thanks Michael, but in all documentation about journaling, tunefs is used
as below: "tunefs -J enable ad3s1X.journal". ad3s1X.journal is created by
gjournal command: "gjournal label ad3s1a ad3s1g" that assign ad3s1g as
journal provider for ad3s1a and create ad3s1a.journal which contains ad3s1a
as data provider and ad3s1g as journal provider.

my problem is, i can not run gjournal command for root partition in fixit
mode nor single user mode. you mean, i should just use tunefs command on
ad3s1X (root partition)? if yes, then where journal provider for root
partition is located? in root partition?
