AWS Documentation

  • Using EBS Volumes
    • When you attach a volume to your instance, it is exposed as a block device
    • You can format the volume with a file system then mount it
      • Attach a volume using the AttachVolume API Call
    • If you restore a volume from a snapshot, the volume likely has a file system on it already
    • If you create a new file system on top of an existing file system, this operations overwrites your data
    • Use file -s command to get information about a device such as file system time
      • if the output simply shows data, there is no file system and you must create one
    • after you attach, you have to actually mount it with the mount command
    • EBS volumes must be in the same AZ as the EC2 instance
    • You can have up to 5,000 EBS volumes by default
    • You can have up to 10,000 snapshots by default
