vastnfs-ctl

This helper script is installed with the package, and can assist in various situations.

The usage of this script is optional in most cases.

Status

Observe the status of the loaded NFS services and kernel modules

vastnfs-ctl status

Example output:

version: v4.0-pre4-11-ge520dd8eb9cb
kernel modules: sunrpc rpcrdma compat_nfs_ssc lockd nfs_acl auth_rpcgss nfsd rpcsec_gss_krb5 nfs nfsv3 nfsv4
services: rpcbind.socket rpcbind
rpc_pipefs: /var/lib/nfs/rpc_pipefs

Reload

The following command will try to reload the NFS stack. It will first try to unmount all NFS file systems, and then reload all the necessary kernel modules.

vastnfs-ctl reload

Example output:

vastnfs-ctl: stopping service rpcbind.socket
vastnfs-ctl: umounting fs /var/lib/nfs/rpc_pipefs
vastnfs-ctl: unloading kmod nfsv4
vastnfs-ctl: unloading kmod nfsv3
