Is it safe to do so on existing filesystem (if I'm using 2nd partition for journal)? i.e.: $ grep ad0s1f /etc/fstab /dev/ad0s1f /usr ufs rw,noatime 2 2 $ grep ad0s1b /etc/fstab #/dev/ad0s1b none swap sw 0 0 # gjournal label ad0s1f ad0s1b # gjournal load # fsck -y /dev/ad0s1f.journal # sed -i -e 's|ad0s1f|ad0s1f.journal|' /etc/fstab # sed -i -e 's|noatime|noatime,async,gjournal|' /etc/fstab # mount /usr -- NEVE-RIPE, will build world for food Ukrainian FreeBSD User Group http://uafug.org.ua/
