Well there is the names that people like to use (/dev/md/jeffadm) and names that the kernel likes to use (md1, md2, md127). When you use --examine, it tries to use the name that people might like. When you use --detail --scan it primarily has access to the names the kernel likes, so it used those. > > 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 Yes, that it weird. I don't know how they came to be out of sync. mdadm --incremental --rebuild-map will fix it..
