无法使用 ROW_FORMAT=COMPRESSED 创建表

Question

我正在尝试在 Docker 容器中的 MariaDB 10.4.11-MariaDB-1:10.4.11+maria~bionic 上安装 Nextcloud (mariadb:latest sha256:2f11cf2ec18988aec8346a5cf528d69ac3f0f4fc02af79ba28f4fd47b7778d6f)。

安装程序所做的第一件事是尝试ROW_FORMAT=COMPRESSED在 DDL 中创建一个表，这会产生错误 140“错误的创建选项”。

如果我省略 row_format 参数，则会创建表，但使用 DYNAMIC row_format。

这里发生了什么？是否ROW_FORMAT=COMPRESSED在某个时候被删除了，或者正在拉取的 MariaDB docker 版本是否未使用它进行编译？

如果不修改 Nextcloud 的 SQL DDL，我能在这里做什么？

Edit:

最后可以添加有关我的系统的更多信息，如下：

首先是我的my.cnf

[mysqld]
innodb_large_prefix=on
innodb_file_per_table=on
innodb_doublewrite=off
innodb_page_size=64k
innodb_file_format=barracuda

innodb_compression_algorithm=lz4
innodb_compression_default=ON

这会导致启动包含以下行：

由于我必须更改创建表 DDL 才能运行，因此这是实际创建的此类表的示例：

CREATE TABLE `oc_users` (
  `uid` varchar(64) COLLATE utf8mb4_bin NOT NULL DEFAULT '',
  `displayname` varchar(64) COLLATE utf8mb4_bin DEFAULT NULL,
  `password` varchar(255) COLLATE utf8mb4_bin NOT NULL DEFAULT '',
  `uid_lower` varchar(64) COLLATE utf8mb4_bin DEFAULT '',
  PRIMARY KEY (`uid`),
  KEY `user_uid_lower` (`uid_lower`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_bin `PAGE_COMPRESSED`='ON' 

请注意，onlyPAGE_COMPRESSED是一个有效的选项，ROW_FORMAT=COMPRESSED无论如何该选项都会失败。

我运行的系统有 8 GB RAM，其中 MariaDB 使用了大约 170 MB。

如果其他人偶然发现这个线程（像我一样）寻找解决方案

4047 InnoDB refuses to write tables with ROW_FORMAT=COMPRESSED or KEY_BLOCK_SIZE

或者来自 nextcloud 的 mariadb 的类似错误，每当 nextcloud 尝试写入数据库时​​就会发生：对我来说重要的线索是，这个错误可能与 utf8 编码问题有关。请参阅此处获取 nextcloud 文档：

https://docs.nextcloud.com/server/21/admin_manual/configuration_database/mysql_4byte_support.html

长话短说：

https://help.nextcloud.com/t/update-to-next-cloud-21-0-2-has-get-an-error/117028/7对我来说的解决方案 是：

php occ config:system:set mysql.utf8mb4 --type boolean --value="false"

其次是

php occ maintenance:repair --include-expensive

这将修复所有表，以便再次可以写入它们。
