Установка OpenmediaVault на CF-карту с системой voyage linux (Debian) read-only

Проверено на версии OMV (2.6.3) Скачиваем и устанавливаем дистрибутив Voyage linux ( http://linux.voyage.hk/ ) после установки перезагружаемся и заходим в систему
voyage login: root

делаем систему для записи
/usr/local/sbin/remountrw

добавляем репозиторий OpenMediavault '/etc/apt/sources.list.d/openmediavault.list'
deb http://packages.openmediavault.org/public/ ix main binary-i386

для OpenMediaVault 0.3 версии

Может как раз создать Embeded систему на базе Voyage linux?
Плюсов полно: debian основа, может работать с флешки и спокойно обновляться, свежее ядро linux.
votdev что скажешь на это? у меня уже работает такая связка!

Thanks for you guide.

Could you please state which version of Voyage Linux you are using. The newest version is using linux kernel 3. If I use this I can't get it to work, so could please tell me which version of Voyage you use.

arturmon · 29. Juli 2012

using a Voyage-8.5 kernel is 3.2.17. What you can not?
added a little guidance. added fix for drawing graphs. Without these patches nor any charts!
also added direct links to download Voyage Linux, but difficult to find a 64 bit version.

sbp · 29. Juli 2012

Thanks for you help.

If I try to use the current Voyage version (0.85) everything goes fine until I try to install openmediavault. Then this error pops up:

root@voyage:~# apt-get install openmediavault
Reading package lists... Done
Building dependency tree
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created

The following information may help to resolve the situation:

The following packages have unmet dependencies:
openmediavault : Depends: php5-pam but it is not going to be installed
Depends: scponly but it is not installable
E: Unable to correct problems, you have held broken packages.

I suspect it has something to do with the sourceslist - what do you have in here. In mine I have the following:

deb http://cdn.debian.net/debian/ wheezy main contrib non-free
deb-src http://cdn.debian.net/debian/ wheezy main contrib non-free

deb http://packages.openmediavault.org/public/ omnius main

Thanks

OK, Finally I managed to install OMV 0.3.18 on Voyage Linux. I made the following observations and changes to the original procedure;

1.
You need to use version Voyage Linux version 0.85 Live CD.

2.
make this file /etc/apt/sources.list.d/openmediavault.list
which contain this line
deb http://packages.openmediavault.org/public/ omnius main

3.
Then:
apt-get update
apt-get install openmediavault-keyring
apt-get install postfix
apt-get install locales
.................. I skipped this part: dpkg-reconfigure locales
...................I skipped this part: specify the locale, 179 and 343
apt-get install openmediavault

4
Reboot and return the system back to read-write by typing : remountrw
Then go in WebGUI OpenMediaVault and turn on SSH access (or start the SSH server manually, by /etc/init.d/SSH start)

5.
Then via WinSCP or nano or by ssh and change the file '/etc/default/voyage-util'
So the line VOYAGE_SYNC_DIRS="" should be changed into: (OBS different from the original post, otherwise I couldn't login via webgui)
VOYAGE_SYNC_DIRS="var/lib etc/openmediavault etc/samba usr/share/php/openmediavault"

6.
Now it starts, but Voyage linux will not start in read-only mode because "mount is busy" and therefore operates in read-write mode - which is not what we want, because it will tear down the CF-card very rapidly.
It turned out that we need to stop the anachron service, then go into read-only mode, and then restart the anachron service.
Therefore I made a script that stops anachron at startup, go into read-only mode and restarts anachron:

You need to make this file: "etc/init.d/restart_anacron"

The content of this file is:
#!/bin/sh

### BEGIN INIT INFO
# Provides: restart anacron
# Required-Start: $remote_fs $syslog $time
# Required-Stop: $remote_fs $syslog $time
# Default-Start: 2 3 4 5
# Default-Stop: 0 1 6
# Short-Description: Stops and Restarts anac(h)ronistic cron
### END INIT INFO
# /etc/init.d/anacron: start anacron
#

echo "Stop anacron and then sleep 2"
/etc/init.d/anacron stop
sleep 2
echo "try to remount as read only"
/usr/local/sbin/remountro
sleep 2
echo "Start anacron again"
sleep 2
/etc/init.d/anacron start

