Public bug reported: 1) The release of Ubuntu you are using, via 'lsb_release -rd'
Description: Ubuntu Xenial Xerus (development b ranch) Release: 16.04 2) The version of the package you are using, via 'apt-cache policy pkgname' systemd: Installed: 229-3ubuntu1 Candidate: 229-3ubuntu1 3) What you expected to happen I am testing our E-Series Netapp storage array and the ability of the server to failover IO to the secondary path. 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.
