Help setting up DHCP and RAID in Ubuntu

Hi everyone, Is there anyone in the Hamilton area who could spare some time (in person) to help a linux newbie? I've been dabbling with a new computer, and I've done everything I needed to do with the exception of RAID-1 and DHCP. I have a feeling I've also stuffed up something, as I've got an external eSATA hard drive (for backups) which doesn't auto-mount, and I can't figure it out. I'm sorry to say I'm a bit tight on the old wallet this week, but anyone who lends a hand will get a nice cup of coffee, and their choice of a couple classic linux books I've got hanging around. I live in the Hillcrest area, but I'm quite happy to meet elsewhere if desired. More details available on request. :-) Thanks in advance! - Eric

A great source for Ubuntu help is their community wiki: Raid1 - https://help.ubuntu.com/community/Installation/RAID1 DHCP - https://help.ubuntu.com/community/DnsAndDhcpServer

If no one else offers to help you at your home, you can always bring your computer along to the Saturday workshop and we'll see what we can do. We'll even provide you with coffee :-) http://wlug.org.nz/SaturdayWorkshop.2007-06-09 -- simon

Hey :-) Send me an e-mail, I can't say we'll get it completely sorted, but I'll give it a shot :-) I can't say I know everything, but I recently managed to get 2x 80GB PATA HDD running RAID1 (looks like 160GB), then get that RAID1 array plus a 160GB SATA HDD into another 320GB RAID1 array - don't ask :-P I will bring this machine over so we can look at its config. Also my desktop is running Ubuntu 6.06 (Dapper?), and has an eSATA port - never used it, but might as well bring it along, to see if your external drive does work etc. You have spare power cables/network cables/multiboxes/mice/keyboards/etc?

A RAID1 is actually a mirror - so two 80GB harddisks in a RAID1 will present a single 80 GB volume. You've possibly used RAID0, which so named because it offers zero protection against disk faults. See http://www.wlug.org.nz/RAID for more information. Unfortunately for the OP, taking an existing install on a single disk and converting it to a software RAID1 set under linux is fairly tricky to do. There are howtos around, but it's time consuming and potentially dangerous, and it's definitely easy and probably quicker to reinstall the machine and set up RAID1 from within the installer (even the Debian Sarge installer supported this, btw).
