<pre>2. Describe the process of use LVM to create two partitions on drive sdb (1 and 2), make them into physical volumes, 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 a partitionthe logical volume by 1GB and resize the filesystem the file system to fill it. <pre>
1st COMMAND: fdisk /dev/sdb
2nd COMMAND: pvcreate /dev/sdb1 /dev/sdb2
3rd COMMAND: vgcreate seneca /dev/sdb1 /dev/sdb2
4th COMMAND: lvcreate -n home --size 500M seneca
5 th 5th COMMAND: mkfs.ext3 /dev/seneca/home  6th COMMAND: mount /dev/seneca/home /mnt  7th COMMAND: e2label /dev/seneca/home myhome  8th COMMAND: vgextend seneca /dev/sdb2  9th COMMAND: lvextend -L +1G /dev/seneca/home  10th COMMAND: resize2fs /dev/seneca/home  +------[ Volume Group (VG) - lvmdsk ]------+ | +--[ PV - hda1 ]---+ +--[ PV - hdb1 ]--+ | | | PE PE PE PE PE PE| | PE PE PE PE PE | | | +------------------+ +-----------------+ | | | | | | | | | | +-----------------+ | | | | +----------------+ | | | | | | | | | +-[ LV - var ]-+ +-[ LV - home ]-+ | | | LE LE LE LE | | LE LE LE LE | | | +--------------+ +---------------+ | +---------------------------------------------+ source: http://focalinux.cipsga.org.br/guia/inic_interm/ch-disc.htm </pre>[[Image:lvm.png]]<pre>3. Steps to compile the linux kernel  1st make mrproper 2nd make oldconfig 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.
6 th COMMAND: mount #lvreduce /dev/seneca/home /mnt-L 40M
7 th COMMANDPS: e2label wrong values/dev/senecaparameters may render file system unavailable ref:RHCE exam Book </home myhomepre>
8 th COMMAND: vgextend seneca /dev/sda6<pre>5. Kick Start Procedure
9 th COMMAND: lvextend -L+1G Install Fedora- sudo yum -y install k3b isomaster- use k3b to rip Fedora Installation DVD into ISO- use isomaster to copy file "/devroot/senecaanaconda-ks.cfg" from local Fedora partition into the ISO file, put it in root directory in the ISO file, "/homeks.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.. ^^
10 th COMMAND: resize2fs /dev/seneca/home
