nfs: do not fail to start when optional RPC-programs fail to register

2015-03-26T10:05:56+00:00

Some RPC-programs are not strictly required for the NFS-server. When
these optional protocols fail to get registered at the portmapper, there
is no need to fail the starting of the NFS-server.

Required RPC-programs:
 - NFS
 - MNT

Optional RPC-programs:
 - NLM
 - ACL

gNFS: Export / Netgroup authentication on Gluster NFS mount

2015-03-15T14:01:38+00:00

* Parses linux style export file/netgroups file into a structure that
  can be lookedup.

* This parser turns each line into a structure called an "export
  directory". Each of these has a dictionary of hosts and netgroups
  which can be looked up during the mount authentication process.
  (See Change-Id Ic060aac and I7e6aa6bc)

* A string beginning withan '@' is treated as a netgroup and a string
  beginning without an @ is a host.
  (See Change-Id Ie04800d)

* This parser does not currently support all the options in the man page
  ('man exports'), but we can easily add them.

nfs: add auth-cache for the MOUNT protocol

2015-03-15T13:40:22+00:00

Authentication cache for the new fine grained contol for the MOUNT
protocol. The extended authentication (see Change-Id Ic060aac) benefits
from caching the access/permission checks that are done when an
NFS-client mounts an export.

This auth-cache will be used by Change-Id I181e8c1.

nfs: add support for separate 'exports' file

2015-03-15T07:45:50+00:00

The Linux kernel NFS server uses /etc/exports to manage permissions for
the NFS-clients. Extending the Gluster/NFS server to support a similar
scheme is needed for many deployments in enterprise environments.

gNFS: RFE for NFS connection behavior

2013-11-15T00:07:02+00:00

Implement reconfigure() for NFS xlator so that volume set/reset wont
restart the NFS server process. But few options can not be reconfigured
dynamically e.g. nfs.mem-factor, nfs.port etc which needs NFS to be
restarted.

nfs: persistent caching of connected NFS-clients

2013-08-28T13:54:44+00:00

Introduce /var/lib/glusterfs/nfs/rmtab to contain a list of NFS-clients
which have a volume mounted. The volume option 'nfs.mount-rmtab' can be
set to an alternative filename. When the file is located on shared
storage, multiple gNFS servers can use the same file to present a single
NFS-server.

This cache is read when a system administrator calls 'showmount -a' and
updated when an NFS-client calls MNT or UMNT from the MOUNT protocol.

Usage:
- create a volume for storing the shared rmtab file
- mount the volume on all storage servers, at the same location
- make sure that the volume is mounted at boot (add to /etc/fstab)
- place the rmtab file on the volume:
   # gluster volume set  nfs.mount-rmtab /
- any subsequent mount requests will add an entry to this file
- 'showmount -a' requests will return the NFS-clients using the cluster

Note:
The NFS-server does currently not support reconfigure(). When a
configuration option is set/changed, the NFS-server glusterfs process
gets restarted. This causes the active NFS-clients to be forgotten (the
entries are saved in the old rmtab, but we do not have a reference to
that file any more, so we can't re-add them). Therefor a re-mount done
by the NFS-clients is needed before they get listed in the rmtab again.

would occur if we were using native protocol, and return proper status if
the self-heal fails.  Best of all, we don't need to misrepresent times.
