fsck many bad blocks

mjolnir · 01-11-2004, 03:27 PM

I am dual booting obsd 3.4 and mdk9.1 on a toshiba sat.
While trying to configure X on bsd I managed to lock it up
and had an unclean shutdown. I finally got it to boot again
but /dev/rwd0h is full of bad blocks. It won't do an automatic
fsck and tells me to do it manually. I have worn out two fingers
hitting y and enter with no end in sight! Any help appreciated.

Boot a rescue CD or rescue floppy to run fsck.
Use the -a option and fsck will stop asking you to reply for every error it finds.

If you do not have a rescue CD or floppy, I think you can boot up in single user mode (do 'INIT 1'), then you can run fsck manually. (I hope I remember well; it was so long ago I had to do this...)

/usr/bin/yes | fsck

IIRC that's how it's done.

By the way, you should mount all your partitions with "softdep". That is similar (and some say, better!) than file system journaling in Linux (RiserFS, EXT3, etc).

Here's an example from my /etc/fstab

Code:

/dev/wd1a / ffs rw,softdep 1 1
/dev/wd1g /home ffs rw,nodev,nosuid,softdep 1 2
/dev/wd1h /tmp ffs rw,nodev,nosuid,softdep 1 2
/dev/wd1f /usr ffs rw,nodev,softdep 1 2
/dev/wd1d /var ffs rw,nodev,nosuid,softdep 1 2
/dev/wd1e /var/log ffs rw,nodev,nosuid,softdep 1 2
/dev/cd0c /mnt/cdrom cd9660 ro,noauto
/dev/fd0c /mnt/floppy msdos rw,noauto

Thanks for the replies guys. I have run fsck several times but I keep getting a warning when I
reboot about a dirty file system at /home. Something like: DIRECTORY ?: EMPTY BLOCKS
Adjust length(yn). No matter how I answer it I always end up with a message to rerun fsck.
I think I will probably just do a reinstall since I need the practice anyway. I googled softdep
and it looks promising chort thanks for the tip.

Update

I did a reinstall and things are fine now. I also added "softdep" to my fstab.
A lot to learn about this OS but I think it will be worth it.
