Hi James,

Do you have an OS DVD?
Boot from that and try to create the device file using mknod. Just a suggetion.

Better to first ask, then do anything.

You did delete the file "lvol1" only , right?

So your problem is bigger since you did a shutdown. Without shutdown the solution would be to simply recreate the file.

Now you probably need to boot from install DVD (recover shell) and repair from there.
