Hi Hideo,

The --sos-mode option is intended for RHEL integration, so it is only
guaranteed to work with the combination of pacemaker and sosreport
packages delivered with a particular version of RHEL (and its derivatives).

That allows us to make assumptions about what sosreport features are
available. It might be better to detect those features, but we haven't
seen enough usage of sosreport + pacemaker outside RHEL to make that
worth the effort.

In this case, the version of sosreport that will be in RHEL 7.4 will
collect pacemaker.log and corosync.log on its own, so the crm_report in
pacemaker 1.1.16 doesn't need to collect the logs itself.

It might work if you build the latest sosreport:
