Check the LVM-HOWTO at www.tldp.org.

Ooh. I learnt something today.

Note to self. Next time I install Linux, use LVM.

I've been using LVMs for a while - I have a pair of 2TB LVMs going here. If you lose 1 drive, it's ALL gone, fsck takes HOURS, yada yada. Don't just say 'what a great idea' till you think it thru.

If you set up your 2 TB systems to fail because of a failure on 1 drive then that is a misconfiguration on your part, not a problem with LVM. On Wed, 2004-09-15 at 10:10, Michael W Cocke wrote:

Not an opinion, fact. Now if you config'ed it that way on purpose, say you needed max performance and usable size then fine. But you made it seem like a single disk failure would take down LVM in general and that is just not the case if config'ed for high availability. On Wed, 2004-09-15 at 10:59, Michael W Cocke wrote:

Well, just as soon as the default configuration is for something besides what it is, I'll agree with you. In the meantime, however, I'll keep saying that you need to be careful.

And incidentally, unless you own a sheet metal shop or have a few thousand to waste, there simply isn't a good way to get more than about 2TB into a chassis, so how exactly were you figuring on setting up a RAID?

Network block devices? :) --Danny, pretty sure that'd kill your reliability...

2 TB in a single chassis, its not that hard

24 drives x 250 GB/drive = 6 TB

Did you read the original message? Not hard at all - for a few thousand, just like your ad price. Mike- -- If you can keep your head while those around you are losing theirs...

Thanks

Actually, one good way, is iSCSI, which uses IP to connect storage. Your drives could be anywhere that's reachable with IP.

I am preparing for my exams on Friday, I have successfully configured and unconfigured logical volumes,

If you post this three or four more times, you will be more likely to get response.

Now I need to prepare for my exams. google

Normally I don't care, but this time I will point out the "my mail is having problems, sorry if you get this multiple times" from the other post, and I'll also point out that the date in the header on the original message was yesterday.

Now that we all know it was an accident, feel free to resume making fun of Chadley. :)

--Danny Thanks Danny It doesn't bother me at all, I just needed to know more or less what it was intended for, I have got my answer that is not in human readable format and I am happy.

Thanks to all cheers -- -- Chadley Wilson Production Line Supervisor Pinnacle Micro Manufacturers of Proline Computers ==================================== Exercise freedom, Use LINUX =====================================
