Reduce LVM

-

Reduce an LVM: consider the lvm size is 15G and want it to reduce to 10G

unmount the filesystem

#umount /mnt/pathtreduce

#e2fsck -ff /dev/vgname/lvname

#resize2fs /dev/vgname/lvname 10G (10G is the final size to which you want to reduce)

#lvreduce -l -5G /dev/vgname/lvname

#mount /dev/vgname/lvname /mnt/pathtreduce

Amazon Web Services (AWS) Auto Scaling is a service that allows you to automatically adjust the number of Amazon EC2 instances (virtual servers) in your AWS environment to handle changes in workload, traffic, or resource utilization. It helps you ensure that you have the right number of instances running at any given time to maintain application availability and performance while optimizing costs. Here's a breakdown of key concepts and how AWS Auto Scaling works: 1. Auto Scaling Groups (ASGs):   An Auto Scaling Group is a fundamental component of AWS Auto Scaling. It defines a collection of Amazon EC2 instances that share similar characteristics and are treated as a logical grouping for scaling purposes. Instances within an ASG are launched from the same Amazon Machine Image (AMI) and have the same configuration settings. 2. Scaling Policies: AWS Auto Scaling allows you to define scaling policies that specify when and how the Auto Scaling Group should scale. There are two prim...

Introduction Jenkins, the popular open-source automation server, offers a powerful feature known as pipelines to streamline and automate your software development processes. Jenkins pipelines enable you to define, automate, and manage your entire software delivery workflow as code. In this blog post, we'll dive into the world of Jenkins pipelines, discussing what they are, their benefits, and how to create them effectively. What are Jenkins Pipelines? Jenkins pipelines are a set of instructions defined in code that specify how Jenkins should build, test, and deploy your software. They are designed to replace the traditional, point-and-click job configuration in Jenkins with a more structured and flexible approach. Pipelines can be defined using either Declarative or Scripted syntax, giving you the flexibility to choose the best fit for your project. Benefits of Jenkins Pipelines 1. Code as Configuration: Jenkins pipelines are defined as code, allowing you to version control your bu...
