Core was generated by `pvscan'.
Program terminated with signal 11, Segmentation fault.

I believe it's been fixed by this upstream commit: https://www.redhat.com/archives/lvm-devel/2016-September/msg00103.html in version 2.02.167 Marking verified (SanityOnly) as this was never reliably reproducible. I blanked out many PVs from one node in the cluster and scanned from others w/o any issues. 3.10.0-657.el7.x86_64 lvm2-2.02.171-1.el7 BUILT: Wed May 3 07:05:13 CDT 2017 lvm2-libs-2.02.171-1.el7 BUILT: Wed May 3 07:05:13 CDT 2017 lvm2-cluster-2.02.171-1.el7 BUILT: Wed May 3 07:05:13 CDT 2017 device-mapper-1.02.140-1.el7 BUILT: Wed May 3 07:05:13 CDT 2017 device-mapper-libs-1.02.140-1.el7 BUILT: Wed May 3 07:05:13 CDT 2017 device-mapper-event-1.02.140-1.el7 BUILT: Wed May 3 07:05:13 CDT 2017 device-mapper-event-libs-1.02.140-1.el7 BUILT: Wed May 3 07:05:13 CDT 2017 device-mapper-persistent-data-0.7.0-0.1.rc6.el7 BUILT: Mon Mar 27 10:15:46 CDT 2017 cmirror-2.02.171-1.el7 BUILT: Wed May 3 07:05:13 CDT 2017 Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
