From: Maxim Konovalov To: bug-followup@freebsd.org Cc: Subject: bin/65223 Date: Mon, 6 Sep 2004 10:17:02 +0400 (MSD) Add some info about the root of the problem from Kirk McKusick: http://freebsd.rambler.ru/bsdmail/freebsd-current_2003/msg04802.html : Executive summary: you need to run `fsck -f -p' whenever you switch : to or from a 4.X (stable) and a 5.X (current) kernel. The reason : is that the UFS1 superblock summary information is maintained in : different parts of the superblock on these two systems. Neither : system maintains the summary information used by the other. There : is no risk of trashing your filesystem if you fail to run the fsck, : but the information reported by `df' will be wrong until you run : the fsck. -- Maxim Konovalov
