So do I. Is there a good way to debug this, i. e. more systematic than just trying to trash the FS and see if fsck can recover? > That said, I rarely, if ever, see softupdate > problems on my SCSI development systems, but that might just be > coincidence. I posted about softupdate problems on a SCSI system with DISABLED WRITE CACHE, on a somewhat flakey Micropolis drive that froze and caused massive ffs+softupdates corruption in February 2004 (on FreeBSD 4 though), see for the archived post, including logs. So that makes two for me and some more for Dan. -- Matthias Andree
