Hi list,
when a user does `mdadm -C /dev/md0 -l <any> -n <whatever fits>
<devices>`, the array gets rebuilt for at least RAID1 and RAID5, even if
the disk contents are most likely not of importance (otherwise we would
not be creating a raid array right now). Could not this needless resync
be skipped - what do you think?
If you want his behavior you can always create the array with a
'missing' device to hold off the resync process. Otherwise, if all
disks are available, why not let the array make forward progress to a
protected state?
Also, the resync thread automatically yields to new data coming into
the array, so you can effectively sync an array by writing to all the
blocks.
