Hi, i want to reconfigure my server fairly dramaticly and im trying to work out how i can do it without great pain. I currently have 3 drive of ~ 20GB, i have another 20GB and 6.4GB i want to include in my array. I have about 40Gb of data currently on the drives, about 10GB on a raid0, the rest normal partitions. I want to get my 4 ~20GB drives into a raid5 setup, with 3 data disks using 18GB of each, and one parity disk, so i can have about 54GB of storage I will use about 2GB from each of the 5 drives for a raid0 And whats left over for the linux system Is it possible to integrate a disk with data already on it into a raid5 array? I was hoping there may be some trick with marking the disk as bad, spare or whatever to enable the data to live through the process. So of a total storage of about 86GB raid5 will use 72 GB, 18GB of my data can be on one of the raid5 disks(?), i can move upto 10Gb of data to anywhere that is not going to be a raid5, i can find a few GB of space via the network, and backup whats left on cds. I guess it would be easier to go and buy a tape backup, but im not a big fan of them, and dont know much about them either. Any ideas, comments advice ? Thanks Glenn McGrath
