目前，在一些大规模分布式应用环境中，磁盘数量巨大并且磁盘比较分散，对磁盘的维护比较困难。例如，在内容分发网络中，当磁盘出现故障时，通常是等到磁盘掉线或严重影响业务/服务质量后，才会安排人员替换出现故障的磁盘。这样处理的弊端在于：磁盘出现故障时处理效率较低，此外，磁盘坏道是磁盘常见的故障，如果用新的磁盘替换只有少量坏道的磁盘，会造成较大的资源浪费。
发明内容
本申请的目的在于提供一种磁盘坏道的处理方法、装置及计算机存储介质，能够在节省磁盘资源的情况下，提高故障磁盘的处理效率。
为实现上述目的，本申请一方面提供一种磁盘坏道的处理方法，所述方法包括：获取待处理的目标磁盘，并检测所述目标磁盘中的坏道数据；合并所述坏道数据表征的坏道区域，以得到所述目标磁盘中除所述坏道区域以外的可用区域；根据检测结果，判断所述目标磁盘是否可用，若可用，基于所述可用区域重新构建所述目标磁盘的存储空间，并为重新构建的所述存储空间设置接入参数。
为实现上述目的，本申请另一方面还提供一种磁盘坏道的处理装置，所 述装置包括：磁盘检测单元，用于获取待处理的目标磁盘，并检测所述目标磁盘中的坏道数据；坏道隔离单元，用于合并所述坏道数据表征的坏道区域，以得到所述目标磁盘中除所述坏道区域以外的可用区域；空间重构单元，用于根据检测结果，判断所述目标磁盘是否可用，若可用，基于所述可用区域重新构建所述目标磁盘的存储空间，并为重新构建的所述存储空间设置接入参数。
为实现上述目的，本申请另一方面还提供一种磁盘坏道的处理装置，所述装置包括存储器和处理器，所述存储器用于存储计算机程序，所述计算机程序被所述处理器执行时，执行上述的方法。
为实现上述目的，本申请另一方面还提供一种计算机存储介质，所述计算机存储介质用于存储计算机程序，所述计算机程序被处理器执行时，执行上述的方法。
由上可见，本申请提供的技术方案中，可以自动识别目标磁盘是否需要进行坏道测试。具体地，可以定期获取目标磁盘的健康状态信息，并针对健康状态信息进行分析，从而确定目标磁盘是否需要进行坏道测试。当需要进行坏道测试时，可以将坏道数据表征的坏道区域进行合并，合并后的坏道区域在目标磁盘中可以被隔离，从而得到剔除坏道区域的可用区域。由于坏道区域的存在，可用区域在目标磁盘中可能会呈现离散的分布情况，此时，为了正常使用目标磁盘中的可用区域，可以基于所述可用区域重新构建所述目标磁盘的存储空间，并为重新构建的所述存储空间设置接入参数。具体地，可以按照所述可用区域，将所述目标磁盘划分为多个分区，并将所述多个分区合并为一个卷。在对合并后的卷进行格式化之后，可以将格式化后的卷的卷标和挂载点沿用目标磁盘原先的卷标和挂载点，从而完成对故障磁盘的处理过程。处理之后的磁盘，由于坏道区域被隔离开，从而不会影响正常区域的使用。由此可见，本申请提供的技术方案，在出现少量坏道时，不需要将磁盘整体替换，而是可以采用坏道隔离的方式，充分利用可用区域，因此能够在节省磁盘资源的情况下， 提高故障磁盘的处理效率。

具体实施例
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施例作进一步地详细描述。
实施例一
本申请提供一种磁盘坏道的处理方法，请参阅图1和图2，所述方法可以包括以下步骤。
S1：获取待处理的目标磁盘，并检测所述目标磁盘中的坏道数据。
在本实施例中，可以定期执行磁盘状态监控脚本，该脚本在执行时，可以获取目标磁盘的健康状态信息。在实际应用中，所述目标磁盘的健康状态信息可以包括所述目标磁盘的自检信息、所述目标磁盘所处操作系统的日志信息以及所述目标磁盘的输入输出负载信息中的至少一种。其中，所述自检信息可以是目标磁盘的S.M.A.R.T(Self-Monitoring Analysis and Reporting  Technology，自我监测、分析及报告技术)信息，S.M.A.R.T信息可以保留在硬盘的系统保留区(service area)内。S.M.A.R.T标准中可以采用二进制代码作为S.M.A.R.T的基本指令，并规定写入标准的寄存器中，形成特定的S.M.A.R.T信息表，以供正常检测和运行。