* build: pass "--with systemd" to rpmbuild if neededNiels de Vos2017-02-251-0/+5
| | | | | | | | | | | In case ./configure detects that the environment is using systemd, the "make install" step will copy the gluster-block.service file to the right location. However, the RPMs do not include this file by default, so adding a "--with systemd" to rpmbuild/mock is needed (until there is some form of auto-detection in the .spec).

* build: cleaner build RPMs with "make rpms"Niels de Vos2017-02-251-8/+10
| | | | | | | | | | | | There is no need to copy all the files everywhere, this can be controlled with --define options to rpmbuild. Also add a "make srpm" target for building the source RPM that can then be built with 'mock' or uploaded to build systems from different distributions.

* cli: change in synopsis for gluster-block commandsPrasanna Kumar Kalever2017-02-245-231/+161
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | from now we will have fixed formats for commands. The new outfit will look like: $ gluster-block help gluster-block (3ba7ec5) usage: gluster-block <command> <volname[/blockname]> [<args>] commands: create <volname/blockname> [ha <count>] <host1[,host2,...]> <size> create block device. list <volname> list available block devices. info <volname/blockname> details about block device. delete <volname/blockname> delete block device. help show this message and exit. version show version info and exit. Example usage: $ gluster-block create volume/blockname 192.168.0.1 1GiB $ gluster-block create volume/blockname ha 2 192.168.0.1,192.168.0.2 1GiB $ gluster-block list volume $ gluster-block info volume/blockname $ gluster-block delete volume/blockname Change-Id: Idc6b55c26432ed1ac3f002c2a2b3dbb81b180ec2 Signed-off-by: Prasanna Kumar Kalever <prasanna.kalever@redhat.com>
* lockfile: don't allow multiple instances of daemon to runPrasanna Kumar Kalever2017-02-212-7/+38
| | | | | | | | | | | | | | 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-blockd: defend on connect() issuesPrasanna Kumar Kalever2017-02-202-12/+31
| | | | | | | | | | | | | | | currently remote connect(b/w gluster-blockd's) failed cases such as, ECONNREFUSED No-one listening on the remote address. ENETUNREACH Network is unreachable. ETIMEDOUT Timeout while attempting connection ... are considered as CONFIGFAIL, this patch defend on these errno's. Signed-off-by: Prasanna Kumar Kalever <prasanna.kalever@redhat.com>
* gluster-blockd: treat delete success if block doesn't existPrasanna Kumar Kalever2017-02-201-0/+15
| | | | | | | | | | | | | problem: say because of some reasons create failed to config on node, so it will log CONFIGFAIL in the metafile. At the time of delete since config failed it is obvious that block will not exist. since delete cannot find it now it fails to delete hence returning -1. solution: treat delete success if there is no block with given name on that node.

* meta: thread safe GB_METAUPDATE_OR_GOTOPrasanna Kumar Kalever2017-02-162-64/+80
| | | | | | | | | | | | GB_METAUPDATE_OR_GOTO used an already opened glfs fd to update the meta data, since we have mpath number of threads writing to the same metadata file simultaneously, this will lead to thread concurrency and data consistency issues. Hence this patch protects GB_METAUPDATE_OR_GOTO with a lock and removes fd sharing by moving glfs_creat/open and glfs_close within the MACRO.

| | | | | | | | | | | | | | | 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.
