Description
技术领域technical field
本发明涉及信息存储技术领域，更具体的，涉及一种RAID系统故障的恢复方法及装置。The present invention relates to the technical field of information storage, and more specifically, to a recovery method and device for a RAID system failure.
背景技术Background technique
RAID是一个复杂的系统，linux平台中的软RAID是以块设备的形式提供给用户使用，并利用linux的通用块层作为RAID的cache缓冲管理，而且软RAID没有自己的IO调度模块，借助磁盘驱动完成IO的调度和处理。当创建RAID系统之后，在每个RAID系统成员盘中都会保存一份RAID的元数据信息，RAID系统通过元数据信息管理各成员盘。RAID is a complex system. Soft RAID on the Linux platform is provided to users in the form of block devices, and uses the general block layer of Linux as the cache buffer management of RAID. Moreover, soft RAID does not have its own IO scheduling module. The driver completes the scheduling and processing of IO. After the RAID system is created, a piece of RAID metadata information is saved in each member disk of the RAID system, and the RAID system manages each member disk through the metadata information.
当存储系统出现硬件链路故障导致JBOD(Just a Bunch Of Disks，磁盘簇)或者背板与主柜之间的SAS链路断开时，就会导致RAID系统成员盘之间的元数据信息不一致。此时即使将硬件链路恢复，RAID系统也无法恢复，要想恢复RAID系统，需要将掉线的磁盘中的数据进行转移，非常耗费时间。When the hardware link failure of the storage system causes the JBOD (Just a Bunch Of Disks, disk cluster) or the SAS link between the backplane and the main cabinet to be disconnected, the metadata information between the member disks of the RAID system will be inconsistent. . At this time, even if the hardware link is restored, the RAID system cannot be restored. To restore the RAID system, the data in the offline disk needs to be transferred, which is very time-consuming.

有鉴于此，本发明提供了一种RAID系统故障的恢复方法及装置，解决当出现硬件链路故障时导致RAID系统无法恢复的问题，缩短了RAID系统故障的恢复时间。In view of this, the present invention provides a recovery method and device for a RAID system failure, which solves the problem that the RAID system cannot be recovered when a hardware link failure occurs, and shortens the recovery time of the RAID system failure.

当硬件链路故障导致RAID系统部分RAID成员盘掉线后，需要工作人员人为将掉线的RAID成员盘拔下并重新插入槽位。通过监听磁盘的热插拔动作，检测是否有待添加磁盘，所述待添加磁盘即为掉线的RAID成员盘。When a hardware link failure causes some RAID member disks in the RAID system to go offline, the staff needs to manually unplug the offline RAID member disks and reinsert them into the slots. By monitoring the hot-swapping action of the disk, it is detected whether there is a disk to be added, and the disk to be added is a RAID member disk that is offline.
当检测到待添加磁盘时，首先需要判断所述待添加磁盘是否为RAID系统的成员盘，具体判断流程如下：When the disk to be added is detected, it is first necessary to judge whether the disk to be added is a member disk of the RAID system. The specific judgment process is as follows:
提取所述待添加磁盘的RAID信息；Extracting the RAID information of the disk to be added;

提示RAID故障恢复失败的方式可以为语音提示、文本提示、闪灯提示等任意一种可以起到提示作用的方式。The way of prompting that the RAID failure recovery fails can be any one of voice prompts, text prompts, and flashing light prompts that can play a prompt role.
S102：判断所述待添加磁盘的元数据与所述RAID系统已有成员盘的元数据是否一致，若是，执行S103，若否，执行S104；S102: Determine whether the metadata of the disk to be added is consistent with the metadata of the existing member disks of the RAID system, if yes, execute S103, if not, execute S104;
具体的，S102的执行过程如下：Specifically, the execution process of S102 is as follows:
计算所述待添加磁盘的元数据值与所述RAID系统已有成员盘的元数据值的差值；Calculate the difference between the metadata value of the disk to be added and the metadata value of the existing member disks of the RAID system;
判断所述差值是否大于预设值；judging whether the difference is greater than a preset value;
若是，所述待添加磁盘的元数据与所述RAID系统已有成员盘的元数据不一致；If so, the metadata of the disk to be added is inconsistent with the metadata of the existing member disks of the RAID system;
若否，所述待添加磁盘的元数据与所述RAID系统已有成员盘的元数据一致。If not, the metadata of the disk to be added is consistent with the metadata of an existing member disk of the RAID system.
优选的，所述预设值为2。Preferably, the preset value is 2.
S103：将所述待添加磁盘添加到所述RAID系统中；S103: Add the disk to be added to the RAID system;
S104：将所述待添加磁盘的元数据更新为所述RAID系统已有成员盘的元数据，并将所述待添加磁盘添加到所述RAID系统中。S104: Update the metadata of the disk to be added to the metadata of an existing member disk of the RAID system, and add the disk to be added to the RAID system.
具体的，当所述待添加磁盘的元数据与所述RAID系统已有成员盘的元数据不一致时，删除所述待添加磁盘的元数据，并将所述RAID系统已有成员盘的元数据拷贝到所述待添加磁盘中，使所述待添加磁盘的元数据更新为所述RAID系统已有成员盘的元数据。Specifically, when the metadata of the disk to be added is inconsistent with the metadata of the existing member disks of the RAID system, delete the metadata of the disk to be added, and replace the metadata of the existing member disks of the RAID system copy to the disk to be added, so that the metadata of the disk to be added is updated to the metadata of an existing member disk of the RAID system.
本实施例提供的RAID系统故障的恢复方法，当检测到待添加磁盘时，先判断所述待添加磁盘是否为RAID系统的成员盘，当所述待添加磁盘为RAID系统的成员盘时，判断所述待添加磁盘的元数据与所述RAID系统已有成员盘的元数据是否一致；若是，将所述待添加磁盘添加到所述RAID系统中；若否，将所述待添加磁盘的元数据更新为所述RAID系统已有成员盘的元数据，并将所述待添加磁盘添加到所述RAID系统中。有效的解决了由于硬件链路故障导致RAID系统故障的问题，不需要将掉线磁盘中的数据进行转移，只需更新掉线磁盘的元数据即可，缩短了RAID系统故障的恢复时间。The recovery method of the RAID system failure that this embodiment provides, when detecting that the disk to be added, first judge whether the disk to be added is a member disk of the RAID system, and when the disk to be added is a member disk of the RAID system, judge Whether the metadata of the disk to be added is consistent with the metadata of the existing member disks of the RAID system; if so, add the disk to be added to the RAID system; if not, add the metadata of the disk to be added The data is updated to the metadata of existing member disks of the RAID system, and the disk to be added is added to the RAID system. It effectively solves the problem of RAID system failure due to hardware link failure.
