According to the documentation, with soft-updates enabled, the file system would be consistant, there would just be lost resources to be recovered which I am assuming can be safely done at a later time to avoid long periods of downtime during peek hours. "Soft updates control the ordering of filesystem updates such that the only inconsistencies in the on-disk representation are that free blocks and inodes may be claimed as "in use" in the on-disk bitmaps when they are really unused." So, would there be other issues if fsck wasn't ran right away after a system crash? Thanks, Scott
