Here is the error message we are getting when expanding one of the lvm root
directories. When we try to reboot the server it goes to a disabled wait or
asking for a root password which it keeps rejecting. We were able to expand
the root file system on SLES 12 SP3 with no issues.

One way to do that is to specify "init=/bin/bash" on the IPL command. Of course
that means you have to do *everything* the system would have done for you
before it failed. But, if what you need is the biggest hammer you can find,
that's it.
