Example Midterm Test Questions
</pre>
<pre>2. Describe the process to create two partitionson drive sdb (1 and 2), make them into physical volumevolumes, create a volume group, named seneca containing sdb1 and a logical volume (500M) named home. Format the logical volume as an ext3 filesystem, and label it, myhome. Then extent the volume group and logical volume by 1GB and then resize the filesystemthe file system to fill it. <pre>
1st COMMAND: fdisk /dev/sdb
2nd COMMAND: pvcreate /dev/sdb1 /dev/sdb2
3rd COMMAND: vgcreate seneca /dev/sdb1
4th COMMAND: lvcreate -n home --size 500M seneca
7th COMMAND: e2label /dev/seneca/home myhome
8th COMMAND: vgextend seneca /dev/sda2sdb2
9th COMMAND: lvextend -L+1G /dev/seneca/home
10th COMMAND: resize2fs /dev/seneca/home

3. Steps to compile the linux kernel
3rd make menuconfig
4th make
5th make modules_install </pre> <pre> 4. Steps to reduce the LV (logical Volume)  1. To reduce the volume the file system has to reduced first. In this example the original size of LV is 240 MB and we have to reduce it by 200. Means the resulting LV size would be 40 MB (a)File system has to unmounted before reducing #umount /mnt (b)make sure the file system is in consistence state before reducing  # fsck -f /dev/seneca/home (c)reduce the size by 200MB  # resize2fs /dev/seneca/home 40M (d)Now we can reduce the LV.   #lvreduce /dev/seneca/home -L 40M PS: wrong values/parameters may render file system unavailable ref:RHCE exam Book </pre> <pre>5. Kick Start Procedure - Install Fedora- sudo yum -y install k3b isomaster- use k3b to rip Fedora Installation DVD into ISO- use isomaster to copy file "/root/anaconda-ks.cfg" from local Fedora partition into the ISO file, put it in root directory in the ISO file, "/ks.cfg"- open "ks.cfg" find the line... "bootloader --location=mbr --driveorder=sda,sdb --apppend="rhgb quiet""- change to "bootloader --location=sdb --driveorder=sda,sdb --apppend="rhgb quiet""-save and add to the image ISO, make sure the name is "ks.cfg" on ISO Image. -if u're not running with root, use root to copy it to avaliable directory and make sure it's readable for your current user-in your image list, open /isolinux/isolinux.cfg-find "label linux" and edit the line "append initrd=initrd.img" to "append initrd=initrd.img ks=cdrom"-save "isolinux.cfg" and add to the image ISO- use k3b to burn iso image to a new DVD- boot the target PC with the new Fedora installation DVD\- in boot prompt, press "c" to add boot option- type "ks=cdrom" to let installation read the ks.cfg from DVD rom- sit back and have a cup of tea.. ^^
''PS: now we don't use make modules anymore, I saw a guy using "make rpm" instead of using only "make"''
