Re: NFS doesn't work – RPC errors

Enable rpcbind on the server and on the client. Make sure to not run systemd 219 on both sides.

Re: NFS doesn't work – RPC errors

I run 218 and rpcbind is enabled, but starting doesn't affect the outcome of the NFS mounts.

from the link:

Enabling rpc-statd allows nfs3, and installing the testing from package makes sure the ordering is okay and statd actually runs in time.

– doesn't work sadly. Same errors.

EDIT: Found an error on the server:

rpc.nfsd[354]: rpc.nfsd: writing fd to kernel failed: errno 111 (Connection refused)
rpc.nfsd[354]: rpc.nfsd: unable to set any sockets for nfsd

EDIT2: and this

kernel: svc: failed to register nfsdv3 RPC service (errno 97).
kernel: svc: failed to register nfsaclv3 RPC service (errno 97).
kernel: svc: failed to register lockdv1 RPC service (errno 97).

Re: NFS doesn't work – RPC errors

I just had this problem, but on my Gentoo box (the only machine I mount and NFS share on...)

Solution from another Arch user is to make sure rpc-bind is enabled:

systemctl enable rpcbind && systemctl start rpcbind

This fixed it for me and the systemd automounter works as usual.

Re: NFS doesn't work – RPC errors

Check what error messages you get when mounting manually.

# mount -t nfs 10.0.0.4:/films /mnt/server/films

Do you have the same uid and gid on server and client?
Showing the exports file might get you help, too.
