Set up RAID on Dell Poweredge 2850

Today I had a hard day. Our server HDD crashed (I think it had a bad sector or something? Friend of mine checked our server and said it's hard disk broken) and we had to change HDD. We got 4 SCSI HDD (72gb) for a cheap price. And decided to make a RAID. But it is way harder than regular PC RAID. I've followed THIS tutorial and settled up very good raid configuration. But real problem was just started. After setting up raid and installing nice clean centos 5.5 I decided to put a old HDD into server and copy files from there to new HDD. But server won't recognize my old HDD cause of RAID configuration. So I had to add old HDD as a RAID. And BOOM all Data is gone. It was very stupid step :( . I didn't find a way to add (mount or something) a HDD to RAID configured server. If you have solution for this pls share with me. Also I wanna restore my old HDD data. Is there a way? And again never ever try to add HDD to a RAID as a RAID

HackUB (Hackathon Ulaanbaatar) - Organizing event

Everything starts with something, and there is always first time. So this August with bunch of friends we decided to organize an event. And possibly biggest event for Mongolian IT crowd. We never actually organized any event though. All had none to small experience about organizing anything. But anyhow we started planning it. So as usual this is reminder for me. Even event is fully planned, all the speakers even the most responsible one could cancel out last minute. So always follow up speakers and prepare plan B C for them, as replacements. And if that happens just casually change speaker and be truthful to audience. They won't panic as much as you do. Be prepared for stuff. For this event everything came to in place on last minute. Printing, venue, even funding got accepted on last minute. So try to reduce those LAST MINUTE things. Those things will break your schedule and leave a huge impact. At least try to print materials that won't change as soon as possible.  Get ...
