disable auto-mounting on boot time

[newbiefan]

@al37919

Man - many thks, it's exactly what I need!
Now, the pre-shutdown make sense - and the best is, that everything what I want to achieve is running well and stable on my 2 asus routers.
Ok, I've bricked one with (guessing) samba under heavy load, even the serial console was not working any more - but this was solved with nice -n-17.
And now the unclear umount is solved!

Thanks again, maybe I start now my planned project, mc on asus-rs232

Yeah, it now works without swapon -a and mount -a, my fstab is:

/dev/discs/disc0/part1  none       swap    sw                      0 0
/dev/discs/disc0/part2  /opt       ext3    noatime,nodiratime      1 1 

and my post-boot is:

#!/bin/sh

if [ ! -d /dev/discs ] ; then
   insmod scsi_mod && insmod sd_mod && insmod usb-storage
fi

i=0
while [ $i -le 30 ] ; do
   if [ -d /opt/etc ] ; then
      break
   fi

   sleep 1
   i='expr $i + 1'
done

sleep 10

/opt/etc/init.d/rc.unslung 

I had to add sleep 10 before calling rc.unslung, otherwise it would not start samba and xinetd

[al37919]

you can simplify it even further:

#!/bin/sh 
 
if [ ! -d /dev/discs ] ; then 
   insmod scsi_mod && insmod sd_mod && insmod usb-storage 
fi 
 
sleep 15s
 
/opt/etc/init.d/rc.unslung

thx @al37919 and thx @newbiefan

your hints were perfect. with fstab my mount problem is solved.

especially thx for the pre-shutdown hint, what solved following problem:

i formated my hdd with fdisk and edited the fstab file as described and afterwards i made the common "flashfs save && flashfs commit && flashfs enable && reboot"

after booting process was finished i wondered why my just created partition was not able to be mounted, and even the partition seamed not to be formated. and now i am sure it was just the reboot command. some data wasnt written to hdd just in cache i think.


how do you remove usb devices safely btw?

[newbiefan]

That was exactly my problem, I had to mount a bunch of usb sticks and have not been able to unmount them in a correct way. Several sticks had problems with that (after a while).

When you need to unmount (which means to remove=linux) a usb storage device, you have to remount this device in read only mode as al37919 stated.

A regular umount doesn't work proper, maybe fstab handling (process) is one of the reasons.

I have sort of a related problem. During the startup sometimes I can see this mount is shown on my system

/dev/discs/disc0/part1 151705660 20985876 123013576 15% /tmp/mnt/disc0_1

I did not specify this mount and I do not use fstab, this file does not exist on my system.

I would like to know where it comes from and how to get rid of it?

this is what I mount in the post-boot:
mount /dev/scsi/host0/bus0/target0/lun0/part1 /opt

I have this line in my post-mount:

/bin/mount -o bind,sync,noatime,rw /tmp/harddisk/opt /opt

may it be related?

Thanks.

[al37919]

if you look carefully, you'll find that /dev/discs/disc0/part1 is a symlink to /dev/scsi/host0/bus0/target0/lun0/part1

You can just forget about this junk mounting. It doesn't harm anything.

If you do care about it, create fstab . Then it will disappear.

[piezomotor]

It doesn't harm anything.

Yes it does in some way...

What is actually happening is that when /tmp/mnt/disc0_1
is mounted the stupid-ftpd would start somehow and as the result all of my files are exposed to WAN! I was trying to run a search to find this stupid-ftpd via Samba (from Windows) on the whole drive and could not find it...

I did not get it where it is located and how it opens the 21 port to the WAN when it is not open in my post-firewall?

Do you know?

[al37919]

if you have /tmp/mnt/disc0_1 it means that you're using some of the last previews. Install preview 12. There is no stupid-ftpd in it anymore.

Thanks, Could you please give me the link?

I have the same problem that the /tmp/harddisk always mount first.

Where should I save the fstab?

I strongly suggest to search forum........
fstab is stored in /tmp/etc
