A user has attached an EBS volume to a running Linux instance as a “/dev/sdf” device. The user is unable to see the
attached device when he runs the command “df -h”. What is the possible reason for this?
The volume is not in the same AZ of the instance
The volume is not formatted
The volume is not attached as a root device
The volume is not mounted
When a user creates an EBS volume and attaches it as a device, it is required to mount the device. If the device/volume
is not mounted it will not be available in the listing.
