Upgrade Owncloud 9.0x to 9.1 in Synology NAS running DSM6

Update Owncloud in Synology

This is detailed guide for upgrading Owncloud 9.0x to Owncloud 9.1 in Synology NAS devices running DSM 6. Owncloud 9.1 has been just recently published, and I wanted to share my procedure for updating Owncloud. This process should be fine for minor, point or major version upgrades of Owncloud also going forward, unless big changes are introduced how Owncloud is operating.

Before starting to go through the steps, I want to emphasize that every system is different, and there may be aspects that you need to do and consider that I am not covering here. But hopefully I am able to provide enough information for you to understand the steps needed to consider on your side. So please do understand that this is not by any means a definitive guide for your upgrade process. But as I have received many questions in many contexts about the update and how to use the occ comands in command line in Synology NAS – I decided to share my process to you. My process might seem too thorough and detailed, but I personally like to be cautious in upgrading production systems.

Also please consider reading thoroughly the Owncloud 9 documentation section about updating Owncloud. As there are multiple options for doing the upgrade, mainly these:

  1. Package upgrade
    • This is not an option for Synology, as there are no packages we could use in synocommunity.
  2. Updater app upgrade
    • In practice we have here the same steps as in Manual upgrade, the difference is that the app is trying to automate the steps needed.
  3. Manual upgrade
    • This is my favorite, and my choice for updating Owncloud instance. You are in control of every step of the process.

The following pieces of text are from Owncloud 9 documentation to highlight the importance:

It is best to keep your ownCloud server upgraded regularly, and to install all point releases and major releases without skipping any of them, as skipping releases increases the risk of errors. Major releases are 8.0, 8.1, 8.2, and 9.0. Point releases are intermediate releases for each major release. For example, 8.0.9 and 8.1.3 are point releases. Skipping major releases is not supported.

Upgrading is disruptive. Your ownCloud server will be put into maintenance mode, so your users will be locked out until the upgrade is completed. Large installations may take several hours to complete the upgrade.

You should always maintain regular backups and make a fresh backup before every upgrade.

Then review third-party apps, if you have any, for compatibility with the new ownCloud release. Any apps that are not developed by ownCloud show a 3rd party designation. Install unsupported apps at your own risk. Then, before the upgrade, all 3rd party apps must be disabled. After the upgrade is complete you may re-enable them.

Upgrade Quickguide

  • Disable all third-party apps.
  • Make a fresh backup.
  • Upgrade your ownCloud (core files).
  • Run occ upgrade (optionally disabling the migration test).
  • Apply strong permissions to your ownCloud directories.
  • Take your ownCloud server out of maintenance mode.
  • Re-enable third-party apps.

 

Ok – let’s start the upgrade process. You can follow to whole guide exactly as I do it, or pick up parts and pieces as you see fit for your own process.

1)

Login into your Owncloud instance as administrator, and disable all non-official 3rd party apps you might have installed and enabled. Non-official apps do not have the tag ‘Official’.

Disable 3rd party apps

2)

List down for later purposes all the directories/paths where you have something you need or want to preserve in the upgrade.

Here is my listing:

Select Code
1
2
3
4
5
/volume1/web/owncloud/core/skeleton
/volume1/web/owncloud/apps/
/volume1/web/owncloud/config/
/volume1/web/owncloud/themes/
/volume1/owncloud/

I have included above paths, because I have:

  • custom skeleton files for new users
  • custom 3rd party apps
  • config.php
  • custom theme
  • Owncloud data folder

You also need to think are there any other modifications that you have made, that you possibly need to re-do after upgrade. I know that I have modified the owncloud .htaccess file for doing the permanent re-direction from http to https. So I will record that to my to-do list as well. After your first upgrade you should have all this listing ready, and this will not be a big hassle at that point anymore. You should also keep this list up-to-date, in case you do some other direct changes to Owncloud core files.

3)

Put your Owncloud instance into maintenance mode. This prevents new logins, locks the sessions of logged-in users, and displays a status screen so users know what is happening. There are two ways to do this, and the preferred method is to use the occ command, which you must run as your HTTP user. Here is how you run that in Synology DSM:

Select Code
1
2
3
sudo -su root
cd /volume1/web/owncloud
sudo -u http php56 occ maintenance:mode --on

(Note: In Synology DSM we actually need to use ‘php56’ instead of ‘php’ in the occ console commands for Owncloud.)

Owncloud enable maintenance mode

This is what your users should see once maintenance mode is enabled.

Maintenance Notification login page

4)

Let’s modify the Owncloud web folder permissions, to ensure that we don’t ran into issues during our upgrade process. I won’t do any modifications to Owncloud data folder, as no changes are required there. This is valid only if you have setup your data folder outside Owncloud web folder (and you followed my guide for installing Owncloud 9 to your Synology NAS).

Select Code
1
2
3
chown -R http:http /volume1/web/owncloud/
find /volume1/web/owncloud/ -type f -print0 | xargs -0 chmod 0777
find /volume1/web/owncloud/ -type d -print0 | xargs -0 chmod 0777

Assign Owncloud permissions

5)

Let’s take the fresh backups of the whole Owncloud instance currently in use.

