cinder 配置 安装：
1） 下载source code
2） pip install
3） yum install scsi-target-utils
4） yum install iscsi-initiator-utils.x86_64 (这两个相当于ubuntu下的 open-iscsi和tgt）
5） edit cinder config file
normally it includes :
database config
keystone access config
volumes config
message queue config
also enable cinder api in nova.conf
6) edit
/etc/lvm/lvm.conf
Add volume_list entry to /etc/lvm/lvm.conf to keep LVM from activating logical volumes created in VMs.
volume_list = [“VolGroup”, “cinder-volumes” ]
volume_list should include your os related volume group.
7）add volumes dir in /etc/tgt/targets.conf
include /var/lib/cinder/volumes/*
8) restart tgtd service
9) init cinder db
cinder-manage db sync
10) test if cinder works
10.1 create one test loop file and mount it
dd if=/dev/zero of=cinder-volumes bs=1 count=0 seek=2G
losetup /dev/loop2 cinder-volumes
10.2 init pv and create vg
pvcreate /dev/loop2
vgcreate cinder-volumes /dev/loop2
10.3 check if volume is created
pvscan
10.4 restart cinder service:
cinder api, scheduler, volume
10.5 use cinder to create volume
cinder create –display_name test 1
10.6 verify volume created successfully
cinder list
volume should in “available” status
