NFS version 4?
Is there a way to enable a share to use NFS v4? The network here uses NFS v4 (and generally the Unix machines use Active Directory for user lookups, for ease of management) on most systems utilizing N...
My 2100, RAIDiator 4.1.6, does support v4, as well as 2 and 3.
sudo rpcinfo -p backupserver | grep nfs
100003 2 udp 2049 nfs
100003 3 udp 2049 nfs
100003 4 udp 2049 nfs
100003 2 tcp 2049 nfs
100003 3 tcp 2049 nfs
100003 4 tcp 2049 nfs
Replace "backupserver" with your NAS IP address.
The problem is the config file needs an additional parameter which defines the NFS v4 pseudo-filesystem root (only define one at the top level). You then only need to mount the root "backupserver:/" in v4, which in my config actually mounts the NAS /backup directory. So I only have one NFS share, so added "fsid=0" to the /etc/exports
"/backup" *(fsid=0,insecure,insecure_locks,rw,async)
To mount my local directory /archive I use
sudo mount -t nfs4 -o rw,hard,intr,bg backupserver:/ /archive
Note backupserver:/ is used as you mount the root only, don't use the actual share name like /backup.