S.M.A.R.T指令可以分为主指令(Command)和次指令(Subcommands)。主指令主要提供设备是否支持S.M.A.R.T或忽略某一次指令特征的信息。而次指令则提供支持S.M.A.R.T设备的检测信息。在S.M.A.R.T信息中，可以显示目标硬盘是否失败(FAIL)，还可以显示目标磁盘在运行时是否出现了错误，并且可以根据出现错误的数量，判断该目标磁盘是否出现了大量错误(错误数量在200以上)。所述日志信息可以指操作系统的message信息，该信息可以表明目标磁盘是否有读写错误，以及是否有文件系统错误。所述输入输出负载信息则可以表征目标磁盘是否处于高负载的运行状态下。
在本实施例中，可以预先设定目标磁盘可能存在的运行状态，然后基于所述目标磁盘的健康状态信息，可以分别确定各个所述运行状态对应的判定结果，以得到所述目标磁盘的判定结果组合。例如，请参阅表1，表1中列出了多个运行状态，并且在各个运行状态下，例举了可能的判定结果，每一行均可以作为一个判定结果组合。

Figure PCTCN2018091579-appb-000001
在本实施例中，在得到目标磁盘实际的判定结果组合时，可以调用所述判定结果组合对应的预设处理策略，所述预设处理策略可以用于表征所述目标磁盘是否需要进行坏道测试。如表1所示，所述预设处理策略可以是“处理动作”这一栏的信息，根据不同的判定结果组合，可以对应不同的处理动作。
S3：合并所述坏道数据表征的坏道区域，以得到所述目标磁盘中除所述坏道区域以外的可用区域。
在本实施例中，当判断结果表示需要对目标磁盘进行坏道测试时，可以中止所述目标磁盘中的业务或者中止所述目标磁盘所处服务器中的业务。例如，可以将该目标磁盘从服务器中暂时剔除，或者直接将该目标磁盘所处的服务器停机。这样，可以在对目标磁盘进行坏道测试时，不妨碍正常的业务执行过程。
在本实施例中，在对目标磁盘进行坏道测试时，首先可以对所述目标磁盘中的逻辑坏道进行修复，最终，可以将无法修复的坏道对应的坏道数据保存至指定文件中。所述指定文件可以是在操作系统中预先设置的文件，后续对坏道数据进行分析时，可以通过该指定文件的访问路径，读取其中的坏道数据。
在本实施例中，当完成坏道测试的过程后，可以针对所述指定文件中的坏道数据进行分析。在实际应用中，所述坏道数据可以是一个一维的非负整数的数组。该数组中可以包含多个元素，其中，每个元素可以代表一个容量为4KB的坏道，同时，该元素的元素值可以表征坏道在目标磁盘上所处的位置。例如，元素值N(从0开始的整数)可以代表所述目标磁盘中的第N+1个容量为4KB的区域。
在本实施例中，可以采用尽可能小的区域将坏道所在的区域覆盖，并将覆盖坏道的区域从目标磁盘中隔离，从而得到目标磁盘中可以正常使用的可用区域。具体地，可以预先将所述目标磁盘的存储空间划分为指定数量的子区域。例如，可以将目标磁盘等分为100个子区域，这100个子区域可以通过0-99的数字来表示。其中，0可以表示0-1％的存储空间，1可以表示1-2％的存储空间， 以此类推。然后，可以在所述指定数量的子区域中确定所述坏道数据中各个元素值对应的目标子区域。具体地，首先以4KB为单位，确定目标磁盘的总容量(目标磁盘的实际容量中包含的4KB的数量)。然后可以用元素值除以该目标磁盘的总容量，然后将得到的结果取整，从而可以确定该元素值具体对应哪一个子区域。这样，确定出的目标子区域均可以作为存在坏道的子区域。请参阅图3，图3中填充阴影的子区域便可以作为存在坏道的目标子区域。
