問題

  • Users are not able to mount NFS shares on Vservers (SVM) created in ONTAP pre-9.12.1
Note: Exposure to this defect is limited to SVMs that were created on a pre-9.12.1 release ONLY.
  • After upgrading ONTAP to 9.12.1, the NFS option "v4.2-xattrs" flips back and forth between enabled, disabled and re-enabled during first few hours.

Example 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]

  • The v4.2-xattr option was never explicitly assigned a value before the ONTAP upgrade
  • NFSv4.2 clients are not informed that the server's extended attributes option has changed, causing NFS response errors to specific xattr calls while the client and server mismatch.
