http://bugzilla.suse.com/show_bug.cgi?id=1056408 Bug ID: 1056408 Summary: dm-mpath path remove/add events are received out of order Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: Other OS: Other Status: NEW Severity: Minor Priority: P5 - None Component: Kernel Assignee: kernel-maintainers@forge.provo.novell.com Reporter: martin.wilck@suse.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- Created attachment 738867 --> http://bugzilla.suse.com/attachment.cgi?id=738867&action=edit Full journalctl output of the test run I'm not sure if this is really a bug. Currently just documenting it here for further reference. The following is an excerpt of udev monitor output captured while removing and re-adding paths to a multipath map. All paths are removed using the "delete" attribute of the SCSI devices in sysfs until no paths are left, and re-added using "scan" on the scsi host later. It would be expected that NR_VALID_PATHS decreases monotonically to 0 while this happens, and increases again to the full path count (6). The logs show that this is not the case:
