Hello,

I have just upgraded mdadm from v1.8.0 to v1.8.1 and now, each time when I 
create new array, it contains the same UUID:
6b8b4567:327b23c6:643c9869:66334873.

root@fw1:~# mdadm --stop /dev/md6;echo y|mdadm --create /dev/md6 --level=1 --raid-disks=2 /dev/sd[ab]7;mdadm -D /dev/md6|grep UUID
mdadm: /dev/sda7 appears to be part of a raid array:
     level=1 devices=2 ctime=Mon Jan 10 09:45:29 2005
mdadm: /dev/sdb7 appears to be part of a raid array:
     level=1 devices=2 ctime=Mon Jan 10 09:45:29 2005
Continue creating array? VERS = 9001
mdadm: array /dev/md6 started.
            UUID : 6b8b4567:327b23c6:643c9869:66334873

root@fw1:~# mdadm --stop /dev/md6;echo y|mdadm --create /dev/md6 --level=1 --raid-disks=2 /dev/sd[ab]7;mdadm -D /dev/md6|grep UUID
mdadm: /dev/sda7 appears to be part of a raid array:
     level=1 devices=2 ctime=Mon Jan 10 09:45:33 2005
mdadm: /dev/sdb7 appears to be part of a raid array:
     level=1 devices=2 ctime=Mon Jan 10 09:45:33 2005
Continue creating array? VERS = 9001
mdadm: array /dev/md6 started.
            UUID : 6b8b4567:327b23c6:643c9869:66334873


Od version (v1.8.0) works just fine.

This is a "development" release of mdadm. It should *not* be
considered stable and should be used primarily for testing.
The current "stable" version is 1.8.0.

So why did you change it? :)
