Chapter 9 Lab 9.3

NYCJacob

I got through lab 91 and 9.2 fine.

I was not sure what was meant by 'better still, zero it out'

I deleted the imagefile and did the dd command to create it again and then did a mkfs as in lab 9.1

There was no loop devices on my system so my parted command was:

sudo parted -s /dev/loop0 mklabel msdos

This gave me the following error

Warning: Error fsyncing/closing /dev/loop0:Input/output error

Not sure what I did wrong.

I also tried this on a fedora system and after the parted command I got
Parted: invalid token: primary

coop

did you do

losetup -f

first (to show first available loop device?)

also do

ls -l /dev/loop

Everything has worked fine for me on Fedora 22

I am having trouble with Step 5:

With Linux CentOS 3.10.0-123.el7.x86_64 #1 SMP Mon Jun 30 12:09:22 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

sudo ln -s /dev/mapper/loop1p1 /dev/loop1p1

I get a return of:
ln: failed to create symbolic link ‘/dev/loop1p1’: File exists

But ls -la /dev/mapper/loop1* returns:
ls: cannot access /dev/mapper/loop1*: No such file or directory

With Linux Ubuntu-Server 3.16.0-51-generic #69~14.04.1-Ubuntu SMP Wed Oct 7 15:32:41 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

sudo kpartx -lv /dev/loop1
sudo: kpartx: command not found

and

sudo ln -s /dev/mapper/loop1p1 /dev/loop1p1
ln: failed to create symbolic link ‘/dev/loop1p1’: File exists

I tried apt-get install kpartx and util-linux but no packages are found.

Linux opensus-server 3.16.6-2-desktop #1 SMP PREEMPT Mon Oct 20 13:47:22 UTC 2014 (feb42ea) x86_64 x86_64 x86_64 GNU/Linux

ls -l /dev/mapper/loop*
ls: cannot access /dev/mapper/loop*: No such file or directory
jes001@opensus-server-64:~> ls -l /dev/mapper/loop1*
ls: cannot access /dev/mapper/loop1*: No such file or directory



Any ideas?
