![]() Initialize devices to use with the LVMIn order to do this, we need to use the pvcreate command.The EBS volumes are given the following device names: ‘/dev/sdf’, ‘/dev/sdg’ and ‘/dev/sdh’. Attach EBS volumes to your EC2 instanceIn this case, we are attaching three 10GB SSD EBS volumes.LVMs provide the ability to dynamically expand and shrink virtual partitions and make additions to physical volumes on the fly for existing LVMs. You can have multiple virtual partitions on a physical volume or a single virtual partition over multiple physical volumes. LVMs create an abstraction layer on top of underlying disk layouts and allows sysadmins to create virtual partitions over physical volumes. In this post, we’ll take a deeper look at dynamic disk arrays (i.e., LVM). With multiple EBS volumes, network performance is increased between EC2 instances and EBS volumes. To fix these issues, the organization decides to leverage Logical Volume Managers (LVMs), which provide the option to easily increase the size of their volume by adding more EBS volumes. On top of that, there are network performance bottlenecks between EC2 instances and the EBS volume that impact system performance on the whole. However, this causes a problem for the organization because shutting down the database server results in lost business. But, every time they increase it, a maintenance window has to be scheduled where the database server is shut down, an EBS snapshot of the data volume is created, and a newer, bigger volume is created and attached to the instance. In terms of storage, the organization has a 1TB EBS volume, which they can increase to 16TB. ![]() As the company grows, the size of its database also grows at a rate of 10GB per day. Picture the following scenario: an organization uses EC2 instances for its database where data is stored in EBS volumes.
