UseCase: Launch an AWS cloud9 environment that has added EBS of 500GB. This environment will be extensively used to build and publish dockers by developers.

So I did start an m.5.large instance-based environment and attached an EBS volume of 500GB.

Attachment information: i-00xxxxxxb53 (aws-cloud9-dev-6f2xxxx3bda8c):/dev/sdf

This is my total storage and I do not see 500GB volume.

On digging further, it looks like the EBS volume is attached but not at the correct mount point.

Question: What should be the next step in order to use this EBS volume?

Question: What should be done in order to make use attached EBS for docker building?

Question: What should be the most efficient instance type for docker building?

  1. Tyoe df -hT here you will find the Filesystem type of root if it is xfs or ext4
  2. If say root (/) is xfs, run the following command for the 500 GiB Volume $ mkfs -t xfs /dev/nvme1n1 If root (/) is ext4, $ mkfs -t ext4 /dev/nvme1n1
  3. Create a directory in root say named mount $ mkdir /mount
  4. Now mount the 500 GiB Volume to /mount $ mount /dev/nvme1n1 /mount
  5. Now it will be mounted and can viewed in df -hT
  6. Also make sure to update the /etc/fstab so mount remains stable if there is a reboot
  7. To update first find UUID if 500 GiB EBS Volume $ blkid /dev/nvme1n1 Note down the UUID from the output
  8. Now go to /etc/fstab using editor of your choice $ vi /etc/fstab
  9. There must be an entry already for /, update for mount and save the file, (note replace xfs with ext4 if filesytem is ext4) UUID=<Add_UUID_here_without_""> /mount xfs defaults 0 0
  10. Now finally run mount command $ mount -a

Generally, if its new EBS volume you have to format it manually and then mount it, also manually. From docs:

After you attach an Amazon EBS volume to your instance, it is exposed as a block device. You can format the volume with any file system and then mount it.

The instruction for doing this in the link above.
