Hey, I'm pretty new to this so I'm just curious as to the best way of doing this.

I have 2 seagate 120gb IDE running in a fedora C3 box as a fileserver. I'd like to mirror the hdds, but how should I do that. I have a cheap SYBA PCI card with RAID 0,1,0+1. Or should I go with software like here and forget the SYBA card? http://www.tldp.org/HOWTO/Software-RAID-HOWTO.html

Also, I put the hds into a raid1 set, but when i tried to install fedora onto it, I got an exception error when it began to install the OS. Should I ditch that and just go with the software?

thanks in advance,

Doesn't linux only run with software raid? I'm pretty sure linux doesn't support the hardware alternatives.
 
There is an ATA raid subsystem for Linux that can be used for controllers that are not full blown hardware accelerated RAID units. I am unable to comment on performance of this implementation as I've never used it (there was a thread that had some info on it awhile back), but it sounds like the security of the data is more important than throughput. Stay away from RAID-5 of any sort on a C3 system - the parity calcs will eat your CPU alive. I'd stick with software RAID-1 mirroring here.
 
how's that possible? don't webhosts use raid in their systems along with linux?

edit: you posted right before me :)
