ONTAP-120160:NFS v4.2-xattrsフィールドがアップグレード後に反転
問題
- Users are not able to mount NFS shares on Vservers (SVM) created in ONTAP pre-9.12.1
- 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.

- 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.
