I haven't looked at the dump yet but here's my initial thoughts (also posted on the bug report on github):
It's possible that this is the fallout from hitting bug 3603, which was fixed a few years ago. Have you run this pool without the following fix? A workaround for this problem would be to add code to bpobj_enqueue_subobj to ignore the subsubobjs if it does not exist (i.e. dmu_object_info() returns ENOENT, as it has here). This would leak some space (perhaps a very small amount of space) but allow you to recover all the blocks that can be found. commit d04756377ddd1cf28ebcf652541094e17b03c889 Author: Matthew Ahrens <[email protected]> Date: Mon Mar 4 12:27:52 2013 -0800 3603 panic from bpobj_enqueue_subobj() On Mon, Feb 22, 2016 at 3:07 AM, Adrian Ortmann <[email protected]> wrote: > Hi, > > got a smartos server that crashes every hour since Jan 15 21:08.
