It seems probable that the problem described below--namely that
an ADVFS partition copied from 131 MB /dev/rz1a to 196 MB /dev/rz3a
still has the old size and an old file set name, is due to
a hybrid and interim boot situation. The backup copy of OS
on /dev/rz3a got updated instead of the main copy on /dev/rz1a.
Namely, the system is using the boot sector off of /dev/rz1a but
then mounting /dev/rz3a. This means that somehow it is getting
the partition and file set information off of /dev/rz1a and thus
thinks the domain is smaller than it really is, and that the fileset
still has the old name. Thanks to alan_at_nabeth.cxo.dec.com.
But now comes the question--how do I get back to having everything
on one disk again? It's impossible to vdump the new and improved
OS back to /dev/rz1a even in single user mode because you will
get a "device busy" error. I may have a good boot sector on /dev/rz3
but I don't know that for sure.
A third system disk, rz2, is available for the purpose and blank.
Any suggestions are appreciated.
