* gluster-block: threadify remote requestsPrasanna Kumar Kalever2017-02-091-3/+3
| | | | | | | | | | | | | | | Before: ------ rpc clnt_call() is synchronous, for a multipath request each remote call has to wait until the previous remote call returns i,e each remote op happens in serial. After: ----- As we now threadify the remote calls, all the remote call's happens in parallel shrinking the overall latency for create and delete requests.

* gluster-block: create block files in '/block-store' dirPrasanna Kumar Kalever2017-02-081-10/+62
| | | | | | | | | | | | | | | | | 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>

| | | | | | | There were two glfs_init(and friends) invocations per op (create & delete). This patch just unifies those calls (since they anyway belong to same volume) Signed-off-by: Prasanna Kumar Kalever <prasanna.kalever@redhat.com>
* gluster-block: migrate build to libtoolz and create rpmPrasanna Kumar Kalever2017-02-071-0/+270
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>
