The journal consumes some drive space but for any filesystem over 20-30 GB it won't limit your storage capacity very much. I do not have any external drives formatted with FFS, and I would be interested to know myself if it is at all possible to use gjournal(8) with an external usb drive. Someone else on the list must know the answer to that question. You should read the man page for gjournal(8) and note the part about disabling soft-updates and using the async mount(8) option. There is a short intro to the topic in the handbook. http://www.freebsd.org/doc/en/books/handbook/geom-gjournal.html Cary