在本实施例中，在确定出各个坏道所处的目标子区域之后，为了避免坏道的区域过于离散，可以将间隔满足指定条件的两个相邻的目标子区域进行合并，从而得到多个合并区域。具体地，在对目标子区域进行合并时，可以采用适配的区域来覆盖间隔满足指定条件的多个目标子区域。所述间隔满足指定条件可以指相邻两个目标子区域之间间隔的子区域的数量小于或者等于指定数量阈值。例如，所述指定数量阈值为2(目标磁盘总容量的2％)，那么只要相邻两个目标子区域之间的间隔不超过2个子区域，就可以将这两个相邻的目标子区域进行合并。请参阅图3，第一个和第二个目标子区域之间，相隔了1个子区域，因此可以将这两个目标子区域进行合并，在对这两个目标子区域进行合并时，需要将这两个目标子区域之间包含的子区域也一起合并，因此，初步合并后的该合并区域中，可以包括三个子区域。同理，由于第二个目标子区域与第三个目标子区域之间间隔了4个子区域，不满足合并条件，因此不会将第二个目标子区域与第三个目标子区域进行合并。而第三、第四以及第五个目标子区域均满足合并条件，因此可以将这三个目标子区域连同它们之间间隔的子区域一同合并，合并后的合并区域中可以包括四个子区域。
在本实施例中，在将目标子区域合并为合并区域之后，可以在各个所述合并区域的头部和/或尾部确定隔离区域，例如，该隔离区域可以是1个子区域(目标磁盘总容量的1％)，并将所述合并区域与所述隔离区域的组合作为合并后的坏道区域。例如在图3中，第一个合并区域由于在目标磁盘的头部，因此 仅在合并区域的尾部将一个子区域作为隔离区域，这样，最终可以将虚线框中的4个子区域作为坏道区域。同理，第二个合并区域由于处于目标磁盘的中间，因此头部和尾部均可以确定1个子区域作为隔离区域，这样，虚线框中的6个子区域可以作为坏道区域。
在本实施例中，在对坏道进行隔离，得到坏道区域之后，目标磁盘中剔除坏道区域以外的区域，便可以作为可用区域。
在一个实施例中，若在指定时长内无法完成坏道测试的过程，则可以发
送报警信息，从而通知管理人员直接更换磁盘。例如，超过48小时还未完成坏道测试过程，则表明磁盘中坏道过多或者磁盘出现严重的读写错误，从而可以放弃坏道隔离的过程，直接更换磁盘。
S5：根据检测结果，判断所述目标磁盘是否可用，若可用，基于所述可用区域重新构建所述目标磁盘的存储空间，并为重新构建的所述存储空间设置接入参数。
在本实施例中，在对坏道进行检测以及隔离之后，可以根据检测结果，判断该目标磁盘是否可以继续使用。具体地，可以通过对坏道数量、可用区域的空间容量以及可用区域的分区数量这三个方面进行综合考量。若检测到的坏道的数量大于指定坏道数量阈值，或者得到的可用区域的空间容量小于指定容量阈值，或者按照所述可用区域进行分区后的分区数量大于指定分区数量阈值，可以判定所述目标磁盘不可用。例如，若坏道数量超过200个，或者可用区域的空间容量低于目标磁盘总容量的90％，或者可用区域的分区数量超过4个，均判定目标磁盘不可用。相反，若检测到的坏道的数量小于或者等于所述指定坏道数量阈值，并且得到的可用区域的空间容量大于或者等于所述指定容量阈值，并且按照所述可用区域进行分区后的分区数量小于或者等于指定分区数量阈值，可以判定所述目标磁盘可用。例如，若坏道数量不超过200个，并且可用区域的空间容量不低于目标磁盘总容量的90％，并且可用区域的分区数 量不超过4个，可以判定目标磁盘可用。
在本实施例中，针对不可用的目标磁盘，可以发出告警信息，通知管理人员更换磁盘。而对于可用的目标磁盘，可以按照所述可用区域，将所述目标磁盘划分为多个分区。具体地，可以将连续的多个可用区域划分为一个分区。例如，在图3中，虚线框以外的空白子区域均为可用区域，那么可以将剩余的可用区域划分为两个分区，第一分区中包含2个子区域，第二个分区中仅包含1个子区域。在将可用区域划分为多个分区之后，可以通过LVM(Logical Volume Manager，逻辑卷管理)功能，将所述多个分区合并为一个卷，并将合并后的所述卷作为重新构建的存储空间。
在本实施例中，在检测所述目标磁盘中的坏道数据之前，可以记录所述目标磁盘的卷标和挂载点，这样，在得到重新构建的存储空间之后，可以格式化重新构建的所述存储空间，并将记录的所述目标磁盘的卷标和挂载点分别设置为格式化后的存储空间的卷标和挂载点，从而完成接入参数的设置过程。
在本实施例中，完成坏道隔离以及合并卷处理后的目标磁盘可以继续使用，因此，可以恢复所述目标磁盘中的业务或者恢复所述目标磁盘所处服务器中的业务。
