I believe this is problematic. Yes, I do via dump -L. I don't otherwise (no mksnap_ffs). I had some thoughts about that. But... I remember discussing this on geom list and I think pjd said that this should work and also it worked for me flawlessly except for that one moment. BTW, those filesystems are mounted like the following: ufs, asynchronous, local, noatime, gjournal This is to say that I do not mix gjournal and softupdates, which is also possible (at least not prohibited). -- Andriy Gapon
