Hello, I am running FreeBSD 7.0-RELEASE AMD64 on a dual dual-core xeon system, and I am having an odd problem with non-UFS filesystems. Any mounted filesystem that is not UFS will return a random, negative st_birthtime. Also, each time I stat the file I get a different value. The two mounted filesystems with this problem are ext2fs and smbfs. Here's my output from uname -a: [root@zeta /mnt/autoboxes/achristianson]# uname -a FreeBSD zeta.orases.com 7.0-RELEASE FreeBSD 7.0-RELEASE #0: Sun Feb 24 10:35:36 UTC 2008 root@driscoll.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC amd64 Here is some example ls -lU output: [root@zeta /mnt/autoboxes/achristianson]# ls -lU total 15750 drwxrwxrwx 1 www www 16384 Dec 26 1929 boonshaft -rwxrwxrwx 1 www www 15964062 Dec 26 1929 cachegrind.out.17937 drwxrwxrwx 1 www www 16384 Dec 26 1929 catgenie drwxrwxrwx 1 www www 16384 Dec 26 1929 cedarbrook drwxrwxrwx 1 www www 16384 Dec 26 1929 gams drwxrwxrwx 1 www www 16384 Dec 26 1929 gamsreview drwxrwxrwx 1 www www 16384 Dec 26 1929 gamsspec -rwxrwxrwx 1 www www 0 Dec 26 1929 jesus drwxrwxrwx 1 www www 16384 Dec 26 1929 lib24watch -rwxrwxrwx 1 www www 0 Dec 26 1929 newfile drwxrwxrwx 1 www www 16384 Dec 26 1929 test -rwxrwxrwx 1 www www 78 Dec 26 1929 testfile -rwxrwxrwx 1 www www 78 Dec 26 1929 testfile~ drwxrwxrwx 1 www www 16384 Dec 26 1929 usaf2008-impl drwxrwxrwx 1 www www 16384 Dec 26 1929 yff [root@zeta /mnt/autoboxes/achristianson]# ls -lU total 15750 drwxrwxrwx 1 www www 16384 Jan 14 1930 boonshaft -rwxrwxrwx 1 www www 15964062 Jan 14 1930 cachegrind.out.17937 drwxrwxrwx 1 www www 16384 Jan 14 1930 catgenie drwxrwxrwx 1 www www 16384 Jan 14 1930 cedarbrook drwxrwxrwx 1 www www 16384 Jan 14 1930 gams drwxrwxrwx 1 www www 16384 Jan 14 1930 gamsreview drwxrwxrwx 1 www www 16384 Jan 14 1930 gamsspec -rwxrwxrwx 1 www www 0 Jan 14 1930 jesus drwxrwxrwx 1 www www 16384 Jan 14 1930 lib24watch -rwxrwxrwx 1 www www 0 Jan 14 1930 newfile drwxrwxrwx 1 www www 16384 Jan 14 1930 test -rwxrwxrwx 1 www www 78 Jan 14 1930 testfile -rwxrwxrwx 1 www www 78 Jan 14 1930 testfile~ drwxrwxrwx 1 www www 16384 Jan 14 1930 usaf2008-impl drwxrwxrwx 1 www www 16384 Jan 14 1930 yff Here's some output from mount, so that you can see how things are mounted. Note that the problem occurs with or without the noatime option: [root@zeta /mnt/autoboxes/achristianson]# mount /dev/mfid0s1a on / (ufs, local, noatime) devfs on /dev (devfs, local) /dev/mfid0s1e on /tmp (ufs, local, noatime, soft-updates) /dev/mfid0s1f on /usr (ufs, local, noatime, soft-updates) /dev/mfid0s1d on /var (ufs, local, soft-updates) /dev/da0s1 on /mnt/usb (ext2fs, local, noatime) //SVN@CHEWBACCA/SANDBOX on /mnt/autoboxes/rpeters (smbfs, noatime) //SVN@GREEDO/SANDBOX on /mnt/autoboxes/koboyle (smbfs, noatime) //SVN@VADER/SANDBOX on /mnt/autoboxes/mloss (smbfs, noatime) //SVN@MACMINI/SANDBOX on /mnt/autoboxes/macmini (smbfs, noatime) //SVN@R2D2/SANDBOX on /mnt/autoboxes/achristianson (smbfs, noatime) //SVN@BOBAFETT/SANDBOX on /mnt/autoboxes/rgriffin (smbfs, noatime) //SVN@YODA/SANDBOX on /mnt/autoboxes/vpolyanov (smbfs, noatime) //SVN@DARTHMAUL/SANDBOX on /mnt/autoboxes/dmercer (smbfs, noatime) //ADMINISTRATOR@TITAN/BACKUP on /mnt/backup (smbfs, noatime) //SVN@JANGOFETT/SANDBOX on /mnt/autoboxes/mtomasello (smbfs, noatime) //SVN@GRIEVOUS/SANDBOX on /mnt/autoboxes/atalabac (smbfs, noatime) I do not think this is an SMBFS problem, because it happens exactly the same on /dev/da0s1 (ext2fs). Any ideas? Thanks in advance for any help!
