From: Rex Luo X-Mailer: TWIG Sender: owner-freebsd-fs@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.org Dear, Sorry to not survey thoroughly, and maybe someone can give me some information quickly. Since Filesystem logging can be 3 common forms:(Solaris interinals Core Kernel Architecture Jim Mauro. Richard McDougall) 1. Metadata logging -- logs only file system structure changes 2. File and metadata loggging -- Logs all changes to the filesystem 3. Log-structured file system -- The entire file system is implemented as a log I remember I have seem on mailinglist that FFS with softupdate has similar function as journal filesystem. What kind of journal filesystem it can be? or I am totally wrong.
