Yes.  The easiest way is to simply use 'mount_null /dev /mnt/2ndDisk/dev'
after mounting the second disk.

And, of course, to umount /mnt/2ndDisk/dev before umount /mnt/2ndDisk.

Anything you chroot to will need its own devfs mount, either using
mount_null of /dev onto the target dev or (more directly) mount_devfs
on the target dev.

:but my /dev on the second disk has more files than /dev on the first disk.
:I have updated the base system on the second disk also using chroot .
:Is it because i have not booted from the second disk after the upgade?

It's just because DEVFS is mounted on one and not mounted on
the other.  With DEVFS we no longer need anything in the dev
directory since the DEVFS mount will simply overload it.  An
all-new installation of the system will leave the original /dev
in the filesystem (prior to mounting DEVFS) empty.

An upgrade leaves the original contents of /dev intact.. not because
I want it to be intact (I'd rather delete it)... but because it is
difficult to delete it on a live system since we can't unmount DEVFS.
The only way to delete would be to do a localhost NFS export for /,
mount it somewhere else, and then the original /dev would be exposed
and accessible for deletion.

So, simply put, you have DEVFS mounted on top of one filesystem
but not on top of the other.  The original contents of /dev
is no longer relevant to the system now that we have DEVFS.

If you want to mount DEVFS in both places you can do so with
mount_devfs, or even mount_null.

That's because on one you have devfs mounted and on the other one you don't.

The lower/upper case problem has caught more then a few people.  I will
change the lookups in the disklabel code to use strcasecmp().

I have also noticed that the NATA driver seems to have changed disk
designations in the upgrade, and I don't know why.

Siju's main issue seemed to be from calling the partitions unused.
I think in that case we need to change DEVFS to actually make the
partitions available in /dev, even though they should have properly
been set to HAMMER.  Alex or I will look into it.

Initially when I put hammer there it didnt mount so I put unused there
so that it will mount.
I seem to miss /dev/ad4s1h and /dev/ad6s1h in my /dev.
Shouldn't i make them?

Can you try upgrading again or are the disks crucial for that?

What disk devices do you have in /dev?

Thanks for the quick response :-)

Hope the Data is still in there and it is a matter of making the
device file /dev/ad4s1h and ad6s1h :-)

undo does not work on directories, try hammer history


Any Idea how to get the data back?


it doesn't seem that /Backup1 or /Backup2 are mounted.  Did maybe your device 
numbers change and mount can not find the file systems?  What happens if you 
try to mount them manually?
