* logger: support logdir choosing via Environment variablePrasanna Kumar Kalever2017-08-171-22/+0
| | | | | | | | | | | | Currently the default logdir is DATADIR /log/gluster-block/ This patch will provide a way to change this default logdir via Env variable $ export GB_LOGDIR=/var/log/gluster-block-new-path/ Note: make sure to restart the processes (cli & daemon) after you set GB_LOGDIR Change-Id: Id142e4a4dfe7b6ebc9cf8296b8ceb8bff37691b8 Signed-off-by: Prasanna Kumar Kalever <prasanna.kalever@redhat.com>

* logging: redirect configshell logs to GB_LOGDIRPrasanna Kumar Kalever2017-04-131-14/+17
| | | | | | | | | | | | | | | | | | | | currently, GLOBAL CONFIG GROUP =================== [...] logfile=hello ------------- Logfile to use. [...] i.e. configshell logs are collected at 'hello' file. This patch will redirect configshell logs to 'GB_LOGDIR/gluster-block-configshell.log' Change-Id: I487c6197578c24412fbec72cb8c354725614de59 Fixes: #13 Signed-off-by: Prasanna Kumar Kalever <prasanna.kalever@redhat.com>
* lockfile: don't allow multiple instances of daemon to runPrasanna Kumar Kalever2017-02-211-1/+2
| | | | | | | | | | | | | | 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.

* gluster-block: create block files in '/block-store' dirPrasanna Kumar Kalever2017-02-081-0/+4
| | | | | | | | | | | | | | | | | till now we have '/block-meta' dir for meta files and actual block files used to reside in '/' dir. From now, lets place block files in '/block-store' So, this is how it looks like: $ tree /mnt/ /mnt/ ├── block-meta │   ├── meta.lock │   └── TARGET └── block-store └── 103e4cf1-bf41-404a-9fe1-b7c70fc33b3e Signed-off-by: Prasanna Kumar Kalever <prasanna.kalever@redhat.com>
* gluster-block: migrate build to libtoolz and create rpmPrasanna Kumar Kalever2017-02-071-0/+26
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>
