fedfs-delete-replication: send a FEDFS_DELETE_REPLICATION ADMIN protocol request

NAME

fedfs-delete-replication - send a FEDFS_DELETE_REPLICATION ADMIN protocol request

SYNOPSIS

fedfs-delete-replication [-?d] [-n nettype] [-h hostname] [-s security] path

INTRODUCTION

RFC 5716 introduces the Federated File System (FedFS, for short). FedFS is an extensible standardized mechanism by which system administrators construct a coherent namespace across multiple file servers using file system referrals. For further details, see fedfs(7).

FedFS-enabled file servers allow remote administrative access via an authenticated RPC protocol known as the FedFS ADMIN protocol. Using this protocol, FedFS administrators manage FedFS junctions and NSDB connection parameter information on remote FedFS-enabled file servers.

DESCRIPTION

The fedfs-delete-replication(8) command is part of a collection of low-level single-use programs that is intended for testing the FedFS ADMIN protocol or for use in scripts. It sends a single FEDFS_DELETE_REPLICATION request to a remote FedFS ADMIN protocol service.

The FEDFS_DELETE_REPLICATION request deletes a replication marker in a local file system on a remote file server. The fedfs-delete-replication(8) command taks a single positional parameter which is the pathname on the remote server of the replication marker to be deleted. This pathname is relative to the root of the local file system on the remote server.

OPTIONS

-d, --debug

Enables debugging messages during operation.

-?, --help

Displays fedfs-delete-replication(8) version information and a usage message on stderr.

-h, --hostname=hostname

Specifies the hostname of a remote FedFS ADMIN service. If this option is not specified, the default value is localhost.

-n, --nettype=nettype

Specifies the transport to use when contacting the remote FedFS ADMIN service. Typically the nettype is one of tcp or udp. If this option is not specified, the default value is netpath. See rpc(3t) for details.

-s, --security=flavor

Specifies the security flavor to use when contacting the remote FedFS ADMIN service. Valid flavors are sys, unix, krb5, krb5i, and krb5p. If this option is not specified, the unix flavor is used. See the SECURITY section of this man page for details.

EXAMPLES

Suppose you are the FedFS administrator of the example.net FedFS domain. To delete an existing FedFS replication on the remote server fs.example.net, use:

$ fedfs-delete-replication -h fs.example.net /export/replication1

SECURITY

By default, or if the sys and unix flavors are specified with the --security=flavor option, the fedfs-create-junction(8) command uses AUTH_SYS security for the Remote Procedure Call. AUTH_SYS has known weaknesses and should be avoided on untrusted networks.

The RPC client uses the Kerberos v5 GSS mechanism if a Kerberos security flavor is specified. When specifying a Kerberos security flavor, the user must first obtain a valid Kerberos ticket using kinit(1) before running fedfs-create-junction(8).

The AUTH_NONE security flavor is no longer supported by this implementation.
