And what happens then? Are all ZFS vnodes then gone *or* is the write which couldn't be done silently discarded? The "nice" thing about the panic is that the application is stopped in its track and knows that it needs to start recovering. If you kill the ZFS daemon and restart it, data *is* lost but will the application find out. It seems that you may just have lost one of the nice properties of ZFS. Not that I think the system should panic; the file in question should be marked bad and further I/O should fail with EIO as should fsync().
