* gluster-blockd: use SO_REUSEADDR on bindVijay Bellur2017-05-191-0/+7
| | | | | | | | | | | | | | Currently immediate restarts of gluster-blockd failsi with: [1495181620] ERROR: bind on port 24006 failed (Address already in use) Since the closed socket connection is still in TIME_WAIT on 24006 This patch sets socket option SO_REUSEADDR, which allows gluster-blockd to bind even if socket is in a TIME_WAIT state.

* build: use rpcgen to generate all XDR codeNiels de Vos2017-03-172-3/+5
| | | | | | | | | | | | | | | | | | | | | Remove all generated files and have them generated when needed. This build a libgbrpcxdr.la archive with the .o files that gets linked into the libgbrpc.la archive. 'rpcgen' generates .c code that triggers warnings for various compilers. This is not something that can easily be fixed, so add rpc-pragmas.h (like GlusterFS does) to prevent these warnings. There are some functions used by gluster-blockd.c that are not part of the header and were manually added to block.h. Because block.h get regenerated now, these functions have been added to a new file block_svc.h. Note that generated and compiled files land in $(top_builddir). This directory does not need to be the same as $(top_srcdir). Change-Id: I0e764d159d6d785699537eed4e24b16883218038 Fixes: #2 Signed-off-by: Niels de Vos <ndevos@redhat.com>
* lockfile: don't allow multiple instances of daemon to runPrasanna Kumar Kalever2017-02-211-6/+36
| | | | | | | | | | | | | | until now there is no check to defend on multiple runs of daemon within the same node. This patch takes a non blocking lock on 'gluster-blockd.lock' file, if it succeeds only then daemon is allowed to run, if there is already a lock on lock-file (taken by some other instance of gluster-blockd) we will exit. This patch also renames GB_UNIX_ADDRESS from gluster-block.socket to gluster-blockd.socket, as that makes better sense.

* cli: cart off unwanted output from create commandPrasanna Kumar Kalever2017-02-151-1/+1
| | | | | | | | | | | | | | The response of below sub-operations as part of create are undesired $ targetcli set global auto_add_default_portal=false $ targetcli / saveconfig $ targetcli set attributes generate_node_acls=1 demo_mode_write_protect=0 Hence redirecting them to '/dev/null' This patch also fix a bug in the previous patch i.e. missed inverting [!] function return in if() Signed-off-by: Prasanna Kumar Kalever <prasanna.kalever@redhat.com>

* gluster-block: migrate build to libtoolz and create rpmPrasanna Kumar Kalever2017-02-072-0/+132
Till now we had simple makefile for checking dependencies and building. Using libtoolz will give more control on dependency checks and flexibility. This patch also introduce rpm build feature. Compiling: $ ./autogen.sh $ ./configure $ make -j $ make install Building RPMS: $ make rpms Running: $ systemctl start gluster-blockd.service Using CLI: $ gluster-block help Signed-off-by: Prasanna Kumar Kalever <prasanna.kalever@redhat.com>
