Abstract: A method is used in managing concurrent I/Os in file systems. A first and second I/O requests are received. The first I/O request is directed to a first portion of a file and the second I/O request is directed to a second portion of the file. A first range lock for the first portion is obtained and a second range lock for the second portion is obtained. The first and second I/O requests are performed concurrently. The second I/O request starts performing I/O on the second portion of the file before the first I/O request finish performing I/O on the first portion of the file.

Abstract: Directory attributes are provided so that the time for creating an incremental backup of a file system by a scan of the file system tree is proportional generally to the number of files that change between backups instead of the number of files in the file system. A tree modification attribute indicates whether or not any file in a directory tree has changed since the last backup. If no file has changed in the directory tree, then the entire tree is skipped during the scan for changed files. In addition, a list is compiled of the files in the directory that represent branches having at least one changed file, so that the list is scanned instead of the directory entries. When a file is changed for the first time since the last backup, the file is queued so that the directory attributes are updated in a background process.

Abstract translation: 提供目录属性，以便通过文件系统树的扫描来创建文件系统的增量备份的时间通常与备份之间而不是文件系统中的文件数量的文件数量成比例。 树修改属性指示自上次备份以来目录树中的任何文件是否已更改。 如果目录树中没有文件已更改，则在扫描更改的文件期间将跳过整个树。 另外，编译目录中表示具有至少一个已更改文件的分支的文件的列表，以便扫描列表而不是目录条目。 当文件自上次备份以来首次更改文件时，文件将排队，以便在后台进程中更新目录属性。

Abstract: Accordingly a method and interface allows an attribute data base used by an Information Manager to be quickly populated and accurately maintained. A single Bulk Attribute Retrieval Request triggers the primary storage device to collect object attribute information. The method allows for selective collection of objects and attributes by providing filters and attribute lists in the Requests. The Request may be used to provide an incremental scan with appropriate time stamp filtering. In addition, the size of the results can be controlled by the IM by eliminating attributes that are not of interest to the IM. The Request is advantageously issued over a FileMover interface, which is an HTTP connection, and encoded in XML, allowing the IM to easily customize the Request as desired.

Abstract translation: 因此，方法和接口允许快速填充并准确地维护信息管理器使用的属性数据库。 单个批量属性检索请求触发主存储设备收集对象属性信息。 该方法允许通过在请求中提供过滤器和属性列表来选择性地收集对象和属性。 请求可用于通过适当的时间戳过滤提供增量扫描。 此外，结果的大小可以通过IM消除IM不感兴趣的属性来控制。 该请求有利地通过FileMover接口发布，该接口是HTTP连接，并以XML编码，允许IM根据需要容易地定制请求。
