问题描述

  • 用户无法在 ONTAP 9.12.1 之前版本中创建的 Vservers (SVM) 上装载 NFS 共享
    注意:此缺陷的暴露仅限于在 9.12.1 之前版本中创建的 SVM。
  • 某些客户端无法访问文件或目录
  • 将 ONTAP 升级到 9.12.1 后,NFS 选项 "v4.2-xattrs" 在最初几个小时内在启用、禁用和重新启用之间来回切换。

示例 SKTRACE.GZ:
[2024-01-07T09:23:41Z 1357141480396 [13:0] NfsInfo_1: insertNfsOptions: EVENT: OPT_nfsV42XattrsEnable_MODIFIED, VS_ID: 4, old: 0, new: 1]
[2024-01-07T09:24:01Z 1405731180402 [13:0] NfsInfo_1: insertNfsOptions: EVENT: OPT_nfsV42XattrsEnable_MODIFIED, VS_ID: 3, old: 1, new: 0]
[2024-01-07T09:24:01Z 1405763975674 [15:0] NfsInfo_1: insertNfsOptions: EVENT: OPT_nfsV42XattrsEnable_MODIFIED, VS_ID: 4, old: 1, new: 0]
  • 在 ONTAP 升级之前,v4.2-xattr 选项从未显式分配值
  • NFSv4.2 客户端未被告知服务器的扩展属性选项已更改,从而在客户端和服务器不匹配时导致对特定 xattr 调用的 NFS 响应错误。
