Re: Why do I get different results for 'mdadm --detail' & 'mdadm --examine' for the same array?

Ok.  I got beaten up for top posting once, and was told to 'keep things
in order'.  Next time, though -- question first, in BOTH the title and
the body.

No, not just the names. I guess I don't know the PURPOSE of the names,
if the names we give things aren't necessarily the ones that get used.

But more a problem are the different UUID's:.

cat /dev/.mdadm/map
---------------------------------------------------------------
md126 0.90 19f2b21c:e54f9e1a:be5ad16e:9754ab5e /dev/md/0_0
md127 1.2 79fb7ad4:289bfae5:86c535ff:202960f2 /dev/md127
---------------------------------------------------------------

mdadm --detail --scan
        ARRAY /dev/md127 metadata=1.2 name=jeffadm:jeffadm1
        UUID=d84afb64:e6fa2b64:ff21c975:f9765431
        ARRAY /dev/md/0_0 metadata=0.90
        UUID=19f2b21c:e54f9e1a:be5ad16e:9754ab5e


Notice that the UUIDs for /dev/md/0_0 match, but for /dev/md127 the
don't.
