https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D207247 Bug ID: 207247 Summary: GEOM multip Product: Base System Version: 10.2-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: crest@bultmann.eu CC: freebsd-amd64@FreeBSD.org CC: freebsd-amd64@FreeBSD.org GEOM multipath cycles through all paths to a device without remembering previous path failures or differentiating between path and medium errors as mentioned in #178473. I had a device fail during a planned clean power cycle with this result: GEOM_MULTIPATH: Error 5, da22 in jbod2data35 marked FAIL GEOM_MULTIPATH: all paths in jbod2data35 were marked FAIL, restore da68 GEOM_MULTIPATH: da68 is now active path in jbod2data35 (da68:mps1:0:99:0): READ(10).
