On servers that support both NFSv4 and either NFSv2 or NFSv3, both methods will work and give the
same results.
Note
Before Red Hat Enterprise Linux 6 on older NFS servers, depending on how they are
configured, it is possible to export filesystems to NFSv4 clients at different paths. Because
these servers do not enable NFSv4 by default this should not normally be a problem.
9.7.4 . Host name Format s
The host(s) can be in the following forms:
Sin g le mach in e
A fully-qualified domain name (that can be resolved by the server), hostname (that can be
resolved by the server), or an IP address.
Series of mach in es sp ecif ied wit h wild card s
Use the * or ? character to specify a string match. Wildcards are not to be used with IP
addresses; however, they may accidentally work if reverse DNS lookups fail. When
specifying wildcards in fully qualified domain names, dots (. ) are not included in the
wildcard. For example, *. exampl e. co m includes o ne. exampl e. co m but does not
i ncl ud e o ne. two . exampl e. co m.
IP n et wo rks
Use a.b.c.d/z, where a.b.c.d is the network and z is the number of bits in the netmask (for
example 192.168.0.0/24). Another acceptable format is a.b.c.d/netmask, where a.b.c.d is the
network and netmask is the netmask (for example, 192.168.100.8/255.255.255.0).
Net g ro u p s
Use the format @group-name, where group-name is the NIS netgroup name.
9.7.5. NFS over RDMA
To enable the RDMA transport in the linux kernel NFS server, use the following procedure:
Pro ced u re 9 .2. En ab le R DMA f ro m server
1. Ensure the RD MA rpm is installed and the RDMA service is enabled with the following
command:
# yum i nstal l rd ma; chkco nfi g --l evel 234 5 rd ma o n
