Filesystems.
