vCSA-Extending LogicalVolume

When using the vCenter Server Appliance it’s possible that some volumes (most likely those involving logs) may start to get full, generating alarms. This blog provides steps to increase the disk space of a specific VMDK for the vCenter Server Appliance 6.7. With the introduction of Logical Volume Management (LVM) in vSphere 6.0 and continued support with vSphere 6.5 and 6.7, the vCenter Server disks can be dynamically increased.

Note: – Resizing the root partition (VMDK1 in the table below) is not supported.
