If not, you can use newfs -j or tunefs -j to enable it. "When any other means fail, read the manual" heh :-) I am still a bit confused, even after reading [1], because there is no explanation of difference between GJournal and SU / SU+J (which was introduced in FreeBSD 9.0). I understand GJournal works below filesystem level and I dont need to use fsck. SU/SU+J is part of the UDF/UDF2 filesystem. I should not use SU and GJournal at the same time. What are the advantages of SU/US+J? What is the advantage of SU+J over SU? Should I use Gjournal or SU/SU+J? Any hints welcome! :-) If I have already created UFS2 with -J, I understand I can switch it off, can I then simply turn of UFS+J (-j) with no data loss on existing filesystem? Which solution is better for drives >1TB when I dont want to wait an hour for fsck?
