RHEL 5 supports only 2 TB space for a partition !


Dear Friends ,

I am using Redhat Ent Linux 5.0 with a EMC storage which HDD space is 4 TB. After Installing RHEL 5 , I get 4 TB space available but when I am going to create a partition then the OS show 2TB available space . I cannot create a partition above 2TB space . Is there any limitation of linux regarding this issue ?

I am trying to create partition during installation of o/s and after installation of o/s (using fdisk) .

Plz inform ..

If I recall correctly you need gpt. I believe fdisk is broken in the large filesystem area. Try using parted instead.

Looks like RHEL does support large filesystem limits http://www.redhat.com/rhel/compare/. Maybe its the EMC?

Redhad supports >2TB but fdisk does not. To create a partition >2TB you need to use GPT labels. Its the utility thats the issue, try parted.

Code:
parted /dev/sdx
mklabel gpt
mkpart primary 0 4TB
Something like that should do the trick
