* glusterd,cli: Enable errstr for peer detachKaushal M2012-05-181-0/+1
| | | | | | | | | | | | | This patch adds an op_errstr member to the gf1_cli_deprobe_rsp structure to enable return of an errstr to cli.

* glusterd, cli: Enable errstr for peer probeKaushal M2012-05-181-0/+1
| | | | | | | | | | | | | | | | | | | Presently glusterd only returns an errno to cli for peer probe command. This patch allows glusterd to return an errstr as well to cli. An op_errstr member has been added to gf1_cli_probe_rsp and gd1_mgmt_probe_rsp structs to allow this. In case of an error, cli will display the errstr if it was set. If errstr is not set cli will display the error message based on errno. Also, to allow for return of errstr in cases such as handshake failure, an errstr member has been added to the glusterd_peerctx_t struct.

* cli,glusterd: more volume status improvementsKaushal M2012-03-291-12/+13
| | | | | | | | | | | | | | | | | | | | | | The major changes are, * "volume status" now supports getting details of the self-heal daemon processes for replica volumes. A new cli options "shd", similar to "nfs", has been introduced for this. "detail", "fd" and "clients" status ops are not supported for self-heal daemons. * The default/normal ouput of "volume status" has been enhanced to contain information about nfs-server and self-heal daemon processes as well. Some tweaks have been done to the cli output to show appropriate output. Also, changes have been done to rebalance/remove-brick status, so that hostnames are displayed instead of uuids.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Mountbroker is configured in glusterd volfile through a DSL which is restriced enough to be able to appear in the role of the value of a volfile knob. Basically the DSL describes set-theorical requirements against the option set which is sent by the cli (in the hope of getting a mount with these options). If the requirements meet and the volume id and the uid who is to "own" the mount can be unambigously deduced from the given request, glusterd does the mount with the given parameters. The use case of geo-replication is sugared by means of volume options which then generate a complete mount-broker option set. Demo: - add the following option to your glusterd volfile: option mountbroker-root /tmp/mbr option mountbroker.fool EQL(volfile-id=pop*|user-map-root=*|volfile-server=localhost)&MEET(user-map-root=john|user-map-root=jane) - before starting glusterd, create /tmp/mbr owned by root with mode 0755 - with cli, do $ gluster system:: mount fool volfile-id=pop33 user-map-root=jane volfile-server=localhost - on succesful completion (volume pop33 exists and is started, jane is a valid username), the mount path will be echoed to you - you can get rid of the mount by $ gluster system:: umount <mount-path> Change-Id: I629cf64add0a45500d05becc3316f67cdb5b42ff BUG: 3482 Reviewed-on: http://review.gluster.com/128 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Vijay Bellur <vijay@gluster.com>
