So I'm working on this RSX11M+ system here and while working I ran
myself out of file headers. Using the HOME /MXF command I was able to
increase the number of headers, but only up to 4090. or so. Trying to go
to 4100 gave me an error saying there were not enough system blocks or
something. Currently I have 830 headers, but that's not enough in the
long term.
The volume has 541,944 blocks total, with 150655 in use. This is a
system I generated on a smaller disk, then copied to the pdp11, then
backed up with BRU MU0:=DU0: then restored to a larger blank disk.
I guess the question is can I extend the number of blocks without having
to re-init the system disk? I suppose I could flatten it by taking the
system down to single user (shutdown, then p to start with the volume
dismounted, mount the volume /for, then BRU mu0:=du0:), then format the
volume with a really big assed MXF value, then restoring the tape, but
would that flatten the volume info? Or do I need to just man up, put a
second ESDI drive on this monster, copy the files to the second drive
then format the first (big) volume right, copy the files with PIP, and
do a VMR again to write the boot block?
Or is there a better way to backup and restore the volume without doing
an image backup using /for?
Been a long time since I've done this stuff. Thanks!
