OpenStack灰烬:重启后iSCSI登录协商失败
OpenStack灰烬:重启后iSCSI登录协商失败
提问于 2015-02-02 19:52:44
我有一个灰烬存储和控制器节点运行在与Nova计算相同的CentOS 7框上。一切正常，直到我重新启动。现在，我的实例无法挂载卷，我得到了下面的错误。
dmesg：
[ 923.546115] scsi5 : iSCSI Initiator over TCP/IP

我已经找到了其他有这个问题的人，但没有解决办法。任何帮助都是非常感谢的！

将以下内容添加到存储节点上的/etc/cinder/cinder.conf中：
[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_iSCSIhttps://ask.openstack.org/en/question/55529/couldnt-start-any-instances-after-cinder-rebooted/
