适用场景

  • ONTAP 9
  • NFSv4.x
  • 使用中继的NFSv4.x客户端
  • Coheesity备份应用程序

问题描述

  • 使用NFSv4.1 中继功能时、客户端会遇到I/O错误、并且可能无法正确写入文件
  • 在使用NFSv4.1从Cohesity备份应用程序执行恢复/还原时、注意到数据当前情况、因为md5sum与还原后文件的数据当前情况不同
  • 备份前文件的MD5SUM:

root@server /mnt/nfsv4.1]# md5sum filename
2672eb7b5f4dee9159f3519e4434bc43 filename

 

  • 备份并还原 到不同ONTAP路径后、同一文件的MD5SUM:

root@server /mnt/nfsv4.1/restore_path] md5sum filename
2672eb7b5f4dee9159f3519e4436sg74  filename

  • 问题描述正在影响大小较大的文件(<=1GB)
