Description

一种数据存储方法、装置及存储介质
本申请要求于2020年02月26日提交中国专利局、申请号为202010118424.3发明名称为“一种数据存储方法、装置及存储介质”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及存储技术领域，特别涉及一种数据存储方法、装置及存储介质。
背景技术
当硬盘发生异常时，如果向硬盘写入数据，则可能会出现存储失败等问题而导致数据丢失。
为了减少硬盘异常情况的出现，通常会采取一些措施以保证数据存储的安全性，例如在硬盘托架下方添加减少振动的减震垫以减小硬盘振动情况的发生。然而这些措施是无法完全避免硬盘内部异常的，这就需要对硬盘是否发生异常进行检测。现有技术中，对硬盘是否发生异常情况的检测，通常是在存储设备里添加相关的传感器，比如在硬盘架的连接处添加振动传感器，或者在存储设备的背板上设置温度监控点等，根据传感器采集到的硬盘所处环境的相关信息判断硬盘是否发生异常，由于需要添加相关传感器，因此检测成本较高。
发明内容
有鉴于此，本申请的目的在于提供一种数据存储方法、装置及存储介质，能够在存储设备的硬盘出现异常时对硬盘实施隔离保护同时也保护数据不丢失，且实现成本较低。
为了达到上述目的，本申请提供了如下技术方案：
一种数据存储方法，应用于存储设备，该方法包括：
获取所述存储设备的硬盘内部异常信息；
根据所述硬盘内部异常信息判断所述存储设备的硬盘内部是否异常；
判定所述存储设备的硬盘内部异常，则将待存储数据存储到预先配置的存储空间，并在确定所述存储设备的硬盘内部异常恢复后，从预先配置的存 储空间读取待存储数据，将读取的待存储数据存储到所述存储设备的硬盘中；
判定所述存储设备的硬盘内部正常，则将待存储数据存储到所述存储设备的硬盘中。
一种数据存储装置，应用于存储设备，该装置包括：处理器、以及与所述处理器通过总线相连的非瞬时计算机可读存储介质；
所述非瞬时计算机可读存储介质，存储有可被所述处理器执行的一个或多个计算机程序；所述处理器执行所述一个或多个计算机程序时实现以下步骤：
获取所述存储设备的硬盘内部异常信息；
根据所述硬盘内部异常信息判断所述存储设备的硬盘内部是否异常；
判定所述存储设备的硬盘内部异常，则将待存储数据存储到预先设定的存储空间，并在确定所述存储设备的硬盘内部异常恢复后，从预先设定的存储空间读取待存储数据，将读取的待存储数据存储到所述存储设备的硬盘中；
判定所述存储设备的硬盘内部正常，则将待存储数据存储到所述存储设备的硬盘中。
一种非瞬时计算机可读存储介质，所述非瞬时计算机可读存储介质存储指令，所述指令在由处理器执行时使得所述处理器执行如上述数据存储方法中的步骤。
由上面的技术方案可知，本申请中，通过获取所述存储设备的硬盘内部异常信息，并据此判断所述存储设备的硬盘内部是否异常，在所述存储设备的硬盘内部异常时，将待存储数据存储到预先配置的存储空间，并在确定所述存储设备的硬盘内部异常恢复后，从预先配置的存储空间读取待存储数据，将读取的待存储数据存储到所述存储设备的硬盘中；在所述存储设备的硬盘内部正常时，将待存储数据存储到所述存储设备的硬盘中。可以看出，本申请中由于在硬盘异常时将待存储数据存储到预先配置的存储空间，而不是继续向硬盘写数据，可以起到隔离硬盘以保护其不会在异常情况下继续被使用而造成更大损害的目的，同时也可以达到保护数据不丢失的目的，而且判断存储设备的硬盘内部异常与否时不需要额外添加传感器，实现成本较低。
附图说明
