Troubleshoot a Broken LVM Configuration

About this Hands-on Lab

LVM archives take a backup of the file system every time a major action is taken against the file system itself (such as a change in volume group size). These backups can then be used to restore an LVM volume to a functioning state should something go wrong with the disk. In this lab, you will use one of these backups to recover an LVM configuration after the file system fails to mount. _This lab is not approved or sponsored by Red Hat._

Learning Objectives

Successfully complete this lab by achieving the following learning objectives:

Attempt to Mount the File System

View the file system table, and then use the mount command to attempt to mount the appropriate file system.

Recover the File System

Use the existing archives of the LVM volume to restore to a previous point in time.

Mount the File System

Mount the file system again and confirm you can now do so successfully.

Additional Resources

The /data file system endpoint is throwing an error when you attempt to mount it. You know the file system uses LVM, so you can use LVM tools to troubleshoot. Confirm what is causing the issue, and then resolve it.

Note: You will need to become the root user to perform the actions in this hands-on lab.
