I was wondering what the current state of opinion was for using soft-updates on top of a geli provider. From what I've read, disk write caching reduces the effectiveness of soft-updates. I was curious if geli with authentication would obsolete soft-updates or not. I may be mis-understanding soft-updates. >> P.S. Anyone running ZFS on multiple geli providers? > > as above. Does that mean you are/aren't or have/haven't run ZFS on top of, say, 3 geli encrypted disks? I'm curious as to whether there are many people who have tried it, and use it. Vinny
