Hi Eugen, > If you want to boot from RAID / which is not ext2 or ext3 > an ext3 /boot (which can be RAID, too) is most useful. Apart from using a software RAID card connected to HDs, I never use Linux/FC/RH software RAID before. I'm interested to have a test. Please help me to understand 1) Do I need 2 HDs for RAID 0/1/2? 2) If 1) above be "YES", whether both of them have to be connected as master on primary IDE and Secondary IDE respectively. 3) Is there a visible improvement on operation in running RAID 0/1/2 Please advise. TIA B.R. SL