Then
update-rc.d restart_anacron defaults

you've done what I have not had time. I congratulate a great job. recording on CF was minimal, so I started rebuilding the kernel (it is clipped it turned out).

sbp · 4. August 2012

Hi arturmon

How are you doing, did you succeed in rebuilding your own kernel, and are you able to run in read-only mode (no writing to the CF-card)?

Here at my end OMV seems to run very good it has been running without any problems for more than 4 days, without a reboot (in read only mode).
I have also installed Logitech Mediaserver on the CF-card and it seems also to be fine in read-only mode.

It would be nice if someone could make a simple OMV plugin for Voyage Linux, so that we could change the mode from "read-write mode" to "read-only mode" by just pressing a button in OMV webgui (The command is remountro = "read only" and remountrw = "read-write mode"), because if you want to change anything like Samba, add a new user or add a new drive, we off-course need to be able to save these changes, therefore, you need to go into read-write mode to save, and then again into read-only mode

Did anybody try to run twonkyserver on Voyage? Not shure how happy this would be on an RO FS ...

if you knew how, long ago wrote a plugin to switch modes.

Hi do you mean that you already have written such a plugin - then I would love to try it.
Or do you mean that you think it will difficult because it is a long time ago you tried to write a plugin (sorry English is not my native language)- I hope that you willl try.

английский тоже не мой родной язык. как писать плагины для OMV я к сожалению не знаю. может кто другой знает )
English is also not my native language. how to write plugins for OMV, I unfortunately do not know. can anyone else knows)

el_viejo · 25. August 2012

hi guys,

i am really excited about your approach to save flash memory lifetime using voyage linux. it takes a little more time to set up the system but it works. and even the newer kernel makes my server consuming less energy. great work. it would be perfect if somebody who knows how to do it could write a r/w plugin for omv to allow full control by the webgui.

maybe the idea of using a r/o filesystem could influence the whole development of openmediavault. would be nice to know what the developer thinks about it.

thank you very much and keep up the outstanding work

while setting up omv on voyage linux i tried to enable nfs file services. after clicking ok on both pages (nfs settings page and nfs shares page) i get the following error message in the webgui:

Code

of course voyage system is mounted in r/w mode. after investigating i found out it has to do with starting/restarting the nfs-kernel-server. when i use the command /etc/init.d/nfs-kernel-server restart in a ssh shell on my server i can see the shares but by the webgui it does not work properly. maybe somebody has a clue what to do to make it work from the webgui and get rid of the error message.

thanks and greetings

peter

el_viejo · 26. August 2012

it is really strange, after several reboots it seems the problem went away. i am now able to enable/disable the nfs server from the webgui when the file system is mounted r/w. i have no idea what the problem was. anyway...

another thing i found out today is that after boot the file system is not getting remounted r/o. it stays r/w and i have to access the system via ssh manually calling remountro. i followed all steps of the given howto in this thread but it seems something prevents execution of restart_anacron during boot up or something prevents the remountro command at boot time. still have to find out what it is.

greetings

peter

trix · 27. August 2012

so, how is it better than usual install with ramlog? (also moved to /var/tmp some /var/lib stuff )
do we have any metrics/benchmarks to compare?

arturmon · 30. August 2012

Из плюсов вижу : новое ядро, вся система установлена R/O (если настроенно), занимает мало места.
по поводу перевода корня R/O, у меня получился несколько другой скрипт так как пришлось перезапускать побольше служб. Но пока решил оставить корень rw интересно сколько проживет CF в таком состоянии.
про настройку NFS не подскажу почему так получилось но думаю это тонкости Voyage linux надо на их сайте смотреть.

Jetzt mitmachen!
