hej, I've never played with gjournal before and would like to try it to get protection of the root-fs, var and tmp. I'm wondering if someone can answer these simple questions: 1) As I understand, gjournal does not need to run on a filesystem but is also able to journal a whole slice. What are the pro's and con's for running gjournal on a whole slice or per filesystem? 1a) if journaling per filesystem, is gjournal able to use just one journaling area for more than one filesystem? 2) How much space is required for journaling? I'm having space to get the journal into it's own slice or at least a bsd label. The fsys layout is quite simple: slice 1 (10g) / 2G /tmp 2G /var 4G slice 2 (8g) can be used for spare space and for gjournal but I'm unsure how much space to give gjournal. Thanks! Volker
