The original thread was here: http://marc.info/?t=132502460000001&r=1&w=2 Ignore the part where it takes me a while to figure out fsck isn't softupdate-aware. There was further followup off-list with the associated SUJ developers with clearer test results, but no definitive resolution as of yet, as far as I know. I didn't get a chance to test the write cache disabling approach or do further testing before I had to turn off SUJ. Arnaud: Would you be able to record a few test cases with SUJfsck and then regular fsck, both using the -v flag (with output piped to some other fs)? Can you also see if: kern.cam.ada.write_cache=0 hw.ata.wc=0 while leaving SUJ enabled helps at all? > On 8 March 2012 11:07, David Thiel wrote: > > On Mon, Mar 05, 2012 at 05:12:16PM -0500, Arnaud Lacombe wrote: > >> I've been running a couple of system with 9.0-RELEASE since it is out. > >> All the system were installed through the standard installation > >> procedure.
