OSX using NFSv4 caused the panic . I have disabled NFSv4 on
napinst which was the only one using it. But it affected
napinst and napcluster were not available during the downtime but naproj was ok. naphome I believe was ok too.
Mounts that are stuck will mean a client system reboot, if umount is not possible.
There will be a patch OS version coming out soon, and I can upgrade the netapp when it does, and renable NFSv4.
Until then all users on napinst clients will have to change NFS vers=4 to vers=3 if they are explicitly configured.
