Description:

Hello,

I'm in the progress of migrating from a debian 11 with tomcat to a debian 12 with jetty and I'm struggling with the restore. Or better I was struggling. So this here is more a question than a bug-report. I wanted to write this into the forum, but I'm getting no mails from the xwiki-forum-server for password reset or login-link

After restoring (DB+dataDirectory+config) I got many errors,.. in the log file like this one:

There are all versions since version my xwiki-install

 

 

My solution is by preparing the data from the backup with the following lines:

 

7zz x  xwikiData.7z.001 -oxwikiData -y
rm -rf xwikiData/xwiki/data/cache/
rm -rf xwikiData/xwiki/data/store/solr/find xwikiData/xwiki/data/extension/repository -type d -name "13%2E*" -exec rm -rf {} 2> /dev/null \;
find xwikiData/xwiki/data/extension/repository -type d -name "13%2E*" -exec rm -rf {} 2> /dev/null \;
find xwikiData/xwiki/data/extension/repository -type d -name "14%2E*" -exec rm -rf {} 2> /dev/null \;
find xwikiData/xwiki/data/extension/repository -type d -name "15%2E*" -exec rm -rf {} 2> /dev/null \;
find xwikiData/xwiki/data/extension/repository -type d -name "16%2E1*" -exec rm -rf {} 2> /dev/null \;
find xwikiData/xwiki/data/extension/repository -type d -name "16%2E2*" -exec rm -rf {} 2> /dev/null \;
find xwikiData/xwiki/data/extension/repository -type d -name "16%2E3*" -exec rm -rf {} 2> /dev/null \;
find xwikiData/xwiki/data/extension/repository -type d -name "16%2E4*" -exec rm -rf {} 2> /dev/null \;
find xwikiData/xwiki/data/extension/repository -type d -name "16%2E5*" -exec rm -rf {} 2> /dev/null \;
find xwikiData/xwiki/data/extension/repository -type d -name "16%2E6*" -exec rm -rf {} 2> /dev/null \;
find xwikiData/xwiki/data/extension/repository -type d -name "16%2E7*" -exec rm -rf {} 2> /dev/null \;

 

So I remove all old extensions but the latest 16.9.0
A start of xwiki results then in a error and warning free starting.

(deleting the solr/find directory removed one other error source which I cannot find anymore in the log files)

 

I have a working solution, but why did I have to do this?

 

I tried to follow https://www.xwiki.org/xwiki/bin/view/Documentation/AdminGuide/Backup but the restore-part there is not very clear for me. 
Also if the ROOT.tar.gz in the example backup-script there is my /usr/lib/xwiki where the WEB-INF is located. But I found out, that there is noting, which I have to restore from /usr/lib/xwiki for a working xwiki.

My complete restore progress of my tomcat backup:

  • apt install xwiki-xjetty-mariadb
  • stop xwiki
  • restore sql from main-wiki and subwikis
  • replace the /var/lib/xwiki/data/ with the one from the backup
    • without cache and solr/find
    • without old extensions
  • start xwiki

 

All config files are unchanged except plantuml-server-url, LDAP and two mods for a working nginx redirect.

Description: Hello,

I'm in the progress of migrating from a debian 11 with *tomcat* to a debian 12 with *jetty* and I'm struggling with the restore. Or better I was struggling. So this here is more a question than a bug-report. I wanted to write this into the forum, but I'm getting no mails from the xwiki-forum-server for password reset or login-link

After restoring (DB+dataDirectory+config) I got many warnings and errors ,.. and funny behaviour in the log file like general. See this one example :

 Here the content of this directory on the old server for this extension I included from the log above (the same for the other extensions)

There are all versions since version my xwiki-install

 

  

 My solution is by preparing the data from the backup with the following lines:
 
 {code:java}
7zz x  xwikiData.7z.001 -oxwikiData -y
rm -rf xwikiData/xwiki/data/cache/
rm -rf xwikiData/xwiki/data/store/solr/
find xwikiData/xwiki/data/extension/repository -type d -name "13%2E*" -exec rm -rf {} 2> /dev/null \;
find xwikiData/xwiki/data/extension/repository -type d -name "13%2E*" -exec rm -rf {} 2> /dev/null \;
find xwikiData/xwiki/data/extension/repository -type d -name "14%2E*" -exec rm -rf {} 2> /dev/null \;
find xwikiData/xwiki/data/extension/repository -type d -name "15%2E*" -exec rm -rf {} 2> /dev/null \;
find xwikiData/xwiki/data/extension/repository -type d -name "16%2E1*" -exec rm -rf {} 2> /dev/null \;
find xwikiData/xwiki/data/extension/repository -type d -name "16%2E2*" -exec rm -rf {} 2> /dev/null \;
find xwikiData/xwiki/data/extension/repository -type d -name "16%2E3*" -exec rm -rf {} 2> /dev/null \;
find xwikiData/xwiki/data/extension/repository -type d -name "16%2E4*" -exec rm -rf {} 2> /dev/null \;
find xwikiData/xwiki/data/extension/repository -type d -name "16%2E5*" -exec rm -rf {} 2> /dev/null \;
find xwikiData/xwiki/data/extension/repository -type d -name "16%2E6*" -exec rm -rf {} 2> /dev/null \;
find xwikiData/xwiki/data/extension/repository -type d -name "16%2E7*" -exec rm -rf {} 2> /dev/null \;
{code}
 

So I remove removed all old extensions but the latest 16.9.0 (from the new server) :
{code:java}
l /var/lib/xwiki/data/extension/repository/org%2Exwiki%2Eplatform%3Axwiki-platform-image-lightbox-ui/
total 36
drwxr-x---   3 xwiki xwiki  4096 Nov 15 11:34 .
drwxr-x--- 264 xwiki xwiki 28672 Oct 21 11:34 ..
drwxr-x---   2 xwiki xwiki  4096 Nov 12 08:29 16%2E9%2E0 {code}
 A start of xwiki results then in a error and warning free starting.

(deleting the solr /find directory removed one other error /warning source which I cannot find anymore in the log files)

 

I have a working solution, but why did I have to do this? And did I something which will bring me into troubles some day?

 

I tried to follow [https://www.xwiki.org/xwiki/bin/view/Documentation/AdminGuide/Backup] but the restore-part there is not very clear for me. 
Also if the ROOT.tar.gz in the example backup-script there is my /usr/lib/xwiki where the WEB-INF is located. But I found out, that there is noting nothing , which I have to restore from /usr/lib/xwiki for a working xwiki.

My complete restore progress of my tomcat backup:
* apt install xwiki-xjetty-mariadb
* stop xwiki
* restore sql from main-wiki and subwikis
* replace the /var/lib/xwiki/data/ with the one from the backup
** without cache and solr /find
** without old extensions
* start xwiki

 

All config files are unchanged except plantuml-server-url, LDAP and two mods for a working nginx redirect.