Please modify paths and db names accordingly for your setup. I have in my example following paths:

  • Owncloud install folder: /volume1/web/owncloud/
  • Owncloud data folder: /volume1/owncloud/
  • Backup files location folder: /volume1/bckup

Owncloud core files and Owncloud Data files:

Select Code
1
2
rsync -ax /volume1/owncloud/ /volume1/bckup/data_owncloud-dirbkp_`date +"%Y%m%d"`/
rsync -ax /volume1/web/owncloud/ /volume1/bckup/web_owncloud-dirbkp_`date +"%Y%m%d"`/

This will replicate you Owncloud web and data folder into backup folder appended with date.

Owncloud Database:

Select Code
1
mysqldump --lock-tables -h localhost -u[dbadmin] -p[password] [owncloud database name] > /volume1/bckup/owncloud-sqlbkp_`date +"%Y%m%d"`.bak

Replace [ ] parts with your ‘dbadmin username‘, ‘password‘ and ‘owncloud database name‘. This will dump your Owncloud database into -bak file appended with date.

Now you have backed up your whole Owncloud installation to your backup folder. See below screenshot for example execution and what files were generated into the backup folder:

Take Owncloud backup

6)

Now shut down your web server in Synology:

Shutdown Synology webstation

Shutdown Synology Web Station

7)

Now we can proceed on upgrading the Owncloud core files structure.

First we need to rename the existing Owncloud web folder to something else.

Select Code
1
mv /volume1/web/owncloud /volume1/web/old_owncloud

Then we proceed on loading the latest Owncloud version from Owncloud downloads as the new Owncloud web folder:

Select Code
1
2
3
4
wget --no-check-certificate https://download.owncloud.org/community/owncloud-9.1.0.tar.bz2 -O /tmp/owncloud-9.1.0.tar.bz2

cd /tmp
tar jxf owncloud-9.1.0.tar.bz2

Load Owncloud new version

Now you have loaded the version 9.1 and extracted the needed [Owncloud] folder into ‘/tmp’ folder. Next step is to move that folder into /volume1/web:

Select Code
1
mv /tmp/owncloud /volume1/web/

Now after copy, we need to again ensure that correct permissions are assigned to the ‘/volume1/web/owncloud’ folder:

Select Code
1
2
3
chown -R http:http /volume1/web/owncloud/
find /volume1/web/owncloud/ -type f -print0 | xargs -0 chmod 0777
find /volume1/web/owncloud/ -type d -print0 | xargs -0 chmod 0777

Move and change Owncloud permissions

8)

Now is the time to copy those preserved files from the old Owncloud directory back to the new updated Owncloud directory:

Based on my preserved file listing, this is how I do it:

Select Code
1
2
3
4
5
6
7
8
rm -R /volume1/web/owncloud/core/skeleton
cp -avr /volume1/web/old_owncloud/core/skeleton /volume1/web/owncloud/core/

rm /volume1/web/owncloud/config/config.php
cp -av /volume1/web/old_owncloud/config/config.php /volume1/web/owncloud/config/config.php

rm -R /volume1/web/owncloud/themes/
cp -avr /volume1/web/old_owncloud/themes /volume1/web/owncloud/

In similar manner you need to bring any special 3rd party apps you might have installed, from the old apps folder to the new apps folder.

At this point you also need to make the additional modifications (if any) you have made to the original Owncloud core files, like .htaccess or similar.

9)

Now after all above steps – you should have done all the preparations. Let’s re-start the Synology Web Service:

Enable Synology Web Station

10)

Now we need to start the upgrade process from command line with following commands:

Select Code
1
2
cd /volume1/web/owncloud
sudo -u http php56 occ upgrade

The upgrade operation takes a few minutes to a few hours, depending on the size of your installation. When it is finished you will see a success message, or an error message that will tell where it went wrong.

Owncloud manual occ upgrade

11)

If everything went smoothly, we can disable maintenance mode:

Select Code
1
2
cd /volume1/web/owncloud
sudo -u http php56 occ maintenance:mode --off

12)

I usually always right after the upgrade process, I run manually the occ command to scan all user files:

Select Code
1
2
cd /volume1/web/owncloud
sudo -u http php56 console.php files:scan --all

Manual Owncloud occ files scan

Now you can login for the first time to the upgraded Owncloud portal.

13)

Enjoy the 9.1 renewed default login screen background:

Renewed Owncloud 9.1 login screen

14)

After login the Owncloud web interface should open.

Kuva5

If you see the error “There were problems with the code integrity check” – this is most likely because Synology creates @eadir cache folders everywhere. Removing these manually from Owncloud folders will remove the error. In this job you might find this code useful:

Select Code
1
find . -name "@eaDir" -type d -print0 | xargs -0 rm -rf

And here is example on how to use it:

kuva_remove_eadirs
And you have now removed all ‘@eaDir’ folders from owncloud folders. And you should also be able to remove the error by Selecting ‘RESCAN’ on admin page of Owncloud.

kuva_remove_eadirs_check

15)

Enable and test functionality for any 3rd party apps you possible had installed.

