So it turns out my issue was that the cd actually had a UFS not CDFS
(ISO9660) filesystem. I was able to get the CD to return from the mount
command as if it were mounted, but got very strange behavior (only a few
of the directories, and none of the files showed up).
The "read-only" is normally implicit in "-t cfds"...certainly this is the
behavior with every other iso9660 cd. In fact, every other cd mounts just
fine if you give mount no options at all:
mount /dev/rzNa /mnt
Mount appears (as it does on many other *nixes) to actually try to
determine the FS type. Perhaps this is not the case. Evidently, the UFS
type confuses it.
The commands I was trying were:
mount /dev/rz4a /mnt
mount -t cdfs /dev/rzNa /mnt
mount -r -t cdfs /dev/rzNa /mnt
None of these worked. As soon as somebody clued me in that this was a UFS
file system, then:
mount -r -t ufs /dev/rzNa /mnt
worked like a charm.
I was unable to find out that this cd was UFS (unlike every other cd in
the distribution) anywhere in the documentation. This kind of surpised me
since DEC provided such nice notes about booting the distribution cd from
the boot prom. I would urge them to include this in the instruction.
FWIW, I just don't see why they use UFS (presumable because it's
bootable)...many other bootable distributions (Solaris and Linux that I
know of) use ISO9660.
Regards, and MANY THANKS to the five folks who knew the UFS trick and
responded within five minutes! I only attend to two Alphas running Tru64,
and this was the first time I've ever been on this list. I've never been
on another list which was so responsive.
