How Do I Fix Error "Failed to obtain information about disk X" When I Start the Agent on a Linux Source Server?

Symptom

When you started the Agent on a Linux source server, you received message "Failed to obtain information about disk %s. Cause: unknown physical volume!"

Possible Causes

The source server uses LVM and there are unknown physical volumes on the server. The Agent cannot collect the information about these volumes.

You can run the pvs command on the source server to check the details about its physical volumes.

Solutions

  1. Contact technical support of the source platform to restore the source server.
  2. After the source server is restored, run the pvs command to check if there are still any unknown physical volumes on the server.

    If there are no unknown physical volumes, perform the migration again.
