cluster/afr: Fail open on split-brain

2018-03-08T06:39:57+00:00

Problem:
Append on a file with split-brain succeeds. Open is intercepted by open-behind,
when write comes on the file, open-behind does open+write. Open succeeds
because afr doesn't fail it. Then write succeeds because write-behind
intercepts it. Flush is also intercepted by write-behind, so the application
never gets to know that the write failed.

Fix:
Fail open on split-brain, so that when open-behind does open+write open fails
which leads to write failure. Application will know about this failure.

cluster/ec: OpenFD heal implementation for EC

2018-02-02T06:50:35+00:00

Existing EC code doesn't try to heal the OpenFD to
avoid unnecessary healing of the data later.

Fix implements the healing of open FDs before
carrying out file operations on them by making an
attempt to open the FDs on required up nodes.

build: make it possible to build cleanly 2x in a row

2017-10-25T11:40:18+00:00

'make clean' does not cleanup everything, and some of the files get
cleaned too eagerly. Several files are being packaged in a 'make dist'
tarball, that get rebuild each time anyway.

Specifically, this change prevents
 - libglusterfs/src/generator.pyc from laying around
 - keeping rpc/xdr/gen/*.x symlinks
 - modifying tests/basic/{fuse,gfapi}/Makefile each run
 - including tests/env.rc and events/src/eventtypes.py in the tarball

gfapi: set lkowner in glfd

2017-10-25T11:33:39+00:00

We need a provision to be able to set lkowner (which is
used to distinguish locks maintained by server) in gfapi.
Since the same lk_owner need to be used to be able to
flush the lock while closing the fd, store the lkowner
in the glfd structure itself.

A new API has been added to be able to set lkowner in glfd.

This is backport of below mainline fix -

glusterd: Gluster should keep PID file in correct location

2017-08-12T13:38:30+00:00

Currently Gluster keeps process pid information of all the daemons
and brick processes in Gluster configuration file directory
(ie., /var/lib/glusterd/*).

These pid files should be seperate from configuration files.
Deletion of the configuration file directory might result into serious problems.
Also, /var/run/gluster is the default placeholder directory for pid files.

So, with this fix Gluster will keep all process pid information of all
processes in /var/run/gluster/* directory.

posix: option to handle the shared bricks for statvfs()

2017-07-31T15:34:58+00:00

Currently 'storage/posix' xlator has an option called option
`export-statfs-size no`, which exports zero as values for few
fields in `struct statvfs`. In a case of backend brick shared
between multiple brick processes, the values of these variables
should be `field_value / number-of-bricks-at-node`. This way,
even the issue of 'min-free-disk' etc at different layers would
also be handled properly when the statfs() sys call is made.

Fixes #241
