SSD drives not accessible in EC2 ubuntu Instances

Question

In the following EC2 instance types which have SSD drives

• r3.2xlarge
• r3.4xlarge
• i2.xlarge

When I login through SSH, I am unable to see the SSD drives. I was trying "df -h".

I have tried

• reboot, but that did not help.
• tried to terminate and create a new instance that also does not help. Suggesting that its not one-off issue.

Answer 1

I found one solution by trying the steps suggested for adding EBS volumes to Ubuntu instnaces

Below are my steps:

• sudo mkfs.ext4 /dev/xvdb
• sudo mkdir -m 000 /mnt # isnt required if /mnt exists.
• echo "/dev/xvdb /mnt auto noatime 0 0" | sudo tee -a /etc/fstab
• sudo mount /mnt
