所有好的系统管理员的目标是避免成为硬件平均故障间隔时间的受害者，并找到一种方式来减轻磁盘故障的风险。
Technical events: "Hard disk failure", "Server started" or "Database 80% full" are examples of events that relate to the technical activity and configuration of the system.
技术事件：“硬盘故障”、“服务器启动”或者“数据库空间80%已满”这些都是与系统技术活动以及配置相关的事件的例子。
Since the data stored in VOD system is a kind of video stream, we can use an improved RAID5 technology to improve the efficiency of data reconstructing operation in disk failure.
由于在VOD系统中存放的数据都是一些视频流，我们分析了一种改进的RAID5技术——基于奇偶校验数据重构恢复的数据节点阵列RAID5。
If you're trying to determine why a server won't boot after a disk failure, the first thing I often do is to un-map or disconnect all disks from the server except for the root volume group.
如果想要判断一个服务器为何在磁盘故障后不能引导，我通常会做的第一件事情是从服务器(根卷组除外)，断开所有磁盘的映射和连接。
The journal is also useful for failure recovery: if the metadata server fails, its journal can be replayed to ensure that metadata is safely stored on disk.
这个日志对故障恢复也很有用：如果元数据服务器发生故障，它的日志就会被重放，保证元数据安全存储在磁盘上。
Problems such as corrupt data on the disk, power failures, and system crashes can all cause catastrophic failure of the resizing process.
磁盘上的不可靠数据、电源故障、以及系统崩溃的等问题可能会导致调整过程发生灾难性故障。
Persistent messages are written to disk and are therefore recoverable in the event of a system failure, but are correspondingly slow.
持久化的消息则会把消息写入磁盘，即便系统发生故障也可找回消息，但相应的处理速度较慢。
Nor does it protect you from situations where data has been lost due to a hardware or disk drive failure, data corruption, or other potential physical disasters.
它不能阻止由于硬件或磁盘驱动器故障、数据损坏或其它潜在物理灾难引起的数据丢失。
If the new cache copy is not written to disk before shutdown or failure of the cache, the update is lost, and this is very bad.
如果新的缓存副本没有在关机或缓存失败前写入磁盘，更新将丢失，这非常糟糕。
My reasoning is that MQIPT does not queue any data to disk so in the event of a channel failure, there is no data piling up in the DMZ.
理由就是MQIPT不会将任何数据排队到磁盘中，因而在出现通道故障时，DMZ 中不会出现数据堆积的现象。
If numerous large files are uploaded, the operating system could run out of disk space, resulting in a total failure.
如果上传无数大文件，操作系统会耗尽磁盘空间，导致整体故障。
In the event of a system failure, transaction log recovery can apply or undo only those transactions not written to disk at the time of the failure.
在系统失败时，事务日志可以应用或取消失败时没有写入磁盘的那些事务。
Upon failure of the primary site, perform the disk failover as shown in Listing 11 such that the data on the target site can be used to continue database processing at the target site.
若主站点故障，就执行清单11内所示的磁盘故障转换以便目标站点上的数据可被用来继续进行目标站点上的数据库处理。
The third failure group is required to solve disk quorum issues so that should either half of the storage go offline, disk quorum is satisfied, and the file system remains accessible.
第3个故障组是解决磁盘仲裁问题所必需的，以便如果存储的其中一半离线之后，磁盘仲裁能立即发挥作用且文件系统也能保持总可以被访问。
Server instances startup with the contents of their parent image. Upon server failure/restart the disk reverts back to the original image definition.
长久以来，服务器实例（server instantces）一直以父节点映像启动，当服务器发生故障或重启时，磁盘会恢复到原有映像。
In this mode, the Shared volume groups are accessible by multiple PowerHA nodes, which results in faster failover (disk takeover) in the event of a node failure.
在这种模式下，多个Power ha节点都可以访问共享卷组，这会加快发生节点故障时的故障转移(磁盘接管)。
Since these technologies do only utilize one copy of the data, the disk would still be a single point of failure.
由于这些技术只使用一份数据副本，所以磁盘仍然会出现单点故障。
File system content is usually replicated across the cell so that failure of one hard disk would not impair working at the OpenAFS client.
文件系统内容通常都是跨cell复制，以便一个硬盘的失效不会损害OpenAFS客户机上的运行。
Low cycle multiaxial fatigue failure is the main failure mode of aeroengine compressor disk.
低循环多轴疲劳失效是航空发动机低压压气机轮盘的主要失效形式。
Ideally, the locations of the members should be on separate disks so that the failure of one disk does not cause the loss of the entire online redo log.
理论上说，日志文件组的成员的存放位置应该放在磁盘上的不同位置，这样即使一个磁盘损坏也不会导致整个在线重做日志文件丢失。
A media failure is a physical problem with a disk that causes a failure of a read from or write to a disk file that is required to run the database.
介质故障是磁盘，导致读失败或写入运行数据库所需磁盘文件失败的一个物理问题。
A head crash in a fixed hard disk generally destroys the data, whereas the failure of a tape drive or optical disk drive often leaves the data cartridge unharmed.
对于固定的硬盘，磁头撞击通常会破坏数据，然而磁带或光盘驱动器的错误通常对数据盘碟是无害的。
