Since the gjournal is block level journaling, not file
system level journaling, can one journal be used to
cover two or more partitions?
Example:
gjournal label -c ad0s4e ad0s4d
gjournal label -c ad0s4f ad0s4d
gjournal label -c ad0s4g ad0s4d
newfs -J /dev/ad0s4e.journal
newfs -J /dev/ad0s4f.journal
newfs -J /dev/ad0s4g.journal
Kind Regards
