The first might have a legitimate uncoordinated write, but the last two are not regularly touched by anything but the repair process, and this identical failure has occurred for the past 4 days. I'd appreciate it if this is fixed before my leases expire. :-) {{{ ERROR: UncoordinatedWriteError() ""[Failure instance: Traceback (failure with no frames): : "" ERROR: AssertionError() ""[Failure instance: Traceback: : "" /Volumes/Opp/External/Projects/tahoe/src/allmydata/mutable/filenode.py:563:upload /Volumes/Opp/External/Projects/tahoe/src/allmydata/mutable/filenode.py:661:_do_serialized /Volumes/Opp/External/Projects/tahoe/support/lib/python2.6/site-packages/Twisted-11.1.0-py2.6-macosx-10.6-x86_64.egg/twisted/internet/defer.py:298:addCallback /Volumes/Opp/External/Projects/tahoe/support/lib/python2.6/site-packages/Twisted-11.1.0-py2.6-macosx-10.6-x86_64.egg/twisted/internet/defer.py:287:addCallbacks --- --- /Volumes/Opp/External/Projects/tahoe/support/lib/python2.6/site-packages/Twisted-11.1.0-py2.6-macosx-10.6-x86_64.egg/twisted/internet/defer.py:545:_runCallbacks /Volumes/Opp/External/Projects/tahoe/src/allmydata/mutable/filenode.py:661: /Volumes/Opp/External/Projects/tahoe/src/allmydata/mutable/filenode.py:689:_upload /Volumes/Opp/External/Projects/tahoe/src/allmydata/mutable/publish.py:402:publish ERROR: UncoordinatedWriteError() ""[Failure instance: Traceback (failure with no frames): : "" ERROR: UncoordinatedWriteError() ""[Failure instance: Traceback (failure with no frames): : "" }}} Before these failures, here is a typical example of normal results. (The indentation is added by my script.) I had understood the post-repair unhealthiness to be due to disagreement between the ""healthy file"" and ""repair (successful re-upload)"", a to-be-fixed bug. {{{ done: 3 objects checked pre-repair: 3 healthy, 0 unhealthy 0 repairs attempted, 0 successful, 0 failed post-repair: 3 healthy, 0 unhealthy repair successful done: 1 objects checked pre-repair: 0 healthy, 1 unhealthy 1 repairs attempted, 1 successful, 0 failed post-repair: 0 healthy, 1 unhealthy repair successful done: 5 objects checked pre-repair: 4 healthy, 1 unhealthy 1 repairs attempted, 1 successful, 0 failed post-repair: 4 healthy, 1 unhealthy repair successful done: 5 objects checked pre-repair: 4 healthy, 1 unhealthy 1 repairs attempted, 1 successful, 0 failed post-repair: 4 healthy, 1 unhealthy }}}" defect closed critical 1.9.2 code 1.9.0 fixed tahoe-check verify ucwe regression review-needed kpreid killyourtv@…
