9 nfsserver [start | stop | monitor | meta-data | validate-all]
10
12 Nfsserver helps one to manage the Linux nfs server as a failover-able
13 resource in Linux-HA. It depends on Linux specific NFS implementation
14 details, so is considered not portable to other platforms yet.
15
17 nfs_init_script
18 The default init script shipped with the Linux distro. The
19 nfsserver resource agent offloads the start/stop/monitor work to
20 the init script because the procedure to start/stop/monitor
21 nfsserver varies on different Linux distro. In the event that this
22 option is not set, this agent will attempt to use an init script at
23 this location, /etc/init.d/nfsserver, or detect a systemd unit-file
24 to use in the event that no init script is detected.
25 (optional, string, default "auto detected")
27 nfs_no_notify
29 Do not send reboot notifications to NFSv3 clients during server
30 startup.
31 (optional, boolean, default false)
33 nfs_notify_foreground
35 Keeps the sm-notify attached to its controlling terminal and
36 running in the foreground.
37 (optional, boolean, default false)
39 nfs_smnotify_retry_time
41 Specifies the length of sm-notify retry time, in minutes, to
42 continue retrying notifications to unresponsive hosts. If this
43 option is not specified, sm-notify attempts to send notifications
44 for 15 minutes. Specifying a value of 0 causes sm-notify to
45 continue sending notifications to unresponsive peers until it is
46 manually killed.
47 (optional, integer, no default)
49 nfs_server_scope
51 RFC8881, 8.4.2.1 State Reclaim:
52 If the server scope is different, the client should not attempt to
54 reclaim locks. In this situation, no lock reclaim is possible. Any
55 attempt to re-obtain the locks with non-reclaim operations is
56 problematic since there is no guarantee that the existing
57 filehandles will be recognized by the new server, or that if
58 recognized, they denote the same objects. It is best to treat the
59 locks as having been revoked by the reconfiguration event.
60 For lock reclaim to even be attempted, we have to define and set
62 the same server scope for NFSD on all cluster nodes in the NFS
63 failover cluster.
64 This agent won't "guess" a suitable server scope name for you, you
66 need to explicitly specify this. But without it, NFSv4 lock reclaim
67 after failover won't work properly. Suggested value: the failover
68 "service IP".
69 (optional, string, no default)
71 nfs_ip
73 Comma separated list of floating IP addresses used to access the
74 nfs service
75 (optional, string, no default)
77 nfs_shared_infodir
79 The nfsserver resource agent will save nfs related information in
80 this specific directory. And this directory must be able to
81 fail-over before nfsserver itself.
82 (optional, string, no default)
84 rpcpipefs_dir
86 The mount point for the sunrpc file system. Default is
87 /var/lib/nfs/rpc_pipefs. This script will mount (bind)
88 nfs_shared_infodir on /var/lib/nfs/ (cannot be changed), and this
89 script will mount the sunrpc file system on /var/lib/nfs/rpc_pipefs
90 (default, can be changed by this parameter). If you want to move
91 only rpc_pipefs/ (e.g. to keep rpc_pipefs/ local) from default,
92 please set this value.
93 (optional, string, default "/var/lib/nfs/rpc_pipefs")
95 nfsd_args
97 Specifies what arguments to pass to the nfs daemon on startup. View
98 the rpc.nfsd man page for information on what arguments are
99 available. Note that setting this value will override all settings
100 placed in the local /etc/sysconfig/nfs file.
101 (optional, string, no default)
103 lockd_udp_port
105 The udp port lockd should listen on. Note that setting this value
106 will override all settings placed in the local /etc/sysconfig/nfs
107 file.
108 (optional, integer, no default)
110 lockd_tcp_port
112 The tcp port lockd should listen on. Note that setting this value
113 will override all settings placed in the local /etc/sysconfig/nfs
114 file.
115 (optional, integer, no default)
117 statd_outgoing_port
119 The source port number sm-notify uses when sending reboot
120 notifications. Note that setting this value will override all
121 settings placed in the local /etc/sysconfig/nfs file.
122 (optional, integer, no default)
124 statd_port
126 The port number used for RPC listener sockets. Note that setting
127 this value will override all settings placed in the local
128 /etc/sysconfig/nfs file.
129 (optional, integer, no default)
131 mountd_port
133 The port number used for rpc.mountd listener sockets. Note that
134 setting this value will override all settings placed in the local
135 /etc/sysconfig/nfs file.
136 (optional, integer, no default)
138 rquotad_port
140 The port number used for rpc.rquotad. Note that setting this value
141 will override all settings placed in the local /etc/sysconfig/nfs
142 file.
143 (optional, integer, no default)

147 This resource agent supports the following actions (operations):
148 start
150 Starts the resource. Suggested minimum timeout: 40s.
151 stop
153 Stops the resource. Suggested minimum timeout: 20s.
154 monitor
156 Performs a detailed status check. Suggested minimum timeout: 20s.
157 Suggested interval: 10s.
158 meta-data
160 Retrieves resource agent metadata (internal use only). Suggested
161 minimum timeout: 5s.
162 validate-all
164 Performs a validation of the resource configuration. Suggested
165 minimum timeout: 30s.
166
168 The following is an example configuration for a nfsserver resource
169 using the crm(8) shell:
170 primitive p_nfsserver ocf:heartbeat:nfsserver \
172 op monitor depth="0" timeout="20s" interval="10s"
173
175 The following is an example configuration for a nfsserver resource
176 using pcs(8)
177 pcs resource create p_nfsserver ocf:heartbeat:nfsserver \
179 op monitor OCF_CHECK_LEVEL="0" timeout="20s" interval="10s"
