Unfortunately no one can be told what fun_plug is - you have to see it for yourself.

Re: cleanboot 1.0 for DNS-323 / CH3SNAS

I always shut the box down with "touch /tmp/shutdown". I believe that this is the same thing that the button on the front panel does.

I also get ext2 warnings but these are normal.

Code:

EXT2-fs warning: maximal mount count reached, running e2fsck is recommended

I would need to do a manual check to get rid of them.

Re: cleanboot 1.0 for DNS-323 / CH3SNAS

Is there some general pseudo-code for what cleanboot does? As I start adding different programs, funplugs, optware, and so forth, how can I be sure that cleanboot will properly close everything?

There's another thing that would be great on shutdown/reboot (haven't seen that in your scripts):

Code:

chmod 0777 /mnt/HD_a2
chmod 0777 /mnt/HD_b2  (if present)

This has bitten me several times. See also
http://dns323.kood.org/forum/t407-Runni … THIS..html

Note tehres a small bug in cleanboot.sh - you check for existence of /mnt/HD_b2, and if it exists you chmod 0777 /mnt/HD_a2, not _b2.

Re: cleanboot 1.0 for DNS-323 / CH3SNAS

Hi , I have a DNS-323 with firmware 1.07, fun_plug 0.5 and a 1 HD 500 GB, I read when you shutdown the system from front button or from the WebUI , the disk isn't unmounted in the right way if you have funplug installed... so i installed cleanboot 2.05 for ffp 0.5 to prevent problem.... but i have an issue.

executing the command shutdown via telnet the system isn't shutdown but i does a reboot... why this happens ?? how can i solve ??

thanks

Re: cleanboot 1.0 for DNS-323 / CH3SNAS

I could not get cleanboot working on my machine either.   In fact, I got locked out of the machine and it took a while to figure out how to break back in.   

In the end, I ended up writing some scripts of my own to provide similar functionality.

Re: cleanboot 1.0 for DNS-323 / CH3SNAS

Sure, I'm happy to share and have your suggestions.
At the moment, the scripts are embarrassingly hackerish, but they do work for my purposes.
The basic idea is to have a fake-up of run levels.

I'll try to clean up/pull together, ... over the next couple of days and post them to this thread, but I can describe the basic elements so you can decide if it's really all that interesting for your purposes.

There are four pieces to this solution:

i) the utelnetd telnet daemon is tiny enough to live on the ram disk and not hurt anyone.
ii) fun_plug copies utelnetd onto the the ram disk and starts it.   
iii) There is a user, toor, which has root privledges,
     uses /bin/sh as its shell and has only the ramdisk in its path.
iv) Finally, there are scripts, rc.lowest, rc.reboot and rc.shutdown that are also copied to the ramdisk
    at startup and try to fake-up the idea of run-levels.   lowest should be like single, ...
    rc.lowest brings the machine into an approximation of single user mode with all of the disks   
    unmounted if possible.   At that point, you can log in as toor using telnet and fsck or whatever
    other low level tasks to your hearts delight.   You can then remount the ffp stuff read-only and
    run smarttools, ...
    The reboot and shutdown scripts try as hard as they can to kill everything, unmount, ..., but
    if they fail, they go into the pseudo single user mode to let you manually unmount.

Right now, going into single user mode is pretty reliable, but complete shutdown and reboot without manually entering the single user mode is a little flakey, but works most of the time.

Re: cleanboot 1.0 for DNS-323 / CH3SNAS

Here are the scripts as requested:

This stuff is at the "it works on my system, but it's otherwise untested." state.   

First, you will need the utelnetd binary from the how-to telnet page.
This stuff does not work without it.

Second, you will need a user with root privleges which uses the /bin/sh
shell.   (recall you need the "secret code" 5784468 to get a prompt).
Mine is called "toor"
--------------------------------------------------------------------------
adduser toor
usermod -u 0 -g 0 -o -s /bin/sh -d /root toor
--------------------------------------------------------------------------

Third, you need to have ffp installed and accessible through /ffp

You will need a symlink /custom which points to a directory on disk with bin and log subdirectories.
Put chlevel into /custom/bin
You will need a symlink /local pointing to a directory on disk with a bin subdirectory.
Put utelnetd in /local/bin

Note that all of the directories should be changable by variables in the
fun_plug or chlevel scripts.

