Question

在Ubuntu Trusty Server 64bit上：

我使用不同的datadir工作的MariaDB 10.1

datadir=/mnt/SRVDATA/var/lib/mysql

昨天我从

获得了更新10.1.13-MariaDB-1~可信任

deb http://mirror.netcologne.de/mariadb/repo/10.1/ubuntu trusty main

MariaDB将不再启动。

我重命名了/ etc / mysql，/ usr / lib / mysql和/ var / lib / mysql，我重新安装了MariaDB Server和Client。我做了一个dpkg-reconfigure，我在/ var / lib / mysql中得到了一个新的pristine数据库。有了它，我可以启动MariaDB。

我将/ var / lib / mysql再次复制到/ mnt / SRVDATA / var / lib / mysql并拥有所有权限，我将my.cnf更改为指向datadir为/ mnt / SRVDATA / var / lib / mysql但是MariaDB赢了'开始。

Apparmor已关闭，它的配置文件已被拆解。

syslog中的错误：

非常感谢任何提示！

Answer 1

在#maria的FreeNode上与Montywi进行了很好的聊天后发现，这是版本10.1.13中引入的新bug。

它涉及配置：

innodb_flush_method=O_DIRECT

与块大小＆lt;＆gt;的文件系统上的datadir结合使用512（我的是在RAID上）

现在的解决方法是：

innodb_flush_method=O_DSYNC

该错误现在已经修复，很快就会在10.1.14版本中提供，因此Montywi。

谢谢大家！
