Preinit help - URGENT!!

I'm in the middle of installing Preinit. I've followed the instructions on the website, and so have done this:

ftp -s:install.ftp <empeg-hostname>

mkdir /programs0
mkdir /programs1
mke2fs /dev/hda2
mke2fs /dev/hdc2
mount /dev/hda2 /programs0
mount /dev/hdc2 /programs1

Now when I try to make my drives read only (ro or rom) I get this error:

mount: can't find /drive1 in /etc/fstab or /etc/mtab

What have I done wrong, and how do I fix it?

Thanks.

My second drive is not hdc2, but is hdb2 apparently

Not sure why, but maybe this should be reflected in the instructions somewhere???

I get this error:

mke2fs /dev/hdb2

mke2fs 1.19, 13-Jul-2000 for EXT2 FS 0.5b, 95/08/09
Could not stat /dev/hdb2 --- No such file or directory

The device apparently does not exist; did you specify it correctly?

And I still get the error above as well.

That's odd. Usually both hdb2 and hdc2 exist, both pointing to the same thing, for the sake of consistency with the MkIs.

Have you installed other hacks?

All I've got installed is Beta13-Dev, Hijack, and the games that I am trying to get onto the Hijack menu.

The Mk1 empegs had 2 ide channels, so disks would be /dev/hda and /dev/hdc.
The Mk2 empegs only have 1 ide channel, so they are /dev/hda and /dev/hdc

However, the Mk2's have had the device node for /dev/hdc changed to point to what would normally be /dev/hdb. This enables Mark2 software to be consistent with Mark1 software..

But that shouldn't be the cause of your problem;

What does cat /etc/fstab reveal?

mount: can't find /drive1 in /etc/fstab or /etc/mtab

IIRC drive1 isn't in fstab as the player mounts it directly via its dev entry. I definitely remember adding it to mine after adding a second disk. So the question would be did this work before and if so, why?

empeg:/empeg/bin# cat /etc/fstab
#
# /etc/fstab
#
# <device> <mountpoint> <filesystemtype> <options> <dump> <fsckorder>
/dev/hda5 / ext2 defaults,ro 1 1
/dev/hda4 /drive0 ext2 defaults,ro 1 1
none /proc proc defaults

Hmm, I saw the same thing happen to me once upon a time (I believe when I upgraded to beta13), and never really worked out what caused it.

Anyway, here's the fix:

rw
echo "/dev/hdc4 /drive1 ext2 defaults,ro 1 1" >> /etc/fstab
ro


It's *very* important to ensure that you use ">>" and not ">" in the above line. ">>" tells the shell that the input is to be concatenated (ie appended) to the existing file. ">" would overwrite the file completely.
If you're at all unsure, then perhaps backing up the /etc/fstab file first would be a good idea;


cp /etc/fstab /etc/fstab.bak


While you putting that line in, you might also want to consider also;

echo "/dev/hda2 /programs0 ext2 defaults,ro 1 1" >> /etc/fstab
echo "/dev/hdc2 /programs1 ext2 defaults,ro 1 1" >> /etc/fstab


which will make ({re|un})mounting /programs0 and /programs1 easier.

I'll give it a go.

Many thanks.

That seems to have done the trick

Out of interest, what do those commands do?

Thanks.

They append the stuff inside the quotes to the /etc/fstab file. This in turn tells the system to automatically mount the file systems specified on the lines at boot (with default options, but read-only). It also simplifies later mounts by having the options set and which mountpoint and partition that belongs together, specified in advance.

If you had after boot unmounted the /drive0 partition, you can the mount it by simply saying "mount /drive0" instead of also having to specify the options, filesystem type and partition...
