How to make the additional volume available to your operating system for use by Raj Gupta

First create a volume  you want to attach

Now attach this volume to your EC2 server

Now logging in to your linux EC2 server and run the below command

[root@ip-172-31-88-83 ~]# lsblk
NAME    MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
xvda    202:0    0   8G  0 disk
└─xvda1 202:1    0   8G  0 part /    -----This is root volume
xvdf    202:80   0   1G  0 disk     ------This is our additional volume which are not mount till now

If the output shows simply data, as in the following example output, there is no file system on the device and you must create one.

[root@ip-172-31-88-83 ~]# sudo file -s /dev/xvdf
/dev/xvdf: data

Use the mkfs -t command to create a file system on the volume.

[root@ip-172-31-88-83 ~]# sudo mkfs -t xfs /dev/xvdf
meta-data=/dev/xvdf              isize=512    agcount=4, agsize=65536 blks
         =                       sectsz=512   attr=2, projid32bit=1
         =                       crc=1        finobt=1, sparse=0
data     =                       bsize=4096   blocks=262144, imaxpct=25
         =                       sunit=0      swidth=0 blks
naming   =version 2              bsize=4096   ascii-ci=0 ftype=1
log      =internal log           bsize=4096   blocks=2560, version=2
         =                       sectsz=512   sunit=0 blks, lazy-count=1
realtime =none                   extsz=4096   blocks=0, rtextents=0

Use the mkdir command to create a mount point directory for the volume

[root@ip-172-31-88-83 ~]# sudo mkdir /data

Use the following command to mount the volume at the directory you created in the previous step.

[root@ip-172-31-88-83 ~]# sudo mount /dev/xvdf /data

Now our Volume are mount and ready for use to write to the volume
[root@ip-172-31-88-83 ~]# lsblk
NAME    MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
xvda    202:0    0   8G  0 disk
└─xvda1 202:1    0   8G  0 part /
xvdf    202:80   0   1G  0 disk /data
