Hello
I have tried to chceck for badblocks on my / but I did not find
badblocks
program on LiveCD and there is no option to install it. This is very
useful
utility, please add it as part of LiveCD
Also there is a problem with DHCP based workstations using LiveCD -
although interface gets configured it is impossible to update
/etc/resolv.conf (by dhclient and by hand) and so this workstation
pretty
useless for IPv4 (is it more usable on IPv6?). Please update
Thank you

dd if=/dev/zer of=/dev/ada0
^^^ There's your "badblocks" program. Any hard drive made in the last
decade have been self-remapping.. Attempting to write to a bad block
will cause the hard drive to remap an unused sector into it's place,
until the drive runs out of said "unused" backup sectors, and at that
time, will begin simply begin just "losing" storage space... IE the
number of total sectors on the drive will begin to shrink.
/dev/zero
Badblocks is outdated for more than 17 years I guess
The dd mentioned above will let the firmware remap all bad sectors until
there are no spare sectors left (and wipe anything on disk as a bonus
;then you can begin to think about replacing your harddrive.
As for DHCP, it works for me when booting from a netinstall for instance
or going to fixit.
Tomek, please try to describe more accurately what you are doing and try
to accomplish
As I get ffs_valloc kernel panic on my / I want to check for badblocks but
cannot do that from the system itself so I need another FreeBSD instance to
run badblocks on unmounted /. There are no badblocks on LiveCD and I cannot
simply download it with pkg_add -r. Installing another system just to test
existing one seems silly. It would be nice to finally have swiss army knife
on generic LiveCD FreeBSD install, not using linux windows hirens etc :-)
I have just started dd if=root of=root from LiveCD, Ill let you know if
that worked :-)
I will be surprised what that will do for you
I have lloked at the picture and all I can come up wih is either bad
hardware or a very strange software/system configuration.
Good luck
Please reply to this list if any
