I have a drive (/dev/ad2s1d) mounted to /backup that I want to be read only until the backup scripts run and then it will be read/write. If I set /etc/fstab to: /dev/ad2s1d /backup ufs ro 0 0 to mount it read only most of the time then do: umount /backup mount -o rw /backup the system crashes, it just reboots about 10 seconds into writing data. The system is perfectly stable with it mounted read/write. Also, dmesg.boot has completely disappeared from the system, and touch /var/log/dmesg.boot it does not get populated. # uname -a FreeBSD arthur.silvertree.org 7.2-RELEASE-p3 FreeBSD 7.2-RELEASE-p3 #1: Fri Aug 14 13:27:47 PDT 2009 root@arthur.silvertree.org:/usr/ obj/usr/src/sys/ARTHUR i386 Any suggestions on the remounting drive and dmesg.boot? Thanks! Scott P.S. It's good to be off of FreeBSD 4.11 :)
