vgchange

vgchange is a command line tool in Linux used to manipulate the status of Volume Groups (VGs). It is primarily a part of the Logical Volume Manager (LVM) system, which provides advanced storage management capabilities. With vgchange, you can change the attributes of a VG, activate or deactivate it, and modify various properties associated with it.

One of the primary functionalities of vgchange is activating or deactivating VGs. Activation allows the VG to be accessed, and deactivation removes the access. You can activate or deactivate all VGs on your system or specify individual VGs.

vgchange also offers options to control the availability of individual Logical Volumes (LVs) within a VG. You can enable or disable specific LVs according to your requirements.

It allows you to modify the VG attributes, such as renaming the VG or changing its UUID (Universally Unique Identifier), which can be useful for identification or troubleshooting purposes.

Additionally, vgchange provides options to set the VG state to read-only or read/write, allowing you to control the write access to the VG.

Overall, vgchange is a versatile command line tool that enables you to manage various aspects of Volume Groups and Logical Volumes, providing flexibility and control over your storage management operations in Linux.
