[Pacemaker] Failure of the resource migration from GUI

Hi Yan,

I referred to your patch. 
I gave the following patch.

----------------------- patch ------------------------------------------------------------
+       mgmt_log(LOG_INFO, "yamauchi ----- migrate_cmd0:%s",argv[3]);
        if (STRNCMP_CONST(argv[3], "True") == 0){
                strncat(cmd, " -f", sizeof(cmd)-strlen(cmd)-1);
                mgmt_log(LOG_INFO, "yamauchi ----- migrate_cmd1:%s",argv[3]);
        }
+       mgmt_log(LOG_INFO, "yamauchi ----- migrate_cmd2:%s",cmd);

        if (STRNCMP_CONST(argv[4], "") != 0){
                if (regex_match(duration_regex, argv[4])) {
                        strncat(cmd, " -u \"", sizeof(cmd)-strlen(cmd)-1);
                        strncat(cmd, argv[4], sizeof(cmd)-strlen(cmd)-1);
                        strncat(cmd, "\"", sizeof(cmd)-strlen(cmd)-1);
                }
                else {
                        mgmt_log(LOG_ERR, "invalid duration specified: \"%s\"", argv[1]);
                        return strdup(MSG_FAIL"\nInvalid duration.\nPlease refer to "
                                        "http://en.wikipedia.org/wiki/ISO_8601#Duration for examples
of valid durations");
                }
        }

        strncat(cmd, " 2>&1", sizeof(cmd)-strlen(cmd)-1);
+       mgmt_log(LOG_INFO, "yamauchi ----- migrate_cmd3:%s",cmd);
------------------------------------------------------------------------------------

And the log when I chose True and False by operation to migrate was the following thing.

[root at ais-1 ~]# tail -f /var/log/messages | grep yamauchi
Nov  4 09:39:33 ais-1 mgmtd: [12837]: info: yamauchi ----- migrate_cmd0:\True
Nov  4 09:39:33 ais-1 mgmtd: [12837]: info: yamauchi ----- migrate_cmd2:crm_resource -M -r group -H
ais-2
Nov  4 09:39:33 ais-1 mgmtd: [12837]: info: yamauchi ----- migrate_cmd3:crm_resource -M -r group -H
ais-2 2>&1
Nov  4 09:39:53 ais-1 mgmtd: [12837]: info: yamauchi ----- migrate_cmd0:\False
Nov  4 09:39:53 ais-1 mgmtd: [12837]: info: yamauchi ----- migrate_cmd2:crm_resource -M -r group -H
ais-1
Nov  4 09:39:53 ais-1 mgmtd: [12837]: info: yamauchi ----- migrate_cmd3:crm_resource -M -r group -H
ais-1 2>&1

After all backslash seems to be in the top.

Possibly will not there be a problem at the time of the transfer of the parameter with the daemon?

Best Regards,
Hideo Yamauchi.
