Fixes #1636 New format now generates a UUID and includes it along with the order of disks. So that UUID is the real order of disks and on command line user is able to specify disks in any order. This pre-dominantly solves our dilemma. ``` { "format" : "xl", "xl" : { "version" : "1", "disk": "00e4cf06-5bf5-4bb5-b885-4b2fff4a7959", "jbod" : [ "00e4cf06-5bf5-4bb5-b885-4b2fff4a7959", .... "c47d2608-5067-4ed7-b1e4-fb81bdbb549f", "a543293e-99f1-4310-b540-1e450878e844", "18f97cbe-529a-456a-b6d4-0feacf64534d" ] }, "version" : "1" } ```
