Re: [Testbed-admins] Booting error in Customizing the Generic Image

["Cheng Cui" <ccui1@tigers.lsu.edu>]

Hello Ryan,

On trying the mount, I get this error:
# /etc/testbed/mount_bsd_slice /dev/sda5 /mnt
Unable to get offset/size info for /dev/sda5

Besides, I have tried the straight mount command with file system
option:
# mount -t ufs -o rw,ufstype=44bsd /dev/sda5 /mnt
mount: mounting /dev/sda5 on /mnt failed: No such device or address

# mount -t ufs -o rw,ufstype=ufs2 /dev/sda5 /mnt
mount: mounting /dev/sda5 on /mnt failed: No such device or address

Because I am mounting partitions based on your previous instruction,
that BSD6.4 generic image partition should be mounted as:
/etc/testbed/mount_bsd_slice /dev/sda5 /mnt
/etc/testbed/mount_bsd_slice /dev/sda7 /mnt/var
/etc/testbed/mount_bsd_slice /dev/sda8 /mnt/usr

And Linux partition should be mounted as: 
Mount -t ext2 /dev/sda2 /mnt2

As far as I know, the sda3 is Linux swap, then what is sda1 used for? Am
I right?

It's up at http://www.emulab.net/downloads/linux_boot.tar.gz.  You can
just extract the linux_mfs.tar.gz tarball into /tftpboot like before
and ignore the rest of the stuff (nothing else has changed).

The mount_bsd_slice script will automatically figure out which Linux
partitions are mapped to which BSD partitions, and mount all of the
UFS partitions in the BSD slice in the correct order.  It should even
work if you have more than our standard 3 BSD partitions (/, /usr, and
/var).

Unfortunately, you'll need to unmount everything manually.  Run
'mount' to see what's mounted underneath the mountpoint you passed to
mount_bsd_slice and unmount each partition manually.

Let me know if you have any problems.
