.SH COMMANDS
.SS "Volume Commands"
.PP
.TP
\fB\ volume info [all|<VOLNAME>] \fR
Display information about all volumes, or the specified volume.
.TP
\fB\ volume create <NEW-VOLNAME> [device vg] [stripe <COUNT>] [replica <COUNT>] [transport <tcp|rdma|tcp,rdma>] <NEW-BRICK> ... \fR
Create a new volume of the specified type using the specified bricks and transport type (the default transport type is tcp).
To create a volume with both transports (tcp and rdma), give 'transport tcp,rdma' as an option.
device vg parameter specifies volume should use block backend instead of regular posix backend. In this case NEW-BRICK should specify an existing Volume Group and there can be only one brick for Block backend volumes. \fR
Refer Block backend section for more details
.TP
\fB\ volume delete <VOLNAME> \fR
Delete the specified volume.
.TP
\fB\ volume start <VOLNAME> \fR

By specifying "device vg" in volume create, a volume capable of exporting block devices(ie Volume Groups (VG)) is created. As of now exporting only VG is supported. While creating block backend volume the "VG" (mentioned in NEW-BRICK) must exist (ie created with vgcreate). VG is exported as a directory and all LVs under that VG will be exported as files. Please refer BD commands section for Block backend related commands
