Hi,
Is it possible to create one raid volume of 3.3 TB (9550SX-8lp X
WD5000YS – 8nos) and create a file system with ext3? (CentOs4.3 64bit)
The maximum I am getting is 1.24tb and fdisk returns no more space
available. But when I say fdisk /dev/sda it list full size of 3.3 TB.
But I can not create partitions more than 1.24TB.
Any idea?
you should try creating an LVM instead of creating a partition ....
with LVM you dont need to create a partition ... you can use the whole
device ....
from lvm2 faq:
*4.1.13. * 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.
(Yes, that is a very large number.)
cheers,
Nick
