of readdirp

protocol: increase default group-cache-timeout to 300 seconds

2015-05-06T17:34:22+00:00

sssd uses 300 seconds by default too. There is no need to overload sssd
with requests that it would have cached.

nfs: make it possible to disable nfs.mount-rmtab

2015-05-03T18:16:09+00:00

When there are many NFS-clients doing very often mount/unmount actions,
the updating of the 'rmtab' can become a bottleneck and cause delays. In
these situations, the output of 'showmount' may be less important than
the responsiveness of the (un)mounting.

By setting 'nfs.mount-rmtab' to the value "/-", the cache file is not
updated anymore, and the entries are only kept in memory.

nfs: Enable throttling for rpcsvc

2015-05-03T18:08:11+00:00

Busy nfs servers need throttling to prevent duplicate requests
from casuing an increase in memory consumption.

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

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

NFS-Ganesha: Volume set option for managing NFS-Ganesha exports.

2015-03-18T08:53:22+00:00

A dummy translator has been introduced as a place
holder for functions related to managing NFS-Ganesha
exports. A volume set option is introduced to
manage volume level exports.

gluster vol set  ganesha.enable ON/OFF

1. gluster volume set  ganesha.enable ON

It creates the export config file with a unique export ID.
Sends a DBus signal to export this volume dynamically.

2. gluster vol set  ganesha.enable OFF

Unexports the specific volume. Deletes the specfic
config file related to the volume.

This change also removes the handling of the older
keys "nfs-ganesha.enable" and "nfs-ganesha.host"

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.

rdma :mount fails for nfs protocol in rdma volumes

2014-11-19T09:44:54+00:00

When we mount rdma only volume or tcp,rdma volume using newly
peer probed IP's(nfs-server on new nodes) through nfs protocol,
mount fails for rdma only volume and mount happens with
help of tcp protocol in the case of tcp,rdma volumes. That is for
newly added servers will always get transport type as "socket".
This is due to nfs_transport_type is exported correctly and
imported wrongly.

This can be verified by the following ,
   * Create a rdma only volume or tcp,rdma volume
   * Add a new server into the trusted pool.
   * Checkout the client transport type specified nfs-server
     volgraph.It will be always tcp(socket type) instead of rdma.
   * And also for rdma only volume in the nfs log, we can see
     'connection refused' message for every reconnect between
     nfs server and glusterfsd.
