> Hi,
> I am just about to reinstall my home server with Centos5 and not sure the best configuration for the disks.  I have a 3Ware 9550SX Hardware RAID card with four 200GB drives in hot swap bays.  Currently I have two 200GB mirrored RAID sets, one for O/S and the other for data.  I am thinking about recreating the RAID set as one big RAID5 so that I can maximize the data area as only 10% is used in the O/S area.
> How does this approach sound ?  The server is a dual Opteron 250 with 6GB RAM.  Any help appreciated.
> Regards,
If you want to keep the raid 1 and maximize the data set, you can always use 
LVM over the raid arrays. That way you can use the space however you want to.