为了更清楚地说明本申请实施例中的技术方案，下面将对实施例描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本申请的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动性 的前提下，还可以根据这些附图获得其他的附图。

从图2所示本申请实施例可以看出，本申请通过获取所述存储设备的硬盘内部异常信息并据此判断所述存储设备的硬盘内部异常与否，在判定存储设备的硬盘异常时，利用预先配置的存储空间存储待存储数据，而不是继续向硬盘写数据，可以起到隔离硬盘以保护其不会在异常情况下继续被使用而造成更大损害的目的，同时也可以达到在存储设备的硬盘出现异常时保护数据不丢失的目的。而且本申请是利用存储设备生产者提供的硬盘内部异常工具，或存储设备的操作系统自带的硬盘检测工具来获取存储设备的硬盘内部异常信息，此过程是利用已有工具实现，不需要额外添加和使用传感器，实现成本较低。
实施例三
参见图3，图3是本申请实施例三数据存储方法流程图，该方法应用于存储设备，如图3所示，该方法主要包括以下步骤：
步骤301、获取所述存储设备的硬盘内部异常信息。
具体的，在一种实施例中可以是利用存储设备生产者提供的硬盘内部异常工具获取存储设备的硬盘内部异常信息，或者，利用存储设备的操作系统自带的硬盘检测工具获取存储设备的硬盘内部异常信息。
在实际应用中，硬盘异常可包括多种异常类型，如振动异常、冲击异常、温度异常、机械结构异常(如连接线的连接异常)、气压异常等，其中任意一种异常类型的硬盘异常发生时，都有可能导致硬盘不可用，需要隔离。
本申请实施例中，硬盘内部异常信息可包括以下异常类型的异常信息的任意组合：振动异常信息、冲击异常信息、温度异常信息、机械结构异常信息、气压异常信息。在其他可能的实施例中，硬盘内部异常信息也可以包括除上述五种异常信息以外的其他异常信息。
步骤3021、根据所述硬盘内部异常信息包括的每种异常类型的异常信息，确定所述硬盘内部是否发生该种异常类型的硬盘异常。
本步骤3021具体可以包括：
S11、当硬盘内部异常信息包括振动异常信息时，根据振动异常信息判断存储设备的硬盘内部是否出现振动异常。
在本申请的一个实施例中，振动异常信息可以包括：振动强度和振动异常日志。存储设备生产者提供的硬盘内部异常工具可以根据磁头写碟面的内部重新尝试次数确定所述存储设备的硬盘的振动强度，如果内部重新尝试次数较多超过内部阈值就会标记存在振动，因为磁头写数据时如果存在振动，写碟面就会写失败，就会尝试多次写，通过此数据即可判断是否存在振动情况。另外，当存储设备生产者提供的硬盘内部异常工具检测到硬盘振动时，可以将检测时间和振动强度作为一条日志记录写入振动异常日志，如果在一个持续时间段(如3分钟)内的振动异常日志中的多数记录都表明硬盘振动时，则可确定硬盘在持续振动，发生了振动异常，其中，多数记录都表明硬盘振动可以是指表明硬盘震动的记录与振动异常日志中总记录数的比例超过预设比例阈值的记录，也可以是指表明硬盘震动的记录超过预设数目阈值。
因此，在所述硬盘内部异常信息包括振动异常信息的情况下，获取存储设备的振动异常信息的具体方法可以为：利用存储设备生产者提供的硬盘内部异常工具获取存储设备的硬盘当前时间的振动强度，当振动强度超过预设强度阈值时，获取存储设备的硬盘在当前时间之前第一预设时长内的振动异 常日志，其中，第一预设时长可以是根据实际需求和/或经验设置的一个时长，如3分钟、5分钟等。
上述步骤S11中，根据振动异常信息判断存储设备的硬盘内部是否出现振动异常，可以包括：统计存储设备的硬盘在当前时间之前第一预设时长内的振动异常日志中振动强度超过预设强度阈值的记录数与总记录条数的比例，如果比例超过预设比例阈值，则确定存储设备的硬盘内部出现振动异常，否则，确定存储设备的硬盘内部未出现振动异常。
