My guess is that your boot loader was installed or configured for an earlier version of FreeBSD, where /kernel used to be the place to go ... and maybe you just don't reboot all the much, or something got knocked loose in the times before the power outage. At any rate ... check the handbook for how to replace your MBR (typically needed after installing Windows) which might do the trick. Otherwise, it is maybe missing some crucial hint from a file that got clobbered from the /boot or /kernel directories or something? I'd like to think that that will get fixed when you upgrade to 5.4. :) (If you really want to know the answer, find a good resource on FreeBSD bootstrap process. There have been changes these past few years, so I'm pretty sure people have been writing about this ...)

I am puzzled by the fact that I can get a directory list, but the boot loader thinks the format is wrong. Also it seems to be looking in /kernel and not /boot/kernel/. To work around the Disk 2 problem, I downloaded FreeSBIE and ran fsck from that. / reports as clean, but the box still does not boot. /usr and /home report HUGE numbers of uncorrectable errors and bad blocks. Tonight I am going to run SpinRite on the disk to see if the power outage really damaged the disk. (If it did, this will be the first time since the MFM/RLL disk days!) I will report the result of that test. Right now, I am thinking a power loss shutdown of 5.3 makes a system unrecoverable, but more of these tests are required before reaching that conclusion. Actually - I'd have to contradict that. I've been running 5.3 on my fileserver on the home network, and during the last few nasty storms my UPS didn't survive, and died off 5 times in a week (yes, I replaced it), and each time FreeBSD came back up like a champ - no lost files (that I could find.. .yet) or anything! knocks on wood. Thanks, stheg Hello, Thanks for that information. I have reached that conclusion myself based on two more tests. Both those times the system came up fine. The time the system did break is very strange. I ran a disk surface diagnostic and the platters are fine. The strange thing is I can mount the drive in another 5.3 system and read the files, but I cannot boot up the drive because I get an error that says Invalid Format. Clearly something is broken in the boot process such that the process cannot recognize the filesystem type eventhough the data (except for some files in /var and /home) are intact. This seems to be similar to the problem that cell posted about that prompted my test in the first place. Odd that such a specific thing should break. Oh, well. Not the oddest thing I've seen an OS do by a longshot. Best regards, stheg __ Do You Yahoo!? Tired of spam? Yahoo!

cannot boot 5.3 after power failure - major bug?
Hello, While testing 5.3, I deliberately cut power to the box and powered up. Much to my surprise, I receive the following error: error 16 lba invalid format FreeBSD/i386 boot Default: 0:ad(0,a)/kernel boot: No /kernel FreeBSD/i386 boot Default: 0:ad(0,a)/kernel boot: The disk is/was formatted as UFS2 (dangerously dedicated) with softupdates. If I enter a command, nothing happens: FreeBSD/i386 boot Default: 0:ad(0,a)/kernel boot:fsck -y FreeBSD/i386 boot Default: 0:ad(0,a)fsck boot: If I enter a question mark, I get a listing of the root filesystem's contents. (If the disk format were truly unknown, how is this possible?) This problem appears to be identical to the one posted by cell on 3/14/05, so this would seem to be a repeatable problem. Because this is a test box, I could just flatten it and reinstall, I would rather do a graceful recovery. Any suggestions on how to accomplish this would be appreciated. Note: Any suggestions involving using Release Disc 2 are problematic. For some reason, the iso will not burn; the process hangs immediately. I downloaded it from four different sites, including ftp.freebsd.org with identical results. (The other three disc images burn correctly.) Thanks for your time, stheg __ Do you Yahoo!? Yahoo!
