[root@vikas-sb build]# /usr/sbin/gluster volume rebalance gl2 fix-layout status Usage: volume rebalance <VOLNAME> [fix-layout|migrate-data] {start|stop|status} The old way of invoking still works: [root@vikas-sb build]# /usr/sbin/gluster volume rebalance gl2 status rebalance completed The culprit code is in cli/src/cli-cmd-volume.c: cli_cmd_volume_defrag_cbk: if (strcmp (words[3], "start") && strcmp (words[3], "stop") && strcmp (words[3], "status")) { cli_usage_out (word->pattern); parse_error = 1; goto out; } words[3] is supposed to be [fix-layout|migrate-data]. The code is still checking for "start", "stop", and "status", and exiting.
