一种目录迁移方法和元数据负载均衡方法
摘要：
本申请提供了一种目录迁移方法，包括：应用于分布式文件系统中元数据的目录迁移，其特征在于，该方法包括：获取待迁移目录包含的当前文件数；当所述待迁移目录包含的当前文件数大于设定阈值时，将所述待迁移目录划分为多个子目录，每一个所述子目录包括的当前文件数小于或等于所述设定阈值；将各个所述子目录向目标节点迁移，直到所述待迁移目录包含的当前文件数小于或等于所述设定阈值时，将所述待迁移目录迁移到所述目标节点。
摘要（英）：

The invention provides a directory migration method. The method is applied to the directory migration of metadata in a distributed file system. The method is characterized by comprising the steps of obtaining a current file quantity comprised in a to-be-migrated directory; when the current file quantity comprised in the to-be-migrated directory is greater than a set threshold, dividing the to-be-migrated directory into multiple sub-directories, wherein the current file quantity comprised in each sub-directory is smaller than or equal to the set threshold; and migrating each sub-directory to atarget node, and until the current file quantity comprised in the to-be-migrated directory is smaller than or equal to the set threshold, migrating the to-be-migrated directory to the target node.
