Creating a large (8TB) file system

Question & Answer


Question

How do I create a large file system (8 TB)?

Answer

There are four steps to this process: create a physical volume, create a volume group, create a logical volume and put the file system on the logical volume. In practice, you could run the following commands:

----------------------------------------------------------
pvcreate /dev/sde
vgcreate MyLargeGroup /dev/sde
lvcreate -L 8T -n largevol MyLargeGroup
mkfs.ext3 /dev/MyLargeGroup/largevol

----------------------------------------------------------

where /dev/sde is the SAN, MyLargeGroup is the volume group and largevol is the logical volume.  This example would create an 8 TB ext3 file system on /dev/sde.
