cluster/afr: Make read child match check in afr optional

2015-03-18T11:21:28+00:00

        Backport of: http://review.gluster.org/#/c/9917

Having this particular check which was introduced by
commit bb2df4e63fa8a5d65f18b4a5efc757e8d475fbff causes a drop in
performance in readdirp. So the behavior is made configurable with this
patch.

glusterd: pass the bind-address to starting services

2014-10-21T15:38:50+00:00

When the transport.socket.bind-address option is set to a hostname or
ip-address, the services started by GlusterD fail to connect to the
management daemon. GlusterD always forces the services to connect to the
"localhost" hostname, even if it is not listening on that address.

GlusterD should take the transport.socket.bind-address option into
consideration, and pass that to the glusterfs-clients with the -s or
--volfile commandline parameter.

Note that this is not a change that removes all hard-coded dependencies
on "localhost". This change merely makes it possible to start required
services when the transport.socket.bind-address option is set.

glusterd: make bricks respect 'transport.socket.bind-address'

2014-10-21T15:38:18+00:00

When GlusterD starts the brick processes, these will listen on all
interfaces. When the 'transport.socket.bind-address' option is set in
glusterd.vol, the brick processes should only listen on the specified
hostname or IP-address.

glusterd/quota: Heal pgfid xattr on existing data when the quota is

2014-10-20T16:13:34+00:00

enable

        Backport of: http://review.gluster.org/8878

The pgfid extended attributes are used to construct the ancestry path
(from the file to the volume root) for nameless lookups on files.
As NFS relies on nameless lookups heavily, quota enforcement through NFS
would be inconsistent if quota were to be enabled on a volume with
existing data.

Solution is to heal the pgfid extended attributes as a part of lookup
perfomed by quota-crawl process. In a posix lookup check for pgfid xattr
and if it is missing set the xattr.

xlators/mgmt: don't allow glusterd fork bomb (cache the brick inode size)

2014-08-15T16:46:16+00:00

Was don't leave zombies if required programs aren't installed

Also, the existing if (strcmp (foo, bar) == 0) antipattern leaves me
underwhelmed -- table driven is better;

I like fully qualified paths to system tools too.

File systems aren't going to change their inode size. Rather than
fork-and-exec a tool repeatedly, hang on to the answer for subsequent
use. Even if there are hundreds of volumes the size of a dict to keep
this in memory is small.