Here is a fun_plug script derived from ffp version 0.5 with minimum changes necessary to get this to work.

Re: cleanboot 1.0 for DNS-323 / CH3SNAS

I completely redid my script so that it implements something that looks alot like system V run levels with
names instead of numbers.    I can bring the machine down to a mode where only fancontrol and utelnetd are running with the kernel processes and all disks are unmounted.   From there, I can do whatever I want and get back to a fully running system.   Here is the new script.   It's much simpler, more robust and more easily customized than the old one.     At some point, I'd like to add a pseudo "run level" that implements Fonz's tmpfs for system maintenance idea.

Code:

Re: cleanboot 1.0 for DNS-323 / CH3SNAS

Hey guys,

after installing cleanboot2.0.0 from the first post on my ffp0.5 the box can't be reached anymore. After it restarts it rejects any connection, does anybody knows a way wo to get in again?

EDIT: It seems that cleanboot only purged my hostname, so it had none. Under its regular IP it was rechable. So problem is fixed!

Re: cleanboot 1.0 for DNS-323 / CH3SNAS

New version 2.1 published, basically I've included all fixes in the bugfix releases 2.0.4 & 2.0.5 done by marinalink and SilentException (thanks guys!) plus some suggestions found in other comments.
Should work fine in DNS323 & CH3SNAS using fun_plug 0.5.
First post & wiki updated with instructions.

* How to shutdown your box after cleanboot has been installed:

telnet or ssh into your box and issue the command 'shutdown' or 'halt'.

NOTE: at the moment this is the only way to cleanly shutdown, if you do it either via the web panel or by pressing the button, the hard drives will not be cleanly unmounted.

.
.
I have figured out a way to allow the shutdown command to be called from turning off by using the power button. Pushing power button eventually calls the raidstop script which can be manipulated to initiate Cleanboot's shutdown command.

See my new thread here: http://dns323.kood.org/forum/viewtopic.php?id=5346

Re: cleanboot 1.0 for DNS-323 / CH3SNAS

I am having problems. I have installed the latest version of cleanboot on my DNS-321, but I am now getting "not found" whenever I try to halt, shutdown or reboot from an ssh session:

/mnt/HD_a2/ffp # reboot
/ffp/bin/sh: reboot: not found
/mnt/HD_a2/ffp # halt
/ffp/bin/sh: halt: not found
/mnt/HD_a2/ffp # shutdown
/ffp/bin/sh: shutdown: not found
/mnt/HD_a2/ffp # do_reboot
/ffp/bin/sh: do_reboot: not found

The following shows that I do have the file "do_reboot":

root@dlnas:/usr/sbin# which halt
/sbin/halt
root@dlnas:/usr/sbin# ls -l /sbin/halt
lrwxrwxrwx    1 root     root           19 Apr 27 17:00 /sbin/halt -> /usr/sbin/do_reboot
root@dlnas:/usr/sbin# ls -l /usr/sbin/do_reboot
-rwxr-xr-x    1 root     root         3632 Apr 27 17:00 /usr/sbin/do_reboot
root@dlnas:/usr/sbin# which do_reboot
/usr/sbin/do_reboot
root@dlnas:/usr/sbin# do_reboot
-sh: do_reboot: not found

Any help would be greatly appreciated.

@marcaronson408: make sure /sbin and /usr/sbin are on your $PATH, you can check by typing 'echo $PATH'.