在本申请的另一实施例中，振动异常信息可以包括参数：数据定位错误率(Seek_Error_Rate)和读写定位时间(Seek_Time_Performance)，这两个参数的取值过高时，表明硬盘碟面旋转偏心或磁头不能准确定位，而硬盘碟面旋转偏心和磁头不能准确定位可能是由振动异常导致的，即在这两个参数的取值过高时可以确定硬盘内部发生振动异常，因此这两个参数也可用于确定硬盘内部是否发生振动异常。这两个参数可利用存储设备的操作系统自带的硬盘检测工具(如smartctl)获得。
因此，在硬盘内部异常信息包括振动异常信息时，获取存储设备的振动异常信息的方法具体可以为：利用存储设备的操作系统自带的硬盘检测工具获取存储设备的硬盘的数据定位错误率和读写定位时间。
上述步骤S11中，根据振动异常信息判断存储设备的硬盘内部是否出现振动异常，具体可以包括：如果存储设备的硬盘的数据定位错误率超过预设定位错误率阈值，和/或存储设备的硬盘的读写定位时间超过预设定位时间阈值，则确定存储设备的硬盘内部出现振动异常，否则，确定存储设备的硬盘内部未出现振动异常。
S12、当硬盘内部异常信息包括冲击异常信息时，根据冲击异常信息判断存储设备的硬盘内部是否出现冲击异常。
在本申请的一个实施例中，冲击异常信息可以包括：冲击异常日志。在实际应用中，当有明显的撞击物撞击存储设备的硬盘时，存储设备可以在硬盘内部记录冲击异常日志，因此可以从存储设备的硬盘中读出当前时间之前一段时间(例如24小时)内的冲击异常日志，并分析冲击异常日志中是否存在冲击异常记录，存在冲击异常记录则可确定存储设备的硬件内部发生冲击异常。存储设备的硬盘的冲击异常日志可利用存储设备生产者提供的硬盘内部异常工具获得。
因此，在硬盘内部异常信息包括冲击异常信息的情况下，获取存储设备的冲击异常信息的方法具体可以为：利用存储设备生产者提供的硬盘内部异常工具获取存储设备的硬盘在当前时间之前第二预设时长内的冲击异常日志。
上述步骤S12中，根据冲击异常信息判断存储设备的硬盘内部是否出现冲击异常，具体包括：判断存储设备的硬盘在当前时间之前第二预设时长内的冲击异常日志中是否有冲击异常记录，如果是，则确定存储设备的硬盘内部出现冲击异常，否则，确定存储设备的硬盘内部未出现冲击异常。
在本申请的另一实施例中，冲击异常信息可以包括参数：磁头飞行高度(High_Fly_Writes)和冲击错误率(G-Sense_Error_Rate)。磁头飞行高度过高表明硬盘磁头读取数据出现问题，而硬盘磁头读取数据出现问题可能是由于硬盘出现冲击异常导致的；冲击错误率过高表示存在冲击事件，如果冲击错误率一直增加到超过一定阈值，则说明硬盘出现冲击异常。使用这两个参数均可判定存储设备的硬盘内部是否出现冲击异常，可以利用存储设备的操作系统自带的硬盘检测工具(如smartctl)获得这两个参数。
因此，在硬盘内部异常信息包括冲击异常信息的情况下，获取存储设备的冲击异常信息的具体方法还可以为：利用存储设备的操作系统自带的硬盘检测工具获取存储设备的硬盘的磁头飞行高度和冲击错误率。
上述步骤S12中，根据冲击异常信息判断存储设备的硬盘内部是否出现冲击异常，具体可以包括：如果存储设备的硬盘的磁头飞行高度超过预设高度阈值，和/或存储设备的硬盘的冲击错误率超过预设冲击错误率阈值，则确定存储设备的硬盘内部出现冲击异常，否则，确定存储设备的硬盘内部未出现冲击异常。
S13、当硬盘内部异常信息包括温度异常信息时，根据温度异常信息判断存储设备的硬盘内部是否出现温度异常。
本申请实施例中，温度异常信息包括：硬盘温度。可利用存储设备的操作系统自带的硬盘检测工具(如smartctl)获取存储设备的硬盘的温度。
