47 ing I/O errors. It results in client retry.
48 Drop_Inval_Errors(bool, default false)

60 Path to the directory containing server specific modules
61 Enable_NFS_Stats(bool, default true)
63 Whether to collect perfomance statistics. By default the perfo‐
64 mance counting is enabled. Enable_NFS_Stats can be enabled or
65 disabled dynamically via ganesha_stats.
66 Enable_Fast_Stats(bool, default false)
68 Whether to use fast stats. If enabled this will skip statistics
69 counters collection for per client and per export.
70 Enable_FSAL_Stats(bool, default false)

73 tics. Enable_FSAL_Stats can be enabled or disabled dynamically

88 requested by NFS clients. Enable_CLNT_AllOps_Stats can be en‐
89 abled or disabled dynamically via ganesha_stats.
90 Short_File_Handle(bool, default false)
92 Whether to use short NFS file handle to accommodate VMware NFS
93 client. Enable this if you have a VMware NFSv3 client. VMware
94 NFSv3 client has a max limit of 56 byte file handles.

108 Protocols(enum list, default [3,4,9P])
110 Possible values:
112 3, 4, NFS3, NFS4, V3, V4, NFSv3, NFSv4, 9P
113 The protocols that Ganesha will listen for. This is a hard
115 limit, as this list determines which sockets are opened. This
116 list can be restricted per export, but cannot be expanded.
117 NSM_Use_Caller_Name(bool, default false)
119 Whether to use the supplied name rather than the IP address in
120 NSM operations.
121 Clustered(bool, default true)
123 Whether this Ganesha is part of a cluster of Ganeshas. Its ven‐
124 dor specific option.
125 fsid_device(bool, default false)
127 Whether to use device major/minor for fsid.
128 mount_path_pseudo(bool, default false)
130 Whether to use Pseudo (true) or Path (false) for NFS v3 and 9P
131 mounts.
132 This option defaults to false for backward compatibility, how‐
134 ever, for new setups, it's strongly recommended to be set true
135 since it then means the same server path for the mount is used
136 for both v3 and v4.x.
137 Dbus_Name_Prefix
139 DBus name prefix. Required if one wants to run multiple ganesha
140 instances on single host. The prefix should be different for ev‐
141 ery ganesha instance. If this is set, the dbus name will be
142 <prefix>.org.ganesha.nfsd
143 Enable_UDP(bool, default true)
145 Whether to create UDP listeners for NFS, NLM, RQUOTA, and regis‐
146 ter them with portmapper. Set to false, e.g., to run as
147 non-root.
148 Max_Uid_To_Group_Reqs(uint32, range 0 to INT32_MAX, default 0)
150 Maximum number of concurrent uid2grp requests that can be made
151 by ganesha. In environments with a slow Directory Service
152 Provider, where users are part of large number of groups, and
153 Manage_Gids is set to True, uid2grp queries made by ganesha can
154 fail if a large number of them are made in parallel. This option
155 throttles the number of concurrent uid2grp queries that ganesha
156 makes.
