Did you *specificly* install CentOS 5.2 (as opposed to 5.1 or 4.7? Do you want the URLs of of the CentOS 5.2 & RHEL 5.2 bug reports? Did you install onto bare partitions and then migrate to RAID and/or LVM later? Note this is *software RAID*, not hardware RAID. > > Now, let's see if we understand the situation clearly: > > 1.

I want the option of falling back to the existing (working) Ubuntu system, in case there are problems with the CentOS setup. Right now, this is for a small (and relatively impoverished) small town library. The original setup (done by someone else who does not have the time, etc. to deal with it) uses LTSP and diskless thin clients. While this works, there are some performance issues. Because the LTSP uses the 'PC's as pretty much bare X Terminals, this means all of the real 'work' is done on the server itself. With several people working, often kids and teens playing Flash games and maybe one or two people using Open Office, the server litterally runs out of RAM and starts swapping, which slows everything down. I want to set up a slighter thicker clients using NFS mounted file systems in hopes that this will work better. There is a backup process in place, but it has not been working lately, since there seems to be a problem with sshd on the external server. Even if it was working it might be problematical to restore it anyway because of the rather funcky internet connection we have (HughesNet satelite dishes -- nothing better is available here in the wilds of Western Mass). The main reason for moving from Ubuntu to CentOS is that I am much more familar / confortable with RedHat flavored systems. Ubuntu seems to have more 'magical' things going on, which I could not figure out. I think Ubuntu tries to be overly 'helpful', which might be nice for some users and probably makes more sense for home desktop users, but was just frustating for someone trying to do some 'outside of the box' things. > > Now how much time have you spent on this "project" so far??
