glusterfsd: glusterfs_ctx_defaults_init should not re-initialize ctx->locks

2016-12-02T06:23:38+00:00

glusterfs_ctx_new already initialize ctx->locks therefore the second
initialization in glusterfs_ctx_defaults_init does not make sense.

glusterfsd: Continuous errors are getting in mount logs while glusterd is down

2016-11-10T14:45:19+00:00

Problem: when glusterd is down, getting the continuous mgmt_rpc_notify errors
         messages in the volume mount log for every 3 seconds,it will
         consume disk space.

Solution: To reduce the frequency of error messages use GF_LOG_OCCASIONALLY.

glusterfsd/main: fix OOM adjustment for older kernels

2016-10-11T12:18:05+00:00

Milind Changire reported that GlusterFS fails to build on RHEL5
because linux/oom.h is unavailable.

Milind's initial patch disables OOM adjustment completely
for those environments that do not have this header. However,
I'd take another approach that:

1) checks for linux/oom.h in compile-time and defines necessary
constants if the header is not present;
2) checks for available OOM API in /proc in run-time and uses it
accordingly.

This allows OOM to be adjusted properly on RHEL5 (the kernel is pretty new
to present /proc API for that) as well as RHEL6 (the kernel has many thing
backported including new /proc API).

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

http://review.gluster.org/14085 fixes a/the "leak" - via the

However 14085 won't pass the smoke test until all the warnings are

feature/bitrot: Ondemand scrub option for bitrot

2016-08-25T21:39:38+00:00

The bitrot scrubber takes 'hourly/daily/biweekly/monthly'
as the values for 'scrub-frequency'. There is no way
to schedule the scrubbing when the admin wants it.

Ondemand scrubbing brings in the new option 'ondemand'
with which the admin can start scrubbing ondemand.
It starts the scrubbing immediately.

Ondemand scrubbing is successful only if the scrubber
is in 'Active (Idle)' (waiting for it's next frequency
cycle to start scrubbing). It is not entertained when
the scrubber is in 'Paused' or already running.

Here is the command line syntax.

gluster volume bitrot  scrub ondemand

mgmt: remove unused and misleading pmap_signup

2016-07-08T04:26:26+00:00

We use signin, but not signup.  Having both just introduces confusion.
The proc number has been retained to avoid changes to the numbering of
other procs, and the mapping to a name has similarly been retained as a
placeholder, but the code and structure definitions have been removed.
