How To Configure Swap Partition And Swap File Over Lvm And Lvm Over Raid 5 In Redhat Linux

In This Tutorial We Are Going To Learn How To Configure Swap Partition And Swap File Over Lvm And Lvm Over Raid 5

Now firstly We Have To Create Raid Then We Have To Create LVM And Then We Have To Create Swap Partition And Swap File Over Lvm

Here You Can Check The Diagram 

For Creating Lvm Here We Have To Create First 3 Partition Which Type Is Raid 

Step -1 Here First We Have To Create Raid Partition

fdisk -l
fdisk /dev/sda
n {for New Partition}
Select Partition 2
t {For Change The Type Of Partition}
fd {For Creating Raid Partition}
p {For Check Partition Is created Or Not}
w {For Save}
Partprobe /Dev/Sda {For Refresh}

fdisk -l
fdisk /dev/sda
n {for New Partition}
Select Partition 3
t {For Change The Type Of Partition}
fd {For Creating Raid Partition}
p {For Check Partition Is created Or Not}
w {For Save}
Partprobe /Dev/Sda {For Refresh}

fdisk -l
fdisk /dev/sda
n {for New Partition}
Select Partition 4
t {For Change The Type Of Partition}
fd {For Creating Raid Partition}
p {For Check Partition Is created Or Not}
w {For Save}
Partprobe /Dev/Sda {For Refresh}

If You Do Any Change In Hard Disk Then You Have To Run Command Partprobe Then Give The Hard Disk Name Where You Do Change 

Now Or Partition Is Created Now We Have To Create Raid 5 Using This Partition

Step -2 Here Is The Coading Of Creating Raid 

mdadm –create /dev/md0 –level=5–raid-devices=2 /dev/sda2 dev/sda3 /dev/sda4

Now Our Second Portion Of Create Raid Is Complete Nov We Have To Create Lvm

Step -3 Here Is the Coading Of Create Lvm 

pvcreate /dev/sda2 /dev/sda3 /dev/sda4 
pvs
vgcreate vg00 /dev/sda2 /dev/sda3 /dev/sda4
vgs
lvcreate -L+1G -n Lv1 vg00
lvs
lvcreate -L+1G -n Lv2 vg00 
lvs

Step -4 Now We Have To Create Swap Partition Over Lvm In Lv1 

Mkswap /dev/vg00/lv1
free-m
Swapon /dev/vg00/lv1

Step -5 Now We Have To Create Swap File Over Lvm In Lv2

dd if=/dev/zero of=/hacking bs=1M count=500
Free-m
Mkswap /hacking
swapon /hacking

This Is How All We Configure Swap Partition And Swap File Over Lvm And Lvm Over Raid 5
