Creating Volume Objects With xlv

Creating Volume Objects With xlv_make

The xlv_make command creates volumes, subvolumes, plexes, and volume elements from unused disk partitions. It writes the logical volume labels in the disk volume headers only; data on the disk partitions is untouched.

After you create a volume, you must make a filesystem on it if necessary and mount the filesystem so that you can use the logical volume.

Caution: When you create a logical volume and make a filesystem, all data already on the disk partitions is destroyed. xlv_make can be run interactively or it can take commands from an input file. The remainder of this section gives two examples of using xlv_make; the first one is interactive and the second is noninteractive.

Example 1: A Simple Logical Volume
Example 2: A Striped, Plexed Logical Volume
Example 3: A Plexed Logical Volume for an XFS Filesystem With an External Log
