Larger than 2TB volumes
 

Hi,
Can anyone tell me which versions of Redhat support larger than 2TB luns?


Thanks in Advance!!

i remember having a discussion about this at work (i work for a linux centric hardware vendor) and i remember the solution to this problem is to use bsd disk labels when partitioning your volumes. I know for sure anything after Fedora Core 2 should work with this method.

It's the kerne that supports it, and you need to specifically compile in support for large volumes like that. I can't remember the name of the property but it's pretty obvious, just cd /usr/src/linux and make menuconfig. Turn it on (not as a module) and then make and cp the bzImage to your /boot partition :)

It's actually the filesystem that supports it, and that's in the kernel.
You might take a look here, as the list seems pretty accurate:

Thank you for your help. I work for Engenio, a storage systems company. I am not very familar with Linux at all and I had a customer asking me about the 2TB support. Thanks again for your help!
