Data protection operation fails in a non-multipath environment in RHEL 7 and later


When you perform any data protection operations in a non-multipath environment in RHEL 7 and later, the operations fail with an error message.

Error message

  2. Change the configuration value of use_lvmetad from 1 to 0 in the lvm.conf file.

    The file is located at: /etc/lvm/ directory.

  3. Restart the LVM metadata service.
