Hi all experts!

What is use of lvm and raid in industries?

I want to know this.

Yes, it is used.

Look up the benfits of LVM over traditional partitions and the benefits of RAID are obvious (assuming you've actually looked it up at all). Smells like homework to me.

Then you should look it up. It's widely used, and has different reasons for BEING used, and there's alot of different types. You don't give details on what the context is, so it's hard to say more.

However, since you're an RHCT, and BE, this should have been well covered in your courses and classes. Probably can look it up in your class materials.

I KNOW HOW TO CREATE ,EXTEND, DECREASE LVM PARTITION BUT I WANT TO KNOW WHAT IS ACTUAL USE OF LVM IN INDUSTRIES?
I AM RHCE , I KNOW NO WONDER FOR YOU, BUT STOP WRITING THIS

"However, since you're an RHCT, and BE, this should have been well covered in your courses and classes."

INSTEAD OF WASTING TIME WRITING THIS LINE YOU COULD WRITTEN AT LEAST ONE LINE ON LVM, DON'T YOU THINK SO? OR YOU ENJOY EMBARRASSING OTHERS?

I think should stop writing here on LQ. No one, I mean NO one is going to spoon feed you. You got to look up and read materials and when you stumble upon something, you can ask. You will surely get help, but being rude DOES NOT HELP.
And STOP USING ALL CAPS WHILE WRITING. AND YOU SHOULD UNDERSTAND NOW WHEN YOU READ THIS HOW IRRITATING IT IS TO READ ALL CAPS.
ALL CAPS IN NET LINGO MEANS YELLING AND SHOUTING, SO STOP YELLING AT OTHERS AND go and read some wikis.

Well, if you're going to shout and be rude, you can sort yourself out. I'm out. Nobody owes you an answer and demanding one will make people ignore you. Like me.

Some people who know your posting history are going to be reluctant to anwser your threads at all. When you have little tantrums like this, you are only digging your hole deeper.

Stop and think about the question you asked: LVM and RAID are tools. Tools get used in many different ways depending on the situation. Your question is almost like saying: "Who uses power drills and for what?" The answer would be: "Many different people and whenever they need to drill a hole."

I wrote a couple lines on LVM's, did you read them? Specifically, this:
If you know about LVM's, have created/modified them, then it's very puzzling as to why you'd even ask this question. Sort of like saying "I am a professional race car driver...what is the purpose of anti lock brakes, and when are they used?".

No one is trying to embarrass you, but you are doing a fairly good job of it yourself. You don't want to read instructions, follow advice, or answer questions when folks ask them. You also have said that you've got a degree, and a certification, but don't seem to have the knowledge that goes along with them, so it's very puzzling, and makes folks reluctant to answer you.

How do you all people get time to write all these things?

Guess the same way you have time to post the same, simple questions over and over.

Seriously, you come here for help, but you don't seem to want to put any effort into doing anything, or learning anything. You want to be spoon-fed an answer, and then spout off rude comments, and have childish little fits, when someone asks you a question. No one objects to giving you help, but nothing ANYONE here has ever told you, seems to make a difference. You don't follow instructions, answer questions we ask you, or post useful information. Do you do the same thing on other forums?? How do they react to you there??

Have you read any of your other posts, and really thought about the content? Why don't you ask a friend of yours to read them, and have them give you their honest opinion....
