nfsd: allow server scope to be set with config or command line.nfs-utils-2-6-3-rc4
NFSv4.1 and later require the server to report a "scope". Servers with
the same scope are expected to understand each other's state ids etc,
though may not accept them - this ensure there can be no
misunderstanding. This is helpful for migration.
Servers with different scope are known to be different and if a server
appears to change scope on a restart, lock recovery must not be
attempted.
It is important for fail-over configurations to have the same scope for
all server instances. Linux NFSD sets scope to host name. It is common
for fail-over configurations to use different host names on different
server nodes. So the default is not good for these configurations and
must be over-ridden.
As discussed in
https://github.com/ClusterLabs/resource-agents/issues/1644
some HA management tools attempt to address this with calls to "unshare"
and "hostname" before running "rpc.nfsd". This is unnecessarily
cumbersome.
This patch adds a "-S" command-line option and nfsd.scope config value
so that the scope can be set easily for nfsd.