因此，在硬盘内部异常信息包括温度异常信息的情况下，获取存储设备的温度异常信息的方法具体可以为：利用存储设备的操作系统自带的硬盘检测工具获取存储设备的硬盘的温度。
上述步骤S13中，根据温度异常信息判断存储设备的硬盘内部是否出现温度异常，具体可以包括：如果存储设备的硬盘的温度超过预设温度阈值，则确定存储设备的硬盘内部出现温度异常，否则，确定存储设备的硬盘内部未出现温度异常。
S14、当硬盘内部异常信息包括机械结构异常信息时，根据机械结构异常信息判断存储设备的硬盘内部是否出现机械结构异常。
在本申请的一个实施例中，机械结构异常信息可以包括：结构异常标志；结构异常标志具有两种取值，分别是：指示结构异常的值和指示结构正常的 值。机械结构异常标志可利用存储设备生产者提供的硬盘内部异常工具获得。存储设备生产者提供的硬盘内部异常工具可以判断出存储设备的硬件内部是否存在连接线问题、信号传输问题等，然后根据判断结果返回机械结构异常标志。
因此，在硬盘内部异常信息包括机械结构异常信息的情况下，获取存储设备的机械结构异常信息的方法具体可以为：利用存储设备生产者提供的硬盘内部异常工具获取存储设备的硬盘的结构异常标志值。
上述步骤S14中，根据机械结构异常信息判断存储设备的硬盘内部是否出现机械结构异常，具体可以包括：判断存储设备的硬盘的结构异常标志值是否是指示结构异常的值，如果是，则确定存储设备的硬盘内部出现机械结构异常，否则，确定存储设备的硬盘内部未出现机械结构异常。
在本申请的另一实施例中，机械结构异常信息可以包括参数：接口CRC写入错误计数(CRC_Error_Count)。此参数可用于判断连接线问题，可利用存储设备的操作系统自带的硬盘检测工具获得。
因此，在硬盘内部异常信息包括机械结构异常信息的情况下，获取存储设备的机械结构异常信息的方法具体可以为：利用存储设备的操作系统自带的硬盘检测工具获取存储设备的硬盘的接口CRC写入错误计数。
上述步骤S14中，根据机械结构异常信息判断存储设备的硬盘内部是否出现机械结构异常，具体可以包括：如果存储设备的硬盘的接口CRC写入错误计数超过预设计数阈值，则确定存储设备的硬盘内部出现机械结构异常，否则，确定存储设备的硬盘内部未出现机械结构异常。
S15、当硬盘内部异常信息包括气压异常信息时，根据气压异常信息判断存储设备的硬盘内部是否出现气压异常。
本申请实施例中，气压异常信息包括：气压异常标志；气压异常标志具有两种取值，分别是：指示气压异常的值(例如0)和指示气压正常的值(例如1)。气压异常标志可利用存储设备的操作系统自带的硬盘检测工具获得。
因此，在硬盘内部异常信息包括气压异常信息的情况下，获取存储设备的气压异常信息的方法具体可以为：利用存储设备的操作系统自带的硬盘检测工具获取存储设备的硬盘的气压异常标志值。
上述步骤S15中，根据气压异常信息判断存储设备的硬盘内部是否出现气压异常，具体包括：如果存储设备的硬盘的气压异常标志值是指示气压异常的值，则确定存储设备的硬盘内部出现气压异常，否则，确定存储设备的硬盘内部未出现气压异常。
以上步骤S11至S15的执行不分先后顺序，并且可以是依次执行的，也 可以是并行执行的，还是可以是交替执行的。
步骤3022、当存储设备的硬盘内部发生任意一种异常类型的硬盘异常时，确定存储设备的硬盘内部异常。
本申请实施例中，由于任意一种异常类型的硬盘异常都可能导致硬盘不可用，因此，不论硬盘内部异常信息包括几种异常类型的异常信息，只要根据其中任意一种异常类型的异常信息确定存储设备的硬盘内部发生该种异常类型的硬盘异常(例如振动异常)，则就认为存储设备的硬盘内部异常。
当确定存储设备的硬盘内部异常时，需要隔离存储设备的硬盘，不再将待存储数据存储到硬盘中，而是利用预先配置的存储空间暂时存储待存储数据，即执行步骤303。
