Course Scipion in the cloud: practical advance aspects

Working with EBS

In this practical work we will perform the typical operations with EBS volumes

Create an EBS volume:

• Login to AWS console with your user (i2pc-course-x)
• Go to EC2 services
• Select Volumes on the left side menu
• Check the availability zone of your instance
• Select 'Add tags' and add a tag called Name equal to 'i2pc-volume-x' (replace x by your user number)
• Click on 'Create Volume'
• Set Volume size to 1 GB and Availability Zone to the one of your instance (IMPORTANT)

• Click on 'Create volume' button

Attach a volume to an instance

• Select your volume (named i2pc-training-volume-x)
• Click on 'Actions' and select 'Attach volume'
• Wait till it finishes attaching (refresh)
• Go to your 'Instances' and start your instance (i2pc-machine-x)
• Wait till it finishes starting and login through VNC
• Format the volume (attached to xvdf) sudo mkfs -t ext4 /dev/xvdf
• Create a directory where to mount it, for instance sudo mkdir /volume-2
• Mount it sudo mount /dev/xvdf /volume-2

Detach a volume from an instance

• First you should stop the machine
• Click on 'Actions' and select 'Detach volume'
