6 ocf_heartbeat_exportfs - Manages NFS exports

9 exportfs [start | stop | monitor | meta-data | validate-all]
10
12 Exportfs uses the exportfs command to add/remove nfs exports. It does
13 NOT manage the nfs server daemon. It depends on Linux specific NFS
14 implementation details, so is considered not portable to other
15 platforms yet.
16
18 clientspec
19 The client specification allowing remote machines to mount the
20 directory (or directories) over NFS.
21
22 Note: it follows the format defined in "man exportfs". For example,
23 in the use case to export the directory(-ies) for multiple subnets,
24 please do config a dedicated primitive for each subnet CIDR ip
25 address, and do not attempt to use multiple CIDR ip addresses in a
26 space separated list, like in /etc/exports.
27
28 (required, string, no default)
29
30 options
31 The options to pass to exportfs for the exported directory or
32 directories.
33
34 (optional, string, no default)
35
36 directory
37 The directory or directories to be exported using NFS. Multiple
38 directories are separated by white space.
39
40 (required, string, no default)
41
42 fsid
43 The fsid option to pass to exportfs. This can be a unique positive
44 integer, a UUID (assuredly sans comma characters), or the special
45 string "root" which is functionally identical to numeric fsid of 0.
46 If multiple directories are being exported, then they are assigned
47 ids sequentially starting with this fsid (fsid, fsid+1, fsid+2,
48 ...). Obviously, in that case the fsid must be an integer. 0 (root)
49 identifies the export as the root of an NFSv4 pseudofilesystem --
50 avoid this setting unless you understand its special status. This
51 value will override any fsid provided via the options parameter.
52
53 (required, string, no default)
54
55 unlock_on_stop
56 Relinquish NFS locks associated with this filesystem when the
57 resource stops. Enabling this parameter is highly recommended
58 unless the path exported by this exportfs resource is also exported
59 by a different resource.
60
61 Note: Unlocking is only possible on Linux systems where
62 /proc/fs/nfsd/unlock_filesystem exists and is writable. If your
63 system does not fulfill this requirement (on account of having an
64 nonrecent kernel, for example), you may set this parameter to 0 to
65 silence the associated warning.
66
67 (optional, boolean, default 1)
68
69 wait_for_leasetime_on_stop
70 When stopping (unexporting), wait out the NFSv4 lease time. Only
71 after all leases have expired does the NFS kernel server relinquish
72 all server-side handles on the exported filesystem. If this
73 exportfs resource manages an export that resides on a mount point
74 designed to fail over along with the NFS export itself, then
75 enabling this parameter will ensure such failover is working
76 properly. Note that when this parameter is set, your stop timeout
77 MUST accommodate for the wait period. This parameter is safe to
78 disable if none of your NFS clients are using NFS version 4 or
79 later.
80
81 (optional, boolean, default 0)
82
83 rmtab_backup
84 Back up those entries from the NFS rmtab that apply to the exported
85 directory, to the specified backup file. The filename is
86 interpreted as relative to the exported directory. This backup is
87 required if clients are connecting to the export via NFSv3 over
88 TCP. Note that a configured monitor operation is required for this
89 functionality.
90
91 To disable rmtab backups, set this parameter to the special string
92 "none".
93
94 (optional, string, default ".rmtab")
95
97 This resource agent supports the following actions (operations):
98
99 start
100 Starts the resource. Suggested minimum timeout: 40s.
101
102 stop
103 Stops the resource. Suggested minimum timeout: 120s.
104
105 monitor
106 Performs a detailed status check. Suggested minimum timeout: 20s.
107 Suggested interval: 10s.
108
109 meta-data
110 Retrieves resource agent metadata (internal use only). Suggested
111 minimum timeout: 5s.
112
113 validate-all
114 Performs a validation of the resource configuration. Suggested
115 minimum timeout: 30s.
116
118 The following is an example configuration for a exportfs resource using
119 the crm(8) shell:
120
121 primitive p_exportfs ocf:heartbeat:exportfs \
122 params \
123 clientspec=string \
124 directory=string \
125 fsid=string \
126 op monitor depth="0" timeout="20s" interval="10s"
127
129 The following is an example configuration for a exportfs resource using
130 pcs(8)
131
132 pcs resource create p_exportfs ocf:heartbeat:exportfs \
133 clientspec=string \
134 directory=string \
135 fsid=string \
136 op monitor depth="0" timeout="20s" interval="10s"
