Thread title should read: is LVM available for Linux/CentOS

We are looking to install Linux/CentOS on a server.

With another server that we have there are space/storage issues because, it would appear, that whomeever loaded Linux took the defaults for partitions. To complicate things, developers were loading their content on the root (/); other partitions were configured larger than necessary with low % used.

As we get ready to load Linux, my question is I would like a better way to allocate & manage storage....

Is LVM available on every distribution of Linux?

Will LVM be available to me with CentOS???



thanks.

It's part of the default install on Centos.
The RHEL/Centos Linux details are here

Linux LVM generally (you prob don't need this)

I appeciate the feedback!!

I am pretty new to Linux in particular from an Admin perspective. I am not uncomfortable at all, mostly that I have not had any considerable time working in Linux.

My next question is on a scale from 1-10 with 10 being the most difficult how would you rate this?

The reason I am asking is that it has come to my attention that the person that was planning to install has indicated he's not the person to implement LVM2.

I am a PM/BA with a development background in other environments.

We have a server at my location that I am waiting for them to install Linux on. For my main project the server is at another location. So I'm wondering if I could install Linux and implement LVM2 on the local server, get an understanding and one implementation under me and then travel offsite to the other server.

Any suggestions/recommendations?

Well, the easiest thing is to grab a spare pc (or dual boot, but that's fiddly) and install it. As I said above, the default install will utilise LVM2, so you don't have to think much.
During the install (use the graphical option) it will show you how it's going to layout the LVM(s) and you can alter them then. Easier than after install.
Highly recommend reading that first link of mine, it's the Deployment/HOWTO guide for RHEL 5 (= Centos) and it's pretty clear.

Again, thanks for you suggestions and advice.

I just wanted to share my progress and some info........

I have since downloaded CentOS 5.3 and now have discovered that I have Red Hat Enterprise Linux 5 available for one server.

Yes, I do plan to test the install and LVM configuration on a server that is local to me, which is a Dell R905 with two dual-core AMD Opteron 8000 Series processors, and I've been told it has 7t of storage. This is the Red Hat install. I just received some documentation for this server on Friday.

The others servers are Cisco MCS 7835's H2 and 7845's H2. For certain I will be loading one of each and may load all 4....just a time factor because I need to travel to them. CentOS installs.

One thing I have come to realize is that Red Hat is a distribution of Linux. Part of the confusion on my part is that I was told that the servers were all CentOS. So when I browsed this one particular server and saw Red Hat I just assumed it was a "special app".

While there is a lot going on this has been a really fun project for me.

I have been reading those links and moving forward!


Thanks.