Thank you for that suggestion. Unfortunately, that is not the problem as those two directories are already on my path:

root@dlnas:/mnt/HD_a2/ffp/home/root# echo $PATH
/ffp/sbin:/usr/sbin:/sbin:/ffp/bin:/usr/bin:/bin

I am wondering if I am missing a shared library -- when I execute "file do_reboot" I see the following:

root@dlnas:/usr/sbin# file do_reboot
do_reboot: ELF 32-bit LSB executable, ARM, version 1, dynamically linked (uses shared libs), stripped

Re: cleanboot 1.0 for DNS-323 / CH3SNAS

I have exactly the same problem as marcaronson408 on my new DNS-321. Does anyone know how to get this to work?
Thanks

Re: cleanboot 1.0 for DNS-323 / CH3SNAS

I am using DNS-323 with latest firmware 1.09. After installing Cleanboot 2.1, I cannot browse Volume_1 and Volume_2 folder from Windows Explorer. Moreover, I also cannot get other installs, i.e., Transmission 2.1 and OpenVPN to work either. I either have permissions errors, or in the case of OpenVPN, the start-up script starts only after I type the reboot or shutdown command. As a result, the shutdown process is interrupted and it does not shutdown unless I use the Web UI.

I am using to WD 2TB drives in standard configuration, i.e., standalone drives, no RAID.

Re: cleanboot 1.0 for DNS-323 / CH3SNAS

Howdy - I've got a DNS-323 with two drives running independently, and currently they both seem to need a fsck as they fail the scandisk check...  I've had FFP installed for years and installed Cleanboot some while ago, but I forget to use it or the DNS will crash on occasion, or just lose power, etc. so it's not hard to figure out why.

Anyway I've been looking into the various ways to do a fsck, but with 2 small kids in the house nowadays I just don't have time to sit down and even read the instructions properly!  I'm wondering if there's any reason why I can't just pull out the drive, pop it into a SATA-USB docking station and connect it to a Linux machine, and run a standard fsck that way?

Back when I ran RAID there would be the occasional problem with connecting the drives to another system and then putting them back into place, and so on, but I don't think that would be a problem now?  I'm running firmware v1.08 and the fun_plug script is marked with the date 2008_4_13 for what that's worth.

I use one 320GB drive to store files and a larger, 1TB drive, to back up both the smaller drive and the various desktop machines around the house via NFS links and a Time-machine-like rsync script I cobbled together back when I had more than a few brain cells to rub together... I could back up each drive before running rsync by just cloning it (the SATA dock I use has two ports and can do cloning even easier than a dd) but I also recall the DNS-323 somehow keeps track of drive serial numbers so I hesitate before even considering a direct clone of a drive as an effective plug-in backup solution (even though I know the files themselves would be recoverable enough).

So anyway, I throw myself on the mercy of those who have more reliable knowledge of the 323 than I do - can I just shut down the server, pull out the drive and attach it to my Linux system to fix up whatever little bits of cruft that have crept in, then plug it back in without any hassle? (provided all the errors are minor and fixable)

Re: cleanboot 1.0 for DNS-323 / CH3SNAS

I'm a little confused with the progress of this now. Does the box cleanly shutdown when pressing the button on the front or not? There are posts here where people say they've worked out how...
Also, does it cleanly shutdown/restart from the web UI?

Is issuing the "halt/reboot" commands the same as using the web UI - even without cleanboot installed?

Re: cleanboot 1.0 for DNS-323 / CH3SNAS

I installed cleanboot-2.1-ffp05 for my DNS-321 and found out the binary wasn't compatible (executing it would give me a "not found" error message).

After seeing the source code is only calling the cleanboot.sh script, I basically bypassed it by renaming /ffp/share/cleanboot.sh to do_reboot and editing it to handle the appropriate args.  That, and some tweaks to the startup script to address the changes seems to be working for me, and I think will be more compatible w/ future firmware since it doesn't have a compiled piece to worry about.

To test,  restarted and shutdown via "restart" and "shutdown" links, and also utilized the web based shutdown and restart.  In all cases, after bringing up the NAS, I didn't get any new e2fsck errors from dmesg.  Is this the only way to see that the umount was done properly?

Re: cleanboot 1.0 for DNS-323 / CH3SNAS

jboo, I'm in the same boat could you post some more detailed info about the changes you made to cleanboot.sh script and the startup or post the files themselves so I can take a look. Thanks!
