Format, Extend/Reduce and Create Volume Groups / Logical Volumes in Linux

Recently I had to set up some linux volumes and partitions in a production environment. I have compiled some points that I find relevant.

In this post I will show you how to do the following configurations in Linux Operating Systems:

• Add a new Physical Volume and Create Partition;
• Create new Volume Group and Logical Volume with one or more disks;
• Extend Volume Group with new Logical Volume;
• Extend Volume Group and the Logical Volume;
• Reduce a Logical Volume;
• Mount/Umount NFS Volumes

3PAR Procedures - Replace Disk, Remove Disk & Change Disk Position - Rebalance

In the first Post of the year I will show you three procedures regarding disk failure, remove a disk from the CPG and rebalance disk position in a 3PAR array.

• Replace a failed disk in 3PAR
• Objective: Remove failed disk and replace with a new one
• Remove disks from the CPG and rebalance the data
• Objective: Remove a disk from the 3PAR. The disk will be in New state and you can use it in another 3PAR
• Change disk position in 3PAR so you can rebalance data in the array
• Objective: Maximize performance of your array when you upgrade the 3PAR with new cages or disks

Let's see how to do this three procedures.
