Hello guys, i have big problem as it seems i have broken my multiserver setup. I had problem with something which looked as not correctly updated databases as in this thread https://www.howtoforge.com/communit...ith-slave-server-databases.79569/#post-377248 Today i did following - backed up original databases - deleted databases - imported only dbispconfig structure from clean install of ISPConfig 3.1.13 - imported only data from my existing install into clean databases it went smooth, except client templates, i was gettign error #1054 - Unknown column 'default_mailserver' in 'field list' . It was no problem i imported it without templates and re-created them manually with same template numbers. When i enabled cron there came problem, i was getting errors 17.10.2018-21:18 - WARNING - There is already a lockfile set, but no process running with this pid (6450). Continuing. Unable to load the server configuration from [email protected] So, i stoped cron, then rm -f /usr/local/ispconfig/server/temp/.ispconfig_lock run manually /usr/local/ispconfig/server/server.sh Then i'm getting again "Unable to load the server configuration from [email protected]" (and also on other slave servers mail and db) All logins in config files are correct i can log into dbispconfig as root , also as ispconfig amd also ispconfig remote db user to main server AND HERE COMES THE MAIN PROBLEM when i load the backup of original databases back, i'm in same exact situation "Unable to load the server configuration from database.root" on all slave servers Can you help me please. What can i do to get syncing back ? delete dalalog somehow ? force upgrade ? Regards R.H.
