General concensus on the linux raid list is that striping swap is bad because the whole machine will die if one of the disks containing a swap partition fails. Hence the RAID1 for swap. Actually, I intend to try putting swap on RAID10 by creating 3 mirrored pairs and striping all three together. This could be considered to be overkill! I'm not too concerned about performance for /tmp and /var/tmp so I'll probably stick with them on RAID5, although now you've mentioned it I may consider RAID10 the same as the swap partition. >> Is it possible to configure software RAID at install time with Core >> 2 or will I need to create the arrays before I install? > > Not sure if the installer has improved in this respect since RHL 7.2, > but you could not set chunk size then.

Can this be done from a terminal window whilst the installer is running, i.e. do the raid tools come on the Fedora install disk(s)? Or do I need to boot from another distro CD, e.g. knoppix or Gentoo and create the partitions that way? Do you have any recommendations regarding chunk size? Thanks, R.
