摘要： 本发明涉及一种解决存储磁盘阵列Write Hole的处理方法，于设计RAID时，采用文件系统的Journal日志设计方式进行写请求的原子处理；采用非易失性的快速设备做为写缓存，达到原子写操作的目的。本发明在实现写请求的原子处理过程中，journal盘由SSD固态硬盘与HDD机械硬盘组合而成，并且先通过对io块的大小进行解析，再根据io块的大小不同而分别写入不同journal盘，若io块为小块，则将小块io并写入journal‑SSD；若io块为大块，则将大块io并写入journal‑HDD；若io块为小块且为连续状态，则写入journal‑HDD，从而避免Write Hole问题的出现。

摘要： 本发明提供一种在存储阵列中处理WriteHole的方法，其处理过程为：互为冗余控制器对的存储系统中，在RAID5降级时将本端控制器所写数据备份到对端控制器。待本端控制器成功写入后，再通知对端控制器释放所备份数据。如果本端控制器在刷写磁盘的时候，控制器故障。对端控制器接管本端控制器存储资源时，重启RAID5将备份数据写到对应的磁盘上。该一种在存储阵列中处理WriteHole的方法和现有技术相比，提高RAID5磁盘阵列的数据一致性、稳定性，实用性强，易于推广。

摘要： 本发明公开了一种ceph+tgt架构中SCSI指令WRITE_SAME函数的实现方法及装置，该方法包括：向WRITE_SAME函数分配预定缓存；将待写入数据重复复制至所述预定缓存，以通过所述待写入数据填满所述预定缓存；通过rbd_write()接口，将填满的所述预定内存写入后端存储；可见，相对于现有方案中需要通过频繁调用rbd_write()接口实现数据写入的方式，在本方案中，预先将待写入数据写入预定缓存，便可通过调用一次rbd_write()接口实现将待写入数据写入后端存储，从而极大优化了write_same的实现方式，解决了Ceph+tgt架构对vmware系统兼容性问题。
