A few questions about FC6


Yooo,

My first question is about Fedora's volume management. It appears that FC automatically formats the entire freespace you have on your disk within it's LVM. My question is, is it such a bad thing if you delete the LVM and create your own partitions?

Second question has to do with the virtualization software that comes on the disc. When you're installing it and you can choose the software that gets installed, there is virtualization software (I'm assuming this is what you use if you want to run, say, Windows and Linux at the same time. Please correct me if I'm wrong.) and it installs OK. When it comes to loading, everything is fine in the scroll screen except when it gets to something called 'Xend'. IT takes about 2 minutes to load and after it does is when the login screen is supposed to come up, except it doesn't. Why is that?

Last question, I'm having problems installing software through Yum. I'm accustomed to using Suse 10.0 and YaST. Yum is quite different. I go to software management, I think it is anyway, and when I open it, it attempts to connect to the internet for a mirror site. It doesn't attempt to do anything from disc. Any help is much appreciated.

Thanks,

Brandon

1.) It is recommended to partition the disk using LVM.Put linux in the first Volume Group and create a second Volume Group for Guests VMs.

2.) "after it does is when the login screen is supposed to come up, except it doesn't. Why is that?"
What are you trying to say here.

As far as LVM is concerned a user can opt it out by offering one partition to mount "/".

Never met any complaint from RH9, FC2, FC3, FC4, FC5 and Fc6. They still boot.

Anant,

I've installed FC6 a couple of times, and on one time when I installed the virtualization software offered on the disc, it loads something called 'Xend'. It takes about two minutes for this 'Xend' item to load. After it loads, its supposed to go to the login screen, but the loginscreen does not show up at all. It just goes to a black screen.

Saikee, why is it recommended to use LVM? What benefits does it offer?

Thanks,

Brandon

I think in the old days it is quite useful to pool small partitions and hard disks together to form a LVM, especially for servers work. For desktop by individuals this can be an added complication. A normal partition is easier to handle and can be recognised by other systems too.

I could be wrong but with 400 to 500Gb hard disks and RAID commonly available the role of LVM may not be as attractive as before but no doubt many Red Hat/Fedora users will have better view on it.

One thing for sure if you install another system inside a LVM no boot loader can read it and so the associated boot loader has to be accommodated in a /boot partition if it does not already exist.

I think LVM is useful in a handful of situations, but overall I believe RAID will eventually overtake LVM. With RAID JBOD, LVM seems nearly obsolete. As you mentioned, it was probably useful as a "poor man's" JBOD RAID setup back in the day, but now with most of the newer decent motherboards coming with onboard RAID controllers, I see LVM using it's usefulness in the future.

FYI:
Before I knew what RAID and LVM were, I heard about LVM first. I have a 750GB LVM setup with 3 250GB drives. Knowing what I know now, I'd use RAID and will probably migrate in the near future. It's a recording setup for MythTV and I get HDTV files that are around 7.5GB a piece, so it fills up fast.

Oh yeah, so in response to the original poster, no, I wouldn't necessarily use LVM on my desktop system(s).

Cool

Thanks for the info. From what I can gather LVM is a lesser alternative to RAID (I'm familiar with RAID).

Thanks,

Brandon