步骤3023、当存储设备的硬盘内部未发生任何异常类型的硬盘异常时，确定存储设备的硬盘内部正常。
本申请实施例中，当存储设备的硬盘内部未发生振动异常、冲击异常、温度异常、机械结构异常、及气压异常中的任何一种异常类型的硬盘异常时，认为存储设备的硬盘内部正常。
当确定存储设备的硬盘内部正常时，不需要隔离存储设备的硬盘，因此可以直接将待存储数据存储到硬盘中，即执行步骤304。
步骤303、将待存储数据存储到预先配置的存储空间，并在确定存储设备的硬盘内部异常恢复后，从预先配置的存储空间读取待存储数据，将读取的待存储数据存储到存储设备的硬盘中。
在本申请实施例中，在将存储数据存储到预先配置的存储空间时，还会定期检测存储设备的硬盘内部是否从异常中恢复(即恢复正常)，当确定存储设备的硬盘内部从异常中恢复后，可以将此前存储到预先配置的存储空间中的待存储数据读取出来并存储到存储设备的硬盘中，此过程中可利用断点续传/断网续传等方法以保证数据存储的连续性和不丢失。
本申请实施例中，预先配置的存储空间可以是存储设备的缓存，也可以是预先添加到存储设备中系统卡(即存储设备的操作系统所在磁盘)或固态硬盘(SSD)。另外，当存储设备的硬盘是RAID磁盘阵列中的一个磁盘时，预先配置的存储空间可以是RAID磁盘阵列的一个热备盘，这种情况下，当存储设备的硬盘内部异常时，在用该热备盘替代存储设备的硬盘存储数据之前，可以将存储设备的硬盘从磁盘阵列中剔除出去，当存储设备的硬盘异常恢复后，再重新将存储设备的硬盘添加到RAID磁盘阵列中。
步骤304、将待存储数据存储到存储设备的硬盘中。
从图3所示本申请实施例可以看出，本申请中在获取存储设备的硬盘内 部异常信息后，根据硬盘内部异常信息中的每种异常类型的异常信息判断存储设备的硬盘是否发生该种异常类型的硬盘异常，从而在确定存储设备的硬盘发生任意一种异常类型的硬盘异常，均判定存储设备的硬盘内部异常，并在判定存储设备的硬盘异常时，利用预先配置的存储空间存储待存储数据，而不是继续向硬盘写数据，可以起到隔离硬盘以保护其不会在异常情况下继续被使用而造成更大损害的目的，同时也可以达到在存储设备的硬盘出现异常时保护数据不丢失的目的，且实现成本较低。另外，本申请中，通过分别根据每种异常类型的异常信息判断存储设备的硬盘是否发生该种异常类型的硬盘异常，可以在确定存储设备的硬盘内部异常时，同时确定存储设备的硬盘内部异常的异常类型，从而可以有助于工作人员后续对硬盘的修复。
以上用三个实施例对本申请提供的数据存储方法进行了详细说明，在实际应用中，数据存储过程具体可以如图4所示，一方面，硬盘异常检测模块41定期利用存储设备生产者提供的硬盘内部异常工具或存储设备的操作系统自带的硬盘检测工具获取硬盘内部异常信息，并据此判定硬盘内部是否出现异常，将判定结果(也即异常检测结果)通知给业务数据存储模块42，例如可以设置一个能够被硬盘异常检测模块41和业务数据存储模块42访问的硬盘异常标志，硬盘异常检测模块41可以通过对此硬盘异常标志设置指示硬盘异常的值或指示硬盘正常的值来通知异常检测结果；另一方面，业务数据存储模块42在存储数据时，根据硬盘异常标志来确定硬盘是否出现异常，并根据硬盘内部是否出现异常来确定如何进行存储，具体地，当硬盘内部正常时，直接将待存储数据存储到硬盘中，当硬盘内部出现异常时，对硬盘实施隔离保护，将待存储数据存储到预先配置的存储空间(如缓存、系统卡、SSD等)中，并在硬盘内部异常恢复后，通过断点续传等技术手段，将存储到预先配置的存储空间的待存储数据重新存回到硬盘中。
以上对本申请实施例数据存储方法进行了详细说明，本申请还提供了一种数据存储装置，以下结合图5进行详细说明。
