Unfortunately, I cannot appear to reproduce the problem any more. Re-upgrading to 0.40 now shows no problem, I've tried to explore the range of things I may have done, but with no luck. I had to trash my journals in order to downgrade, so there is some amount of state that was lost which may be related to my inability to reproduce now? For what it is worth, I believe the problem may have been caused by something the 0.40 versions were sending. As I was downgrading back to 0.39, the downgraded 0.39 version kept dying with the same error as long as one of the 0.40 versions was still up. I did not know of the ms debugging when I was first investigating, but looking through my old data, I have a trace with OSD debug set to 20 of the 0.39 version dying of the fault: http://joshp.no-ip.com:8080/20120114-osd-family-error.log.bz2 -Josh -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
