摘要： Data-storage volumes, such as a file system on a storage system, may utilize a particular operating system format. Converting a data-storage volume to a different format may be desirable at times. However, this can be time consuming and resource intensive if data needs to be copied. Accordingly, substantially copying-free, in-place conversion of a data-storage volume from a first format to a second format is provided herein. In one embodiment, a data-storage volume may be converted from a first format to a second format while the data-storage volume is mounted and/or without copying data within the data-storage volume to a separate data-storage volume. Before conversion, features associated with the first format and the second format may be compared to detect incompatibilities that may result from conversion. During conversion, access to the data-storage volume may be blocked. Upon successful conversion, various post conversion operations may be performed.
摘要翻译：数据存储卷（例如存储系统上的文件系统）可以利用特定的操作系统格式。有时可能需要将数据存储卷转换为不同的格式。但是，如果需要复制数据，这可能会耗费时间和资源。因此，本文提供了数据存储卷从第一格式到第二格式的基本上无复制的原位转换。在一个实施例中，数据存储卷可以在数据存储卷被安装和/或不将数据存储卷内的数据复制到单独的数据存储卷的同时从第一格式转换为第二格式。在转换之前，可以比较与第一格式和第二格式相关联的特征，以检测可能由转换产生的不兼容性。在转换期间，可能会阻止对数据存储卷的访问。成功转换后，可以执行各种后转换操作。

摘要： On or more techniques and/or systems are provided for rapidly resuming processing of client requests after a system failure event. Accordingly, during a boot-up process, a storage system, upon detecting a system failure event of the storage system, conditions its system memory to reflect a state of the system memory at a time of the failure by processing client requests or commands stored in a non-volatile operations log. The storage system can resume processing client requests after processing the operations in the nonvolatile operations log and prior to flushing data to storage devices.
摘要翻译：提供或更多的技术和/或系统用于在系统故障事件之后快速恢复客户端请求的处理。因此，在启动过程中，存储系统在检测到存储系统的系统故障事件时，通过处理存储在存储系统中的客户端请求或命令来调节其系统存储器以在故障发生时反映系统存储器的状态非易失性操作日志。在处理非易失性操作日志中的操作之前，以及在将数据刷新到存储设备之前，存储系统可以恢复处理客户端请求。

摘要： A method and apparatus for delaying the process of freeing data blocks during the processing of a non-volatile transactions log are disclosed. Accordingly, after a system failure, when a storage system is replaying transactions in a non-volatile transactions log, the storage system flushes the data generated from the transactions to disk storage without freeing and data blocks which, as a result of processing the transactions log, are no longer storing data that is part of the active file system. Consequently, the replay of the transactions log takes less time, and the storage system is brought online more quickly.
摘要翻译：公开了一种用于在处理非易失性事务日志期间延迟释放数据块的过程的方法和装置。因此，在系统故障之后，当存储系统在非易失性事务日志中重播事务时，存储系统将从事务生成的数据刷新到磁盘存储而不释放数据块，作为处理事务日志的结果，不再存储作为活动文件系统一部分的数据。因此，事务日志的重放需要更少的时间，并且存储系统更快地上线。

摘要： A file array storage architecture comprises a file system that is distributed across a data processing platform consisting of a host computer coupled to an adapter over a high-speed, low latency interface and an input/output subsystem that is located entirely on the adapter. The distributed nature of the architecture enables implementation of the file system in accordance with a modified client-server computing model; that is, the architecture includes a client file system executing on the host computer and a server file system executing on the adapter.

摘要： An apparatus and method for rapidly resuming the processing of client requests after a system failure event are disclosed. Accordingly, a surviving storage system, upon detecting a system failure event at a partner storage system, executes a takeover routine and conditions its system memory to reflect the state of the system memory of the failed storage system by processing client requests or commands stored in an operations log mirror. Then, the storage system converts the unused portion of the log mirror for use as an operations log, and resumes processing client requests prior to flushing any data to storage devices.

摘要： Servicing an access request using a plurality of replicas of data includes determining which of the replicas are available and selecting one of the replicas for servicing the access request based on which of the replicas are available. At least one other replica is indicated as not available in response to receiving a monitoring message indicating that the at least one other replica is subject to degraded performance. The monitoring messages are independent of the access request. The monitoring messages may be SNMP messages. Servicing an access request using a plurality of replicas of data may also include determining if each of the SNMP messages affects the availability of the replicas. The replicas may be selected in round robin fashion or randomly.

However, this can be time consuming and resource intensive if data needs to be copied. Accordingly, substantially copying-free, in-place conversion of a data-storage volume from a first format to a second format is provided herein. In one embodiment, it is determined whether the volume can be converted, for example, by comparing compatibility of features between the first and second formats. A desired feature list is retrieved and respective features are checked for compatibility. Access to the volume is blocked during the conversion, and the volume is converted if the features are found to be compatible. If the conversion is successful, post conversion operations are performed, including unblocking the volume and notifying clients that the volume is available for access.
