	Delegations(enum, values [None, read, write, readwrite, r, w, rw],
		    default None)

	Attr_Expiration_Time(int32, range -1 to INT32_MAX, default 60)


EXPORT {}
---------

	* Take all the "export permissions" options from EXPORT_DEFAULTS.

	* The first 5 options are considered static from the perspective of
	  dynamic update.

	Path(path, no default, must be supplied)

	Pseudo(path, no default)

	Tag(string, no default)

	Export_id(uint16, range 0 to UINT16_MAX, default 1)

	Filesystem_id(fsid, format is uint64.uint64, default 666.666)

		* Updating Filesystem_id would have an adverse impact on
		  existing client mounts and it's not currently a type that
		  can be atomically updated.

	* The following options may be dynamically updated

	MaxRead(uint64, range 512 to 64*1024*1024, default 64*1024*1024)

	MaxWrite(uint64, range 512 to 64*1024*1024, default 64*1024*1024)

	* Note that some older nfs client (e.g. libnfs 1.x) would not handle
	  well for large Prefer Read/Write size. If so, please try to decrease
	  the Prefer Read/Write size  (usually less than 1M is suitable for
	  older nfs client).

	PrefRead(uint64, range 512 to 64*1024*1024, default 64*1024*1024)

	PrefWrite(uint64, range 512 to 64*1024*1024, default 64*1024*1024)

	MaxOffsetWrite(uint64, range 512 to UINT64_MAX, default INT64_MAX)

	MaxOffsetRead(uint64, range 512 to UINT64_MAX, default INT64_MAX)

	DisableReaddirPlus(bool, default false)

	Trust_Readdir_Negative_Cache(bool, default false)

	* The following options may have limits on dynamic effect

	UseCookieVerifier(bool, default true)

		* Updating UseCookieVerifier while a readdir is in
		  progress may result in unexpected behavior.

	Disable_ACL(bool, default false)

		* Disable_ACL is processed at create_export time currently
		  which makes it effectively a static option.

	sec_label_xattr(char, default "security.selinux xattr of the file")

		* Enable NFSv4.2 security label attribute. Ganesha supports
		  "Limited Server Mode" as detailed in RFC 7204. Note that
		  not all FSALs support security labels.

	Attr_Expiration_Time(int32, range -1 to INT32_MAX, default 60)

		* Attr_Expiration_Time is evaluated when an MDCACHE entry
		  is created, so the dynamic effect of this option may
		  be constrained to new entries.


EXPORT { CLIENT  {} }
---------------------

	* Take all the "export permissions" options from EXPORT_DEFAULTS.

	* The client lists are dynamically updateable.

	Clients(client list, empty)

	* Client list entries can take on one of the following forms:

	*		Match any client
	@name		Netgroup name
	x.x.x.x/y	IPv4 network address
	wildcarded	If the string contains at least one ? or *
			character (and is not simply "*"), the string is
			used to pattern match host names. Note that [] may
			also be used, but the pattern MUST have at least one
			? or *
	hostname	Match a single client (match is by IP address, all
			addresses returned by getaddrinfo will match, the
			getaddrinfo call is made at config parsing time)
	IP address	Match a single client

EXPORT { FSAL {} }
------------------

	Name(string, default "VFS")

	FSAL_CEPH:
	----------
	User_Id(string, no default)

	* User_Id: cephx userid used to open the MDS session. This string is
	  what gets appended to "client.". If not set, the ceph client libs
	  will sort this out based on ceph configuration.

	Secret_Access_Key(string, no default)

	* Secret_Access_Key: key to use for the session (if any). If not set,
	  then it uses the normal search path for cephx keyring files to find
	  a key.

------

	Default_log_level(token, values [NULL, FATAL, MAJ, CRIT, WARN, EVENT,
					 INFO, DEBUG, MID_DEBUG, M_DBG,
					 FULL_DEBUG, F_DBG], default none)

		If this option is NOT set, the fall back log level will be that
		specified in the -N option on the command line if that is set,
		otherwise the fallback level is EVENT.

