build: use standard PKG_CHECK_MODULES for libxml2 availability

2018-08-16T06:55:21+00:00

In case the development parts of libxml2 are not installed, it was
required to re-run ./autogen.sh to cleanup the cached values for the
check. This is not nice towards users. By using the standard
PKG_CHECK_MODULES for libxml-2.0 the results of the check are not cached
and will be probed again when running ./configure.

build: add --without-server option

2018-02-19T17:38:55+00:00

With Gluster 4.0 we will not provide the server components for EL6 and
older. At one point Gluster 4.x will get GlusterD2, which requires
Golang tools in the distribution. EL6 does not contain these at the
moment.

With this change, it is possible to `./configure --without-server` which
prevents building glusterd and the xlators for the bricks. Building RPMs
can pass `--without server` and the glusterfs-server sub-package will
not be created.

build: conditionally build legacy gNFS server and associated sub-packaging

2017-04-28T14:08:41+00:00

Plus some additional logic in glusterd to ensure gnfs (glusterfs)
daemons are never started if server/nfs xlator is not installed.

As a service, nfs is still initialized. The glusterfs-gnfs RPM
may be installed or uninstalled independent of anything else,
including on a system where gluster is actively running, so the
existence of the xlator is always tested before trying to start
gnfs.

glusterd: (storhaug) remove ganesha

2017-03-21T17:13:44+00:00

remove all vestiges of ganesha

The storhaug CLI is used to manage ganesha and Samba. Also any setup
and teardown of the ganesha HA is initiated using storhaug to preserve
the proper layering.

build/packaging: Debian and Ubuntu don't have /usr/libexec

2017-03-13T14:18:07+00:00

GLUSTERFS_LIBEXECDIR is effectively hard-coded to /usr/libexec/glusterfs
in configure(.ac)

Debian-based distributions don't have a /usr/libexec/ directory

This issues is partially mitigated by the use of $libexecdir in
some of the Makefile.am files, but even so the incorrectly defined
GLUSTERFS_LIBEXECDIR results in various things such as gsyncd,
glusterfind, eventsd, etc., trying to invoke other scripts and
programs from a location that doesn't exist.

And once we correctly define GLUSTERFS_LIBEXECDIR, then we might as
well use it appropriatedly.

tier : Tier as a service

2017-01-17T04:49:47+00:00

tierd is implemented by separating from rebalance process.

The commands affected:

1) Attach tier will trigger this process instead of old one
2) tier start and tier start force will also trigger this process.
3) volume status [tier] will show tier daemon as a process instead
of task and normal tier status and tier detach status works.
4) tier stop implemented.
5) detach tier implemented separately along with new detach tier
status
6) volume tier volname status will work using the changes.
7) volume set works

This patch has separated the tier translator from the legacy
DHT rebalance code. It now sends the RPCs from the CLI
to glusterd separate to the DHT rebalance code.
The daemon is now a service, similar to the snapshot daemon,
and can be viewed using the volume status command.

The code for the validation and commit phase are the same
as the earlier tier validation code in DHT rebalance.

The “brickop” phase has been changed so that the status
command can use this framework.

The service management framework is now used.
DHT rebalance does not use this framework.

This service framework takes care of :

*) spawning the daemon, killing it and other such processes.
*) volume set options , which are written on the volfile.
*) restart and reconfigure functions. Restart is to restart
the daemon at two points
        1)after gluster goes down and comes up.
        2) to stop detach tier.
*) reconfigure is used to make immediate volfile changes.
By doing this, we don’t restart the daemon.
it has the code to rewrite the volfile for topological
changes too (which comes into place during add and remove brick).

With this patch the log, pid, and volfile are separated
and put into respective directories.

glusterd/quota: upgrade quota.conf file during an upgrade

2016-11-08T04:37:05+00:00

Problem
=======
When quota is enabled on 3.6, it will have quota conf version in quota.conf
as v1.1. This node gets upgraded to 3.7 but it will still have quota conf
version as v1.1 until a quota enable/disable/set limit is initiated. When
this is not initiated and when this node tries to peer probe a node which
is a fresh install of 3.7 (which will have quota conf version as v1.2), then this
will result in "Peer rejected" state. This patch fixes the issue.

Solution
========
When an upgrade happens from 3.6 to 3.7, quota.conf file needs
to be modified as well. With 3.6, in quota.conf the version will be
v1.1 and it needs to be changed to v1.2 from 3.7. This is because in
3.7, inode quota feature is introduced. So when an op-version bumpup
happens quota.conf needs to be upgraded with quota conf version v1.2
and all the 16 byte uuid needs to be changed to 17 bytes uuid as well.

Previously, when the cluster version is upgraded to 3.7, the quota.conf
got upgraded as well. But, the upgradation was done only when quota
enable/disable/set limit is done. With this patch, the upgradation is done
during a cluster op version bump up as well.

build: out-of-tree builds generates files in the wrong directory

2016-09-18T16:34:37+00:00

And minor cleanup of a few of the Makefile.am files while we're
at it.

Rewrite the make rules to do what xdrgen does. Now we can get rid
of xdrgen.

Note 1. netbsd6's sed doesn't do -i. Why are we still running
smoke tests on netbsd6 and not netbsd7? We barely support netbsd7
as it is.

Note 2. Why is/was libgfxdr.so (.../rpc/xdr/src/...) linked with
libglusterfs? A cut-and-paste mistake? It has no references to
symbols in libglusterfs.

Note3. "/#ifndef\|#define\|#endif/" (note the '\'s) is a _basic_
regex that matches the same lines as the _extended_ regex
"/#(ifndef|define|endif)/". To match the extended regex sed needs to
be run with -r on Linux; with -E on *BSD. However NetBSD's and
FreeBSD's sed helpfully also provide -r for compatibility. Using a
basic regex avoids having to use a kludge in order to run sed with
the correct option on OS X.

Note 4. Not copying the bit of xdrgen that inserts copyright/license
boilerplate. AFAIK it's silly to pretend that machine generated
files like these can be copyrighted or need license boilerplate.
The XDR source files have their own copyright and license; and
their copyrights are bound to be more up to date than old
boilerplate inserted by a script. From what I've seen of other
Open Source projects -- e.g. gcc and its C parser files generated
by yacc and lex -- IIRC they don't bother to add copyright/license
boilerplate to their generated files.

It appears that it's a long-standing feature of make (SysV, BSD,
gnu) for out-of-tree builds to helpfully pretend that the source
files it can find in the VPATH "exist" as if they are in the $cwd.
rpcgen doesn't work well in this situation and generates files
with "bad" #include directives.

E.g. if you `rpcgen ../../../../$srcdir/rpc/xdr/src/glusterfs3-xdr.x`,
you get an #include directive in the generated .c file like this:

  ...
  #include "../../../../$srcdir/rpc/xdr/src/glusterfs3-xdr.h"
  ...

which (obviously) results in compile errors on out-of-tree build
because the (generated) header file doesn't exist at that location.
Compared to `rpcgen ./glusterfs3-xdr.x` where you get:

  ...
  #include "glusterfs3-xdr.h"
  ...

Which is what we need. We have to resort to some Stupid Make Tricks
like the addition of various .PHONY targets to work around the VPATH
"help".

Warning: When doing an in-tree build, -I$(top_builddir)/rpc/xdr/...
looks exactly like -I$(top_srcdir)/rpc/xdr/...  Don't be fooled though.
And don't delete the -I$(top_builddir)/rpc/xdr/... bits
