Working with File Systems
PRACTICAL
EXERCISE
PART 1
1.- Find information about every
mass storage device installed in your system.
2.- Find the device file
associated to your hard disk. Display information about
every partition in your hard disk, showing partition, number
of blocks and file file system type.
3.- Find for every mounted file system in your computer the
following information: a) Device file where the file system
is storaged, b) File system type, c) File system size in
human readable format, d) The amount of disk used and
available
in human readable format and e) mounpoint (directory)
connected to the file system.
4.- Create a new SATA hard disk called
w7alt, linked to SATA Port 1.
Start your Linux system
and install gparted. Format
the new SATA disk with
the NTFS file system.
5.- Mount manually the new file
system a new directory called /windows/w7. If that
directory does not exist then, make it.
6-
Donwload the following iso
image:http://www.tinycorelinux.net/5.x/x86/release/Core-5.2.iso
. Shutdown your system. Add
the newly downloaded iso image to your systema as a
new IDE storage device connected to the secondary
master socket and configured as a master. Boot your
system again. Check if your newly connected storage
device has been mounted during
the boot process. If your new block device was mounted then,
unmount it.
7.- Check of block device file
systems connected to your your computer.
Check another time the list of mounted file
systems in your computer. What is the difference?.
8.- Mount the file system in the ISO image on a directory called /media/cdrom_core52. If that directory does not exist then, make it.
9.- Gain
access to your recently mounted CDROM changing to
/media/core_52 and make a list of its contents. Change to
the directory called boot and list its contents. Copy
core.gz in the recently mounted NTFS file system, which should be accessible through
the /windows/w7 directory. Check if
core.gz has been succesfully copied.
10.- Change to /windows/w7.
Create a directory called "test". Check if "test" has
been succesfully copied.
11.- Stay in /windows/w7. Try
to unmount your NTFS file system. Chek if you are able to
unmount the filesystem while you are working in the file
system. Change to /windows. Try it again. Does it work?.
Why?.
12.- Gain access to your DVD. Create a directory
called "test". Has
it been succesfully created. Why?. What is
the message displayed by the system?
13.- Unmount your DVD.
14.- Display a summarized and human readable report about
the file space usage of folders /home, /usr and /bin in
your computer.
15.- Display now a summarized and readable report
about your home directory. Display this information in
a non summarized way. Redirect this information to
a file called duhome.txt. in your home directory.
Display this information in a non summarized and
non human readable way.

Help: a) http://www.tldp.org/HOWTO/Partition/fdisk_partitioning.html
b) http://www.debuntu.org/how-to-create-a-filesystem-within-another-partition-s-file
16.- With the help of b) --> Create a file called virtualfs00 in the /media
directory using the command dd and working with
/dev/zero. The file size will be 512MB. Make a ext3 file
system in that file. Mount the file system on
/media/virt00 (if /media/virt00 does not exist then, make
it). Check if the new file system has been mounted. Gain
access to the new file system and check if
there are folders and files. Create a new folder called test. Unmount the new file system. Check if the new file
system has been mounted. Check if you can find the
test folder in /media/virt?. What is happennig?. Mount the file system again. Check if you can find the
test folder in /media/virt?. What is happennig?.
17.- With the help of a) --> Create a file called virtualfs01 in the /media directory using the command dd and working with /dev/zero. The file size will be 512MB. Working with fdisk, make 3 partitions. The first one will be a 128MB/active/ext3 paritition. The second one will be a 128MB/FAT32 partition. The third one will be a 258MB/NTFS partition.
18.- Umount /media/virt00. Remove virtualfs00 and virtualfs01.
