We are trying to use a 13 Tb disk on one of the latest RedHat system;
namely, 2.6.18-128.4.1.el5xen.
"ext3" cannot see beyond 2 Tb.
ext3 can manage 16TiB filesystems, but some tools (like "fdisk") can
only deal with 2TiB.
You can use GPT partitions and "parted" instead of "fdisk" like Margaret
suggests.
If you want to use standard tools, just split your 13TiB storage into
2TiB pieces and "glue" them with LVM, this is how I use a +3TiB storage.
- If the storage is seen like a single disk by the system, create 2TiB
partitions with fdisk and change the type for "8E" (LVM), then add this
partitions to LVM with "pvcreate /dev/sdX1 /dev/sdX2 /dev/sdX3 ..."
- If you can, create 2TiB LUNs, and use them directly in LVM, this is
much simpler, you don't have any partition to make : "pvcreate /dev/sdX
/dev/sdY /dev/sdZ ..."
After that, create a LV with the LVM devices and then create a LV in the
VG and then you can do a "mkfs.ext3" on the 13TiB LVM device.