16)

If everything seems to work correct and files seem okay – it is time to assign more strict permissions back:

Please regard the given script as example only – always validate security permissions for your needs as required – and review related documentation from Owncloud.org for version 9.

I use a script (.sh) file, with following contents:

#!/bin/bash

chown -R root:http /volume1/web/owncloud/

chown -R http:http /volume1/web/owncloud/apps/
chown -R http:http /volume1/web/owncloud/config/
chown -R http:http /volume1/web/owncloud/themes/

chown root:http /volume1/web/owncloud/.htaccess
chown root:http /volume1/owncloud/.htaccess

find /volume1/web/owncloud/ -type f -print0 | xargs -0 chmod 0640
find /volume1/owncloud/ -type f -print0 | xargs -0 chmod 0640
find /volume1/web/owncloud/ -type d -print0 | xargs -0 chmod 0750
find /volume1/owncloud/ -type d -print0 | xargs -0 chmod 0750

chmod 0644 /volume1/web/owncloud/.htaccess
chmod 0644 /volume1/owncloud/.htaccess

And I’m running it in SSH terminal like this (run it as root as it “can be done in DSM 6″ and from root folder in SSH terminal):

Setup permissions for use

 

Congratulations – you should have now successfully upgraded your Owncloud version!

Owncloud Version 9.1

Note: The renamed copy of the old Owncloud version should be removed away from web folder / assigned extremely strict permissions right after upgrade, and once you are confident the new updated Owncloud is working – you could delete the whole instance. After all, you still have the full & fresh back-up stored.

If this worked for you – please let me know by leaving a post / feedback below!

Thanks – and take care!

    Awesome – worked like a charm – very good.

    I found two minor things in your guide:

    Step 7
    => in the code exampls remove the $
    Step10
    => execute cd /volume1/web/owncloud first (as we are still in the /tmp on the console) or move it from step 11 to step 10

    • Juha KetolaJuha Ketola says:

      Hi Alex,

      Thanks for taking the first run, and thanks for the comments. I’ve updated based on your comments. Good points – thanks.

      Now we have 2 succesful updates made with this guide. Hopefully it will help others in their upgrade journeys!

      Take care!

      Br,
      Juha

    Work Fine!
    Thanks

  3. Alex says:

    Hi,

    maybe
    chown http:http /volume1/web/owncloud/.user.ini
    for the max upload size needs to be set again as well after upgrade, right?

    Cheers

    • Juha KetolaJuha Ketola says:

      Hi,

      Actually fully depending on how the user wants to configure the upload limits. It’s really up to the user….
      I’ve just brought up the thing if user wants to configure it through admin UI in Owncloud.

      /Juha

  4. Alex says:

    Hmh…if I change the upload size after all permissions have been applied again the .user.ini is written correctle but I get this error:

    Can’t write upload limit to /volume1/web/owncloud/.htaccess. Please check the file permissions

    If I do this:
    chmod 0644 /volume1/web/owncloud/.htaccess

    It works!
    So what do you think, should the write-right for http set for this file permanently? What about the .htaccess in the /volume/owncloud?

    Cheers
    Alex

    • Juha KetolaJuha Ketola says:

      Hi Alex,

      The permissions are always something that user should really focus and use some time to get the optimal setup for his/her case. That is why I have used here the recommendation from Owncloud documentation for setting Strong Directory Permissions – and not really dug deeper on that area.

    Hi Juha,

    first of all: thanks for your amazing tutorials! I successfully installed ownCloud 9 and upgraded to 9.1 with your guide.

    But coming now to my problem: I upgraded yesterday to v9.1.3. Unfortunately, my ownCloud logs show reoccurring PHP errors: “PHP Startup: No such handler: DBA_DEFAULT at Unknown#0”. I did not find anything about that anywhere else.
    Most interesting: Everything runs fine. All clients sync smoothly, the web interface runs correctly, … Do you have an idea where this error comes from? I could think of a problem with PHP communicating with MariaDB, but actually everything works fine.

    Cheers,
    Matthias

      Hi Juha & Matthias
      Great tutorial that helps a lot for installing and upgrading Owncloud on the Synology NAS.
      A BIG THANK YOU FOR THAT!
      I do get now the same message as Matthias. I saw somewhere that it occured when different PHP versions are installed and the wrong one is called about. But I do actually only have one installed…
      Any help?

    I am getting the following error.
    What is not correct ?

    sh-4.3# sudo -u http php56 occ upgrade
    ownCloud is not installed – only a limited number of commands are available

    [Symfony\Component\Console\Exception\CommandNotFoundException]
    Command “upgrade” is not defined.

    Thanks
    Sascha

    • Juha KetolaJuha Ketola says:

      Hi,

      Strange, If you follow the process exactly, it should/will work.
      Please doublecheck your file/folder permissions, then check that you copied the fies correctly.

      Perhaps reboot might also help If your system IS behaving strangely.
      I hope this helps. Take care.
