Yes, this is what I have done for my 9.0 servers. Unfortunately you=20 need to be in single user mode if you need to change /'s setting. This = is because you cannot change this option while a file system is mounted=20 read+write. Rebooting into single user mode is the easiest way to do=20 this, as it leaves you with / mounted read only and everything else=20 dismounted for you. Then I ran: tunefs -j disable /<mountpoint> For each volume that journaling was enabled for. As a side note remove the .sujournal file in the base of each volume=20 afterwards as it just takes up space. After doing this I have been using dump(8) nightly via cron(8) for about = a week now under 9.0 without issue.
