First, unless you've got a good reason - and wanting functionality that's not in -STABLE is NOT a good reason - you shouldn't be running -CURRENT. See section 20.2.1.2 of the handbook for good reasons for the two good reasons for running -CURRENT. The best course of action would be to ask on the -current mail list to see if anyone there is interested in looking into this, as there's a good chance you've stumbled on a bug in the experimental file system snapshot code that's being used in -CURRENT. If you aren't on the -current mail list, you should be - that's even more critical than being on the -stable list if you are tracking -stable, and the latter is pretty much a requirement. Finally, if you just want to fix this to get the system up before going back to -stable, use "fsck_ffs -b 32 /dev/ad0s2e", as fsck has been replaced by something that deals with snapshots and background fscks, and the old fsck is now fsck_ffs. I'd also ask on the -current mail list for advice about taking a file system that may have had snapshots enabled on it back to a -stable kernel. <mike -- Mike Meyer <mwm@mired.org> http://www.mired.org/home/mwm/ Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information.
