I have run for a bit now and have not seen anymore erroneous unmounts. I'll call this one fixed and verified.

I pull a cable and allow DM-MP to fail the path and route IO down the other path. I then replug the cable and repeat for the other path. I expect that the failover to occur and for the mount points to stay mounted through the operation. 4) What happened instead I see in the system log that during the test systemd tries to perform an unmount operation on the mountpoint of the dm-device(s) that have lost an underlying path. The unmount fails, I assume because there is active IO at the time. However it should not be attempted in the first place. I believe this is related to the bug that we discovered in RHEL and SLES that can be seen in this redhat commit: https://github.com/lnykryn/systemd- rhel/commit/d77ced281c6d1f47b5dfc3abff6817d8f5756af9 Our testing of RHEL seems to indicate that this patch resolved our problem.
