We have already (almost) finished with the logging part of the meta-data into a file and are currently working on getting the File system back up using the log file that we have generated.

The inspiration for this email was from a thread in -questions: "Re: fsck takes very long after crash/reset" Is anybody currently working on or does there exist a JFS for FreeBSD? I've read in the archives, the discussion about not really needing JFS because of the benefits of softupdates. As well as some talk about BSD / GPL license issues. Is there not a JFS for FreeBSD becuase, Softupdates do the job just fine and nobody has the time or interest to work on this? I'm not running FreeBSD 5.x. So I'm not able to take advantage of the background fsck. Can anybody comment on their success w/ the background fsck? If a JFS were to be ported and/or developed for FreeBSD what should it be based on? XFS, JFS, ReiserFS??? Who would be considered the "maintainer" for this type of work? --daxbert To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-fs" in the body of the message
