I try to find a suitable reading/howto for how to enable softupdates on UFS2 filesystems. As I could see, SU+J is enlisted to be enabled by default in 9.0-RELEASE. What is the status quo of that? I've several active systems running UFS2 on their system disks while data/home/mass storage is ZFS. Are their any issue with SU+J? well, the captitalized letters confused me first time, since the first newfs-option I hit was "-J", the option for enabling softupdate via GEOM gjournal. Is there any special preparation to bring up an existing filesystem securely into journaling? As I read the blogs and emails in the list, it should be as simple as booting into single user mode, enabling on all partitions in question (even / ?) via -j softupdate-journaling, runing a foreground fsck, reboot ... that's it? Or is there any other additional preparation like mentioned in gjournal (async mount)? Thanks for patience and repsonding, Oliver
