Thanks, Garrett. Ran fsck -y /usr * FILE SYSTEM MARKED CLEAN * * FILE SYSTEM WAS MODIFIED * Upon reboot, all is well EXCEPT for the following 2 warnings: --- Mounting local file systems: WARNING: /var was not properly dismounted WARNING: /sambavol was not properly dismounted --- Both /var and /sambavol are mounted (ufs, local, soft-updates). Rebooted again, and did not get these warnings. Thanks!

Re: UNEXPECTED SOFT UPDATE INCONSISTENCY
Yes, it's a hardware switch and a very bad design. It's flush with the surface of the faceplate and is right next to the CD-ROM button. Also sensitive to the lightest touch. Replacement would require buying a new case (not in budget). Think I'll make a clear plexi failsafe cover.

That was your second error. As I learned it: On anything other than a clean shutdown, you will need to fsck everything that was mounted at the time of the crash.

Re: Unexpected soft update inconsistency
Peter Schuller wrote: Hello, What's the deal with soft updates and guaranteed consistency? Every time journaling is brought up by someone, he/she is promptly told about how soft updates does the job at least as well. I never had a problem with this based on what I have read about soft updates. However: I *very* quickly ran into a case where I got an unexpected soft update inconsistency after crashing the machine by doing something naughty with Vinum while there was disk activity (note: the filesystem which exhibited the problem was not on a vinum volume). So my question is: Do soft updates, or do they not, algorithmically guarantee filesystem meta-data consistency in the event of a crash? The design goal for Soft Updates, apart from the performance gain, was to keep the disk image in a recoverable state at all times and to limit data loss to the last couple of seconds. This does not mean, however, that it guarantees that after a crash fsck(8) will never ask any questions. Normally, the right thing to do is to answer with 'yes' when it offers to remove the file, since that file can be expected to be incomplete. This way you are kind of turning back the clock by a couple of seconds, from the file system's point of view, until it gets into the time range again where all files were still consistent (payload and meta data).

If you have a power failure or similar unclean shutdown, then SU guarantees consistency. If there is a kernel panic or hardware failure, all bets are off, because there is no way to be sure that the kernel was writing the correct bits to the hardware prior to the crash, or that the hardware was writing the correct bits to disk.

Re: Unexpected Soft Update Inconsistency / Cannot Read: Blk
Unfortunately the answer presented itself very soon after posting the message. I pulled the hard drive out of the box, and tried to format it in a Windows machine. It occurred to me that the drive had not been formated and therefore had not had data written to all parts of the disk. Half way through the format I got an 'Unsafe removal of device' message, and upon reboot the drive was TOTALLY dead. It would be nice if FreeBSD had a SMARTY utility - it would have allowed me to possibly detect this failure. I've been told that work is underway to write one and it might be ready for 5.0.

Well to pass on something I do with every new disk I buy. If I do not have it already I get the diagnostics for it from the disk manafacturers website, which they all have for free. I then run all the tests on the disk and format it. These are almost always standalone boot images that fit on a DOS floppy. Later on it is always handy if you suspect disk problems -- then you can run the non-destructive drive tests as well. I do as many other kinds of test as possible on new hardware before I start using the machine (usually one I am buiding) -- on the fairly well-known principle that anything electronic or electro-mechanical usually fails early in it's life if it is borderline.
