virsh pool-build pool [options]

virsh pool-build initializes a previously-defined libvirt storage pool. The exact action depends on the pool type: for directory-based pools it creates the directory; for disk, LVM, or logical pools it formats the underlying device; for NFS pools it may set up the mount point. After building, the pool can be started with virsh pool-start.For some pool types (e.g. dir with an existing directory) the build step is a no-op or unnecessary, but is harmless. The --overwrite option allows reinitialization that destroys existing data on the target, so use it with care.

--overwrite

Overwrite existing data.

Fail if data exists.

The --overwrite flag will erase existing data on the target storage. The pool must already be defined (via virsh pool-define or pool-define-as) before building. Not all pool types require or support building.
