我有一个Cinder存储和控制器节点运行在与Nova计算机相同的CentOS 7盒子上。 一切正常，直到我重新启动。 现在，我的实例无法装入卷，我得到下面的错误。
dmesg的：

target.service启动时没有错误，而且我的iSCSIconfiguration没有使用ACL。 即使启用， cinder-scheduler和cinder-volume服务也处于closures状态。
我search了这个问题，发现了其他人，但没有解决scheme。 任何帮助表示赞赏！
将以下内容添加到存储节点上的/etc/cinder/cinder.conf ：
[DEFAULT] enabled_backends=lvm57 [lvm57] iscsi_helper=lioadm volume_group=cinder-volumes volume_driver=cinder.volume.drivers.lvm.LVMISCSIDriver iscsi_ip_address=192.168.186.168 volume_backend_name=LVM_iSCSI
