Hi again, Here is my last question about RAID for now. I saw a lot of docs about RAID installation, but I was not able to find one which clearly explain what to do after a HD crash. Does someone has a good link for me ? For example, let's say I have two new IDE HD in a RAID1 array, raid-disk1 and raid-disk2. If raid-disk1 crash, I have to (from linux-raid-How-to) Power down the system replace the failed disk powerup the system user raidhotadd to insert the new disk in the array as raid-disk1 But what should I do to make sure that raid-disk1 will reconstruct from raid-disk2 ? If raid-disk2 reconstruct from raid-disk1, I will lose all my data right ?
