Agreed. Added to http://wiki.freebsd.org/DocsFor9x . > As I could see, SU+J is enlisted to be enabled by default in 9.0-RELEASE. Yes, it is on by default in bsdinstall (and I think in newfs?

I haven't been tracking what's been going on, but several bugfixes have gone in in the last couple of months post-SUJ. There might be some bugs in the work, but most standard operations work out of the box for me at least. ... > =A0 I hit was "-J", the option for enabling softupdate via GEOM gjournal.

If all goes well, that was the entire process IIRC. > Or is there any other additional preparation like mentioned in gjournal > =A0 (async mount)? ENOCLUE (because I'm not aware of that with gjournal -- the last time I tried setting it up things didn't work too well for me) :). > =A0 Thanks for patience and repsonding, Sure :)! -Garrett
