You did miss a step, which is to read /usr/src/UPDATING. The relevant sections follow: 19991210: The ata driver has become the primary ata/ide/atapi driver in the kernel. The wd driver is obsolete. You should upgrade your machine to the new ata driver. You will need to follow the directions for updating the devices in the 19991205 entry. You will need to update all occurances of wd to ad in your config files (/etc/rc.conf, /etc/fstab, etc). A compatibility device exists for wd for the time being, but once you have determined that ata is working for you, transition to the new ad devices. 19991205: Block devices are going away. You will need to update your /dev tree with a fresh copy of MAKEDEV for things to always work in the future. fsck is unable to cope with dirty file systems after this change, so it may work for you or it may not. See "To rebuild disk /dev entries" at the end of the file. *** All uses of block devices must be converted to char devices. *** Likely the only thing impacted is dumpdev in /etc/rc.conf To rebuild disk /dev entries ---------------------------- MAKEDEV should be copied from src/etc/MAKEDEV to /dev before starting the following: For N in the list of disks MAKEDEV N # eg ad0 for M in the list of slices MAKEDEV NsMa # eg ad0s1a -- Christopher Farley www.northernbrewer.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
