Still Need Help on mdadm and udev

[andyliebman@editshare.com]

Okay,

PLEASE somebody who knows answer the following:

1)  what is the difference between running

             mdadm -A -ayes 1/dev/md1--uuid=xxxxx /dev/sd*

    and

             mdadm -A -amd 1/dev/md1 --uuid=xxxxx /dev/sd*


    In other words, how do the "yes" and "md" options behave differently.


2)  If you create an array /dev/md0 with mdadm, is there any reason why
you shouldn't start it as /dev/md1?

The second option above (-amd 1) would NOT start an array that was created
as /dev/md0 (under an older mdadm -- 1.8.? ) whereas the first option
(-ayes /dev/md1) had no difficulty.

Thank you.
