What kind of workload do you have? I was no able to find a way to trigger znode_evict_error() call (this is what you're seeing). You could try changing '#if 1' to '#if 0' in zfs_znode.c:znode_evict_error(), but I don't think this code path was ever tested, because as I said, I was unable to trigger it. --=20 Pawel Jakub Dawidek http://www.wheelsystems.com pjd@FreeBSD.org http://www.FreeBSD.org FreeBSD committer Am I Evil?
