What is the maximum size of a single LV?
The answer to this question depends upon the CPU architecture of your computer and the kernel you are a running: • For 2.4 based kernels, the maximum LV size is 2TB. For some older kernels, however, the limit was 1TB due to signedness problems in the block layer. Red Hat Enterprise Linux 3 Update 5 has fixes to allow the full 2TB LVs. Consult your distribution for more information in this regard. • For 32-bit CPUs on 2.6 kernels, the maximum LV size is 16TB. • For 64-bit CPUs on 2.6 kernels, the maximum LV size is 8EB.
