Overview
Create, but do not start, a storage pool.
virsh pool-define-as <name> <type> --source-dev <source-dev> --target <target>
where:
name
The name of the storage pool.
type
Can be one of: "dir", "disk", "fs", "logical", "iscsi", "scsi", "mpath", "zfs", "sheepdog", "gluster", "netfs", "ceph", "rbd".
When using "pool-create-as" for a pool of type "disk", the existing partitions found on the --source-dev path will be used to populate the disk pool.
--print-xml
If specified, the command will print the XML of the pool object without defining the pool.
--source-dev
--source-path
Specifies the source directory path for directory-backed pools.
--target
The path for mapping of the storage pool into the host file system. For directory-backed pools, it is the same as the directory we're using as source.
Examples
Portion-based storage pool:
virsh pool-define-as main-storage-pool fs --source-dev /dev/sda7 --target /main-storage-pool
The corresponding XML is:
<pool type='fs'> <name>main-storage-pool</name> <source> <device path='/dev/sda7'/> </source> <target> <path>/main-storage-pool</path> </target> </pool>
Directory-based storage pool:
virsh pool-define-as iso-images dir --source-path /iso-images --target /iso-images
