I want to disable write cache on the disk drives in our J4200 JBODs so that fsync() actually writes to disk, not just to the cache on the drive.
 
I did this using 'format -e', but it displays a warning about the drive being part of a zpool and also it says that the change is not permanent.
 
Is 'format -e' the right way to do this with ZFS?  Is there no way to make it permanent?