		If a SIGHUP is issued, any components not specified in
		LOG { COMPONENTS {} } will be reset to this value.

	RPC_Debug_Flags(uint32, range 0 to UINT32_MAX, default 7)

		Debug flags for TIRPC (default 7 matches log level default EVENT).

		These flags are only used if the TIRPC component is set to DEBUG

	Display_UTC_Timestamp(bool, default false)

		If this is set to true, date and time in ganesha log file will
		use UTC timezone.

LOG { COMPONENTS {} }
---------------------

	These entries are of the form:

	COMPONENT = LEVEL;

	The components are: ALL, LOG, MEMLEAKS, FSAL, NFSPROTO,
			    NFS_V4, EXPORT, FILEHANDLE, DISPATCH, CACHE_INODE,
			    CACHE_INODE_LRU, HASHTABLE, HASHTABLE_CACHE, DUPREQ,
			    INIT, MAIN, IDMAPPER, NFS_READDIR, NFS_V4_LOCK,
			    CONFIG, CLIENTID, SESSIONS, PNFS, RW_LOCK, NLM, RPC,
			    TIRPC, NFS_CB, THREAD, NFS_V4_ACL, STATE, 9P,
			    9P_DISPATCH, FSAL_UP, DBUS, NFS_MSK

	Some synonyms are:

	FH = FILEHANDLE
	HT = HASHTABLE
	INODE_LRU = CACHE_INODE_LRU
	INODE = CACHE_INODE
	DISP = DISPATCH
	LEAKS = MEMLEAKS
	NFS3 = NFSPROTO
	NFS4 = NFS_V4
	HT_CACHE = HASHTABLE_CACHE
	NFS_STARTUP = INIT
	NFS4_LOCK = NFS_V4_LOCK
	NFS4_ACL = NFS_V4_ACL
	9P_DISP = 9P_DISPATCH

	The log levels are: NULL, FATAL, MAJ, CRIT, WARN, EVENT,
			    INFO, DEBUG, MID_DEBUG, M_DBG,
			    FULL_DEBUG, F_DBG], default none

	ALL is a special component that when set, sets all components to the
	specified value, overriding any that are explicitly set. Note that if
	ALL is then removed from the config and SIGHUP is issued, all components
	will revert to what is explicitly set, or Default_Log_Level if that is
	specified, or the original log level from the -N command line option
	if that was set, or the code default of EVENT.

	TIRPC is a special component that also sets the active RPC_Debug_Flags.
	If the level for TIRPC is DEBUG or MID_DEBUG, the custom RPC_Debug_Flags
	set by that parameter will be used, otherwise flags will depend on the
	level the TIRPC component is set to:

	NULL or FATAL: 0

	CRIT or MAJ: TIRPC_DEBUG_FLAG_ERROR

	WARN: TIRPC_DEBUG_FLAG_ERROR | TIRPC_DEBUG_FLAG_WARN

	EVENT or INFO: TIRPC_DEBUG_FLAG_ERROR | TIRPC_DEBUG_FLAG_WARN | TIRPC_DEBUG_FLAG_EVENT

	DEBUG or MID_DEBUG: RPC_Debug_Flags

	  Ceph binary

	* name -- optional instance name (equivalent to passing
	  "--name client.rgw.foohost" to the radosgw binary);  the value
	  provided here should be the same as the section name (sans
	  brackets) of the radosgw facility in the Ceph configuration
	  file (which must exist)

	* cluster -- optional cluster name (equivalent to passing
	  "--cluster foo" to any Ceph binary);  use of a non-default
	  value for cluster name is uncommon, but can be verified by
	  examining the startup options of Ceph binaries

	* init_args -- additional argument strings which will be
	  passed verbatim to the radosgw instance startup process as
	  if they had been given on the radosgw command line;  provided
	  for customization in uncommon setups
