How can it come about? Is this from replacing a brick days ago? Can I

did not complete, failing fop with
EBADF (old-subvolume:gv-nova-3 new-subvolume:gv-nova-4)
It's critical because it causes a segfault every time. :(
Joe,
This is fd migration code. When a brick layout changes (graph
change) the file needs to be re-opened in the new graph. This re-open
seemed to have failed. It leads to crash probably because extra unref
in failure code path. Could you add brick/mount logs to the bug
https://bugzilla.redhat.com/show_bug.cgi?id=1123289. What is the
configuration of the volume?
I checked the code, I don't see any extra unrefs as of now. Please
provide the details I asked for in the bug.
CC Raghavendra G, Raghavendra Bhat who know this code path a bit more.
