May it help others: I restored an Appdata backup and edited the custom.cnf file by adding the entry „innodb_log_files_in_group = /config/logs“ which created two new log containers and enabled the start of mysqld. The original files were corrupted due to my cache drive ran out of space caused by a vm...

I managed to get into the webinterface by deleting the .../www/owncloud folder. But when I try to use the internal db as you describe I get the same `no such file or directory’ error, only in the webinterface. How can I really start over from scratch? Do I need a new docker.img? Since you obviously prepared an empty database to start out of the box and deleting appdata/ownCloud doesn‘t touch it: where is it located?

So the database doesn‘t live inside the container, but somewhere more globally (you implied otherwise on page 1 of this post)? And perhaps other installations could make use of the same database and potentially mess it up? So: how do I set it up „properly“? Did I miss a guide, tutorial or something?

@dlandonRe-Installation including removing the owncloud folder in appdata doesn‘t re-create the database?

@dlandon Your OwnCloud docker ran fine for about a year. Other than auto-updates I had no reason to ever change something, but a few days ago my calendars stopped to synchronize. Checking the web interface for reasons I found this instead: Exception occurred while logging exception: Failed to connect to the database: An exception occured in driver: SQLSTATE[HY000] [2002] No such file or directory #0 /config/www/owncloud/lib/composer/doctrine/dbal/lib/Doctrine/DBAL/Connection.php(429): OC\DB\Connection->connect() #1 /config/www/owncloud/lib/composer/doctrine/dbal/lib/Doctrine/DBAL/Connection.php(389): Doctrine\DBAL\Connection->getDatabasePlatformVersion() #2 /config/www/owncloud/lib/composer/doctrine/dbal/lib/Doctrine/DBAL/Connection.php(328): Doctrine\DBAL\Connection->detectDatabasePlatform() #3 /config/www/owncloud/lib/composer/doctrine/dbal/lib/Doctrine/DBAL/Connection.php(623): Doctrine\DBAL\Connection->getDatabasePlatform() #4 /config/www/owncloud/lib/private/DB/Connection.php(145): Doctrine\DBAL\Connection->setTransactionIsolation(2) #5 /config/www/owncloud/lib/composer/doctrine/dbal/lib/Doctrine/DBAL/DriverManager.php(172): OC\DB\Connection->__construct(Array, Object(Doctrine\DBAL\Driver\PDOMySql\Driver), Object(Doctrine\DBAL\Configuration), Object(Doctrine\Common\EventManager)) #6 /config/www/owncloud/lib/private/DB/ConnectionFactory.php(145): Doctrine\DBAL\DriverManager::getConnection(Array, Object(Doctrine\DBAL\Configuration), Object(Doctrine\Common\EventManager)) #7 /config/www/owncloud/lib/private/Server.php(493): OC\DB\ConnectionFactory->getConnection('mysql', Array) #8 /config/www/owncloud/lib/composer/pimple/pimple/src/Pimple/Container.php(113): OC\Server->OC\{closure}(Object(OC\Server)) #9 /config/www/owncloud/lib/private/AppFramework/Utility/SimpleContainer.php(111): Pimple\Container->offsetGet('DatabaseConnect...') #10 /config/www/owncloud/lib/private/ServerContainer.php(87): OC\AppFramework\Utility\SimpleContainer->query('DatabaseConnect...') #11 /config/www/owncloud/lib/private/Server.php(1160): OC\ServerContainer->query('DatabaseConnect...') #12 /config/www/owncloud/lib/private/Server.php(370): OC\Server->getDatabaseConnection() #13 /config/www/owncloud/lib/composer/pimple/pimple/src/Pimple/Container.php(113): OC\Server->OC\{closure}(Object(OC\Server)) #14 /config/www/owncloud/lib/private/AppFramework/Utility/SimpleContainer.php(111): Pimple\Container->offsetGet('AppConfig') #15 /config/www/owncloud/lib/private/ServerContainer.php(87): OC\AppFramework\Utility\SimpleContainer->query('AppConfig') #16 /config/www/owncloud/lib/private/Server.php(1089): OC\ServerContainer->query('AppConfig') #17 /config/www/owncloud/lib/private/Server.php(547): OC\Server->getAppConfig() #18 /config/www/owncloud/lib/composer/pimple/pimple/src/Pimple/Container.php(113): OC\Server->OC\{closure}(Object(OC\Server)) #19 /config/www/owncloud/lib/private/AppFramework/Utility/SimpleContainer.php(111): Pimple\Container->offsetGet('AppManager') #20 /config/www/owncloud/lib/private/ServerContainer.php(87): OC\AppFramework\Utility\SimpleContainer->query('AppManager') #21 /config/www/owncloud/lib/private/Server.php(1359): OC\ServerContainer->query('AppManager') #22 /config/www/owncloud/lib/private/legacy/app.php(346): OC\Server->getAppManager() #23 /config/www/owncloud/lib/private/legacy/app.php(110): OC_App::getEnabledApps() #24 /config/www/owncloud/lib/base.php(579): OC_App::loadApps(Array) #25 /config/www/owncloud/lib/base.php(998): OC::init() #26 /config/www/owncloud/index.php(54): require_once('/config/www/own...') #27 {main} Looks like something very much internal to the docker. I tried (after backing up appdata) a forced update, to remove the container and cleanly reinstall it, changing the additional options, the network interface (since intermediately I had no access to the web GUI at all) - all without success. Any pointers, please?!

Unraid version used is 6.6.3 stable. No fancy stuff installed, no crappy hardware, configuration all-straight-forward. In both cases there was no connection loss logged. I'm not willing to fiddle around with this risking my data. A fundamental point of dockerization is to isolate its processes from the host system. So either the docker is faulty or the system is unstable. Since everything else works fine, I have my eyes on the docker.

Statement: I cannot recommend using this docker. Why? It crashed Unraid twice with a simple 1-folder 60GByte photo backup (no special gimmicks used) onto a local SMB share. What happened? The backup process started and after a few minutes (like 10-12) the web interface died "lost server connection... retry in...". After that I was unable to stop the docker, therefore I could not stop the array and was in the end forced to cold reboot+parity check... What I tried: to avoid cold reboot I followed the unraid-wiki instructions (https://wiki.lime-technology.com/Console#To_cleanly_Stop_the_array_from_the_command_line) of course I followed the video tutorial and read about duplicati on Unraid. Searching for a stable and working alternative now, pretty disapointed about Unraid for not having a "favored/built-in/well-proven/well-maintained" solution for a simple local backup in place (no cloud). A little more disappointed that a docker running on Unraid can easily tear down the whole system until complete unresponsiveness. This is NOT what I would call a "stable" system.

Had a similar problem and have it again after each Plugin update (quite annoying, actually): svnadmin: error while loading shared libraries: libicui18n.so.56: cannot open shared object file: No such file or directory I solve this by doing a manual installation of the following package: icu4c-56.1-x86_64-2.txz Download, grab a terminal, cd to the file and execute: upgradepkg --install-new icu4c-56.1-x86_64-2.txz
