tests/cluster.rc: support for virtual multi-server glusterd tests
Since http://review.gluster.org/4556 glusterd is capable of running many instances of itself on a single system. This patch exploits that feature and enhances the regression test framework to expose handy primitives so that test cases may be written to test glusterd in a cluster. Usage: 1. Include "$(dirname)/../cluster.rc" to get access to the extensions 2. Call launch_cluster $N where $N is the count of virtual servers Calling launch_cluster, starts $N glusterds which bind to $N different IPs and dynamically defines these primitives: - Variables $H1 .. $Hn assigned to hostnames of each "server". - Variables $CLI_1 .. $CLI_n assigned as commands to run CLI commands on the corresponding N'th server. - Variables $B1 .. $Bn assigned to the backend directories on each "server". - Function kill_glusterd, which accepts a parameter - index number of glusterd to be killed. - Variables $glusterd_1 .. $glusterd_n assigned to the command lines to restart the corresponding glusterd, if it was previously killed. The current set of primitives and functions were implemented with the goal of satisfying ./tests/bugs/bug-913555.t. The API will be made richer as we add more cluster test cases Change-Id: Ieb13ed9f4a72ac0321db0ca0844c7b294145bb32 BUG: 913555 Signed-off-by: Anand Avati <avati@redhat.com> Reviewed-on: http://review.gluster.org/4566 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Krishnan Parthasarathi <kparthas@redhat.com> Reviewed-by: Jeff Darcy <jdarcy@redhat.com>
