Creating LVM Partition on a newly added HDD Drive

 

Creating LVM Partition on a newly added HDD

 

We are going to follow the step-by-step procedures mentioned in the picture.

Step 1: Insert physical internal HDD into the server.

#fdisk -l ( use this command to list the added HDDs)

Make sure that added HDD is replicating in the server.

#fdisk /dev/sdb ( use this path to enter into the sdb HDD)

ü  once get into the path à let’s do the partition on the dev/sdb HDD

Step 2: Creating Partition to the  newly added HDD

ü  As mentioned in the above chart we have created the partition in the name of  /dev/sdb1.

ü  While creating itself we have to check whether the system format is in Linux LVM or some other format.

ü  If its system is in some other format needs to change the format as a Linux LVM.

Hence kindly follow the below steps to convert Linux LVM format :

 

# m (Enter the command for the help)

# t (Enter the option to change a  Partition’s system id)

# t ( Once the option is entered you get the output like Selected Partition  1)

Here u can see yellow marked;

enter L (command to list all Hex-codes)

# 8e (option  to select Linux LVM format)

Now format has been changed to Linux LVM

# w (Enter the command to save the above changes)

Step 3:  Creating Physical Volume: 

# pvcreate  /dev/sdb1 (enter this command to create a physical volume on the /dev/sdb1 partition)

Once create u will get the messages like below one.

#pvdispaly (Enter the command to display Physical Volume just now you created)

Now u have created PV on dev/sdb1.

 

Step 4:Creating Volume Group

# vgcreate  example_vg (need to provide volume group name) /dev/sdb1 (partitioned path)

#vgdisplay example_vg (vg name) which you given

Step 5 : Creating Logical Volume

#lvcreate -n example_lv - -size  3.6TB example_vg

(Enter a command to create a logical volume(similar kind of name which you have given before for the vg to identify easily)

--size needs to provide based on your HDD and vg group name )

Once the above config is done you can see the message like LV is created.

#lvdisplay (Enter a command to verify you have created the LV)

(Here itself you can verify the LV Path, LV Name, and VG Name)

 

 Step 5 : Creating File System

#mkfs.xfs /dev/example_vg/example_lv (enter a command to create a file system). While creating a file system you need to provide a volume group name and logical volume  name(which you created in the server)

Till now  we have followed the step-by-step configuration  and configured LVM on HDD

 

Step 6: mounting File System to Mount point

Before mounting the file system, we need to create a directory

Note: In my server, I have created a directory named popular_backup under /home

#mount /dev/pop_vg/pop_lv  /home/popular_backup

(Enter the command with the /dev/vg name/lv name(which you gave and mount point)

Before mounting the file system on the mount point

       

After mounting the file system on the mount point

Once the file system is mounted in the mounting point.

Note: you should update the mounting details in the fstab directory like the below snap.

Otherwise when you reboot the server-mounted point will be unmounted to avoid this need updated in fstab file. 

#vi /etc/fstab

/dev/pop_vg/pop_lv     /home/popular_callrecord_backup  xfs defaults    0 0
