Previous versions of multipath stored path binding data directly in either /etc or the /var/lib directories. Recent versions have moved this to the subdirectory /etc/multipath to allow more consistent SELinux labelling of multipath files.
Previous versions of sos did not capture the files now stored in this location.
The devicemapper module has been extended to also include the /etc/multipath directory contents.
Full bindings data is now captured on hosts using the new directory layout.
