7       User backstore

DESCRIPTION

10       tcmu-runner is a service that provides an operating environment for LIO
11       TCM-User  handlers.  These  currently include handlers for Gluster glfs
12       and the qcow and qcow2 image formats.

17       runner  can  also  be  run  as root directly, usually for debugging and
18       development purposes.

CONFIGURING HANDLERS

32       TCMU-backed handlers are typically configured using normal LIO configuā€
33       ration tools, such as targetcli.  Part of doing this will be entering a
34       handler-specific configuration string.
35
36   CONFIGURING GLUSTER HANDLER (glfs)
37       This handler uses the Gluster glfs API to use Gluster  as  a  backstore
38       for the image file.
39
40       Its configuration string is:
41
42           volume@hostname/filename
43           volume: The volume on the Gluster server
44           hostname: The server's hostname
45           filename: The backing file
46
47   CONFIGURING QCOW HANDLER (qcow)
48       This handler supports qcow, qcow2, or raw image file formats.
49
50       Its configuration string is:
51
52           path
53           path:  The full path to a file of a supported file format. The file
54           must already have been created using qemu-img.
