My FreeBSD 5.2.1 server had a 4.5 GB HDD. I decided to upgrade it with a larger drive. I installed a new drive on the second IDE channel which made it ad2, of course, my original drive was ad0. I created a partition, boot loader and matching slices on the new drive. Then I copied the old drive to the new drive using tar. Once finished, I removed the original drive and installed the new one on the primary channel. When I booted up everything appeared normal, but when the system starts to mount "/" it gives no error or warning and just drops to a "Manual mount root specification" prompt. If I type "ufs:ad0s1a" it boots up and everything is perfect. This is the same slice "/" was on the old drive as well. I have tried the following with no success: Checked /etc/fstab boot0cfg -v -B ad0 bsdlabel -B ad0s1 tried booting from a cd, going into post install config, fdisk, and set the partition as bootable, it already was. Since upgrading the hard disk, I have upgraded the system to 5.5 and then to 6.2. This system has been working great for over a week now, just have this boot problem. -------------- Here is my fstab: /dev/ad0s1b none swap sw 0 0 /dev/ad0s1a / ufs rw 1 1 -------------- Output from bsdlabel # bsdlabel ad0s1 # /dev/ad0s1: 8 partitions: # size offset fstype [fsize bsize bps/cpg] a: 585018626 1048576 4.2BSD 2048 16384 28552 b: 1048576 0 swap c: 586067202 0 unused 0 0 # "raw" part, don't edit -------------- Output from boot0cfg # boot0cfg -v ad0 # flag start chs type end chs offset size 1 0x80 0: 1: 1 0xa5 1023:254:63 63 586067202 version=1.0 drive=0x80 mask=0xf ticks=182 options=nopacket,update,nosetdrv default_selection=F1 (Slice 1) Thanks, David
