#AWS- Attaching and mounting EBS/NFS/EFS volumes: This gives information on the creation of ebs voln and mounting them on servers, it also shows how to connect multiple network file system (nfs) using efs

Your ebs volume created an the ec2 created must be in the same availbilty zone AZ for you to be able to mount the ebs voln

[ec2-user@ip-10-0-0-23 ~]$ history 1 exit 2 clear 3 df -h 4 lsblk 5 ls / 6 clear 7 lsblk 8 df -h 9 clear 10 mkdir /app 11 sudo mkdir /app 12 clear

13 lsblk =
14 sudo file -s /dev/xvdf #(To check the status to know if the file is formated or not)

15 sudo mkfs -t xfs /dev/xvdf #(Make directory to create a file system)

16 clear 17 sudo mkdir /data #(Create another mount point called data) 18 la /app 19 ls /app 20 ls /data 21 df -h

22 sudo mount /dev/xvdf /data #(mounting the created ebs volume on data directory) 23 clear 24 lsblk

25 sudo mount /dev/xvdf /app (mounting the created ebs volume on app directory) 26 lsblk 27 df -h reboot / init 6 / init 0 /
28 sudo cp /etc/fstab /etc/fstab.orig #(This command is to save make the mounted ebs volume to stay after reboot ie to be permanent) 29 history

Volume expansion - vertical [4gb-->7gb] Volume expansion - horizontal [v1=8g, v2=7g, v3=6g]

Traditional volume mgt and LVM use to require SystemsAdmin skills to perform. Today cloud computing skills are required

Lambda functions:

If we have upto 75% volume usage increase vol by 20%
Note to enable your cross region when creating snapshot Life cycle management cross account aws account1 = email/password database servers
aws account2 = email/password
backup data in

cross region

from a snapshot, we can create: Snapshots are stored in S3 and help in creating

1. volumes
2. images = AMI : Community

File storage system : It is a network file system managed by AWS efs volume = file storage:(Network file Systems) remember that nfs port is : 2049 Required mounting sudo yum install nfs-utils sudo mkdir efs
sudo mount -t nfs4 -o nfsvers=4.1,rsize=1048576,wsize=1048576,hard,timeo=600,retrans=2,noresvport fs-0506f72fa378122f3.efs.us-east-1.amazonaws.com:/ efs
