Subject: 2.6.29 - raid10 issue - spares do not get synched automatically

Hello,

I am using 2.6.29 on a debian lenny. Anyway, I am having problems with a 
raid10 sandbox setup consisting of 4 loopback devices. To make a long 
story short:

I created a raid10 array with all these 4 devices (loop0-loop3)
then I set two devices faulty, removed them .. checked if I can still 
write to the array (which I could, so I/O errors, nothing in dmesg):

BUT - here it comes: once I am trying to (re)add them (I zero'ed the 
superblock before) they're only getting added as spares and the array 
will not sync.

Here's the logfile with mdadm -D /dev/md0 in between so one can see what 
is going on:

Any ideas?
