nothing has changed, except kernel minor version

exactly, in my case mdadm --examine output is somewhat weird as it shows:
/dev/sde1
this 0 8 33 0 active sync /dev/sdd1
/dev/sdd1
this 0 8 33 0 active sync /dev/sdc1
/dev/sdc1
this 0 8 33 0 active sync /dev/sde1
and /dev/sdf1 as sdf1
I think I can believe mdadm?
and that /proc/mdstat content comes directly from mdadm (that is with "exact"
sdc,d,e)?
what trouble me is that after I removed 2 disk drive from the bay, mdadm start
to recover:
md0 : active raid10 sdb1[1] sdc1[4] sdd1[3]
976767872 blocks 64K chunks 2 near-copies [4/2] [_U_U]
[=>...................] recovery = 5.0% (24436736/488383936)
finish=56.2min speed=137513K/sec
I guess that it is ok, and that it is recovering with the spare. But I would
like to be sure...
