Hi Again,

My second question is about RAID sync.

Just for my curiosity, I am testing RAID1 on two empty 110 gig partitions, 
the system takes about 3h30 to resync, why is it taking so long ?

Here is my idea: As the RAID layer has nothing to do with the FS layer,
the raid driver (I use md) does not and can't see the difference between 
a used block of data and an unused block of data. That's why it has to 
resync everything. Am I right ?
 
Thanks guys,
