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 ?
