RAID vs Multiple Drives
RAID is a method of spreading your data across disks.It can vary from simply treating all of your disks as one large disk (and providing no redundancy for your data) to what's known as striping where your data is written to multiple disks in a way that means if one of the disks fails, the system can still reconstruct your data from the remaining disks.If you simply put / on one disk, tmp on another and dev on the third, this isn't RAID and doesn't provide any kind of redundancy for your data - e.g. lose disk 2 and you've lost tmp.I think with three disks, the best option for using RAID is what's known as RAID 5 - this will make your three physical disks look like a single 'logical' disk.All your filesystems will be put on the logical disk but the failure of a single physical disk will not result in loss of data.Put RAID 5 into Google and you should be able to find out plenty more information - it's been a while since I had to deal with RAID so my descriptions are a little vague.Someone else on this list will likely give a better description.Cheers,Ade.> Date: Wed, 25 Jul 2007 13:11:22 -0600> To: debian-user@lists.debian.org> Subject: RAID vs Multiple Drives> From: [EMAIL PROTECTED]> > Tell me to move this if this is the wrong place to ask, but:> > RAID recognizes a number of HDD's as one homogeneous drive.> > If I have, say, 3 HDD's, and I divide those 3 between my /, /tmp, and /dev locations (I picked arbitrary points), is that like having a virtual RAID system?

RE: OT: Cycling: [was: [OT] A significant negative impact on Linux's popularity?]
Hi All,Here in the UK, cyclists are treated the same as cars, trucks etc on the road and are subject to the same laws.This means they have to ride with the flow of traffic, stop at red lights, give way to pedestrians etc.Mind you, the roads are so dangerous for cyclists most just use the paths (illegal but not enforced :o)Cheers,Ade.> Date: Tue, 17 Jul 2007 10:15:23 -0500> From: [EMAIL PROTECTED]> To: debian-user@lists.debian.org> Subject: Re: OT: Cycling: [was: [OT] A significant negative impact on Linux's popularity?]> > Kent West wrote: > > I can't say I ever recall it being law, but I remember my grandparents > > teaching me to walk against the flow of traffic, so that you can see > > the driver and the driver can see you, and I grew up with the concept > > of doing the same on a bike (I'm unsure if they taught me that, or if > > I just made the cross-over in my own child's mind); this was back in > > the 60's.> > btw, this was in rural (at the time) Texas (Hood County, Granbury, > Acton, Lipan area)> > -- > Kent> > > -- > To UNSUBSCRIBE, email to [EMAIL PROTECTED] > with a subject of "unsubscribe".
