nfsrahead is configured in /etc/nfs.conf, in the section titled nfsrahead. It accepts the following configurations. nfs=<value> The readahead value applied to NFSv3 mounts. nfs4=<value> The readahead value applied to NFSv4 mounts. default=<value> The default configuration when none of the configurations above is set.

nfsrahead is a tool intended to be used with udev to set the read_ahead_kb parameter of NFS mounts, according to the configuration file (see CONFIGURATION). device is the device number for the NFS backing device as provided by the kernel.

[nfsrahead] nfs=15000 # readahead of 15000 for NFSv3 mounts nfs4=16000 # readahead of 16000 for NFSv4 mounts default=128 # default is 128
