Hi all, I have read several articles on the issue and spoken to a few people regarding this issue and when ever I mention a journaling file system to FreeBSD people I automatically get pointed to Soft Updates as being an equivalent. As far as I am aware this is not case at all. The whole point of a journaling file system on systems such as Linux/NT/Solaris etc. is not to increase performance but rather to avoid an 'fsck' when the server gets shutdown "uncleanly". This is because fsck can take several hours to run on a very large filesystem. FreeBSD's ffs curently cannot do this (avoid an fsck) with or without soft updates. Soft updates of FreeBSD is merely there to increase performance. I may have this all wrong (someone please correct me if I have) but soft updates is NOT an equivalent to a journaling file system. --------------------------------------------------------------------- It is automatic log-in and notification.
