Mounting NFS in FreeBSD 12.0 in AWS/EFS

[Rafal Lukawiecki]

Hello Everyone, Hi Colin,

In FreeBSD 11.1 I mount AWS EFS using:

	mount -t nfs -o rw,nfsv4,oneopenown,rsize=1048576,wsize=1048576,hard,timeo=600,retrans=2

I understand that 12.0 had a few changes to NFS, including the long-awaited support for 64-bit inodes. Is there a newer/better/more recommended way to mount now? AWS suggest, for Linux, using nfsvers=4.1, and their mount looks like this (I realise the slight difference in syntax):

	mount -t nfs4 -o nfsvers=4.1,rsize=1048576,wsize=1048576,hard,timeo=600,retrans=2,noresvport 

Many thanks for any suggestions and regards from Ireland,
Rafal
