GPT Partion issues
Wise men i got another one for you.
GPT partition. Been trying to install linux on a raid 5 (four 1TB drives) but linux is not happy with this setup. I get all sorts of issues concerning the drive setup. Fedora and Ubuntu cant see the raid at all. Centos see it but complains about a GPT partion and cant install, blablabla.
Google showed me several ways i can remove the GPT partion but dont think it works.
I need help. It needs to be raid 5 because of the environment.
Any ideas anyone?

Added to the above, I'd recommend using Linux software RAID over any motherboard "hardware" RAID.

Ok heres what i have done. I got Five drives in my system, No hardware raid or anything like that. One of them i used for the os. Once the OS was up, it deteched the other four drives. I then set software raid up on those other four. Looks like its working great. So what happens if the HDD on whicch i have my OS dies? Replace and re-install. What happenes to data on my raid? I will have to setup raid again on the new OS which means i will lose my data right?

KeremE... Originally I setup hardware raid giving me a total of aba 2.xxTB thats when i started getting the GPT issues with Centos. Yes it does see one big 2.xxTB but i get errors. I guess thats when the MBR issue comes in.
When your OS disk dies and you setup it again and then you'd create a Software RAID Volume, and add your disks again and nothing has been lost.
BTW what errors you get when you have 2 TB H/W assisted RAID ? In no way you can use MBR for partitions over 2 TB so you'll need to go for GPT partitions.

for hardware raid over 2TB, Linux report something similar to "Linux has detected a GPT partition blabla bla. Is this a GPT partition? I get a yes or no option. On either clicks, it say error then shows the GPT error message again. I think for now i will resolve to software raid and hope its as effective as Hardware raid.
Another issue and getting in relation to this GPT issue, I have set up hardware raid on a machine. Total space is about 1TB. Linux(Centos or Ubuntu) install fine but turns to freeze from time to time when in use.
This is a server installation we are talking about. Hardware is server based as well. When i do the installation withour HD raid, all is great. This obviously tells me something to do with the raid hardware but why? Why does it work sometimes and freezes sometimes?

This question has been classified as abandoned and is being closed as part of the Cleanup Program. See my comment at the end of the question for more details.
What is your configuration? Are you trying to install a hardware or software RAID? I guess your disks are not just regular SATA drives CentOS would be a better alternative as you've observed.
