31 TCMU-backed handlers are typically configured using normal LIO configuā
32 ration tools, such as targetcli. Part of doing this will be entering a
33 handler-specific configuration string.

35 CONFIGURING GLUSTER HANDLER (glfs)
36 This handler uses the Gluster glfs API to use Gluster as a backstore
37 for the image file.
38
39 Its configuration string is:
40
41 volume@hostname/filename
42 volume: The volume on the Gluster server
43 hostname: The server's hostname
44 filename: The backing file
45
46 CONFIGURING QCOW HANDLER (qcow)
47 This handler supports qcow, qcow2, or raw image file formats.
48
49 Its configuration string is:
50
51 path
52 path: The full path to a file of a supported file format. The file
53 must already have been created using qemu-img.
