Steve,
Now I know I'm missing something. I tried following your advice, using the
disklabel utility running under the old kernel. From what you say below, I
assume you are referring to the 'fstype' parameter on the partition, not the
'type' parameter for the drive, correct? The drive type is MSCP, and the
partition fstype is 2.11BSD.
I tried changing the partition type with disklabel -e -r but, when I exited
vi, I got an error message saying that the type I'd provided was not valid.
Viewing the label (with disklabel -r) showed the fstype set to 'unknown'.
Just for grins, I tried modifying the drive type, too - no success there,
either. The disklabel utility isn't having any of that; again it claims
'unknown'.
Oh well, while I'm waiting for your reply I can rebuild my kernel with a
higher MAXUSERS parameter. :-)
Thanks -- Ian

the
following:
<banner for the image, date, time, etc.>
panic: iinit
no fs on 5/0
That says the kernel was not able to mount the root filesystem. The
earlier messages about the kernel build date, etc appear because
the kernel prints those directly from internal strings (and the
kernel is loaded by /boot who doesn't "mount" the root filesystem).
The times I have seen the 'iinit' panic
it's meant that the disklabel
was either missing _or_ that the root ('a') partition was not of
type FS_V71K. I SUPPOSE it's far fetched, but possible, that the
old kernel predates the check for the filesystem type, thus it ignores
the type of partition 'a' and assumes it's a valid filesystem.
If you have a copy of the standalone 'disklabel' program installed
in / you can boot that with
ra(0,0)disklabel
and examine the label that way. Or boot the tape and load the
utility that way. Using the old kernel and running disklabel
would work too. If the 'type' for the 'a' partition is not
'FS_V71K'
that's the problem.
