[问题解决]Stderr: u’/usr/bin/cinder-rootwrap: Executable not found: tgtadm (filter match = tgtadm)\n’

近期又开始折腾Openstack，按照官网安装完成最小测试集群后。开始使用后，使用cinder创建卷成功以后，无法将卷挂载到实例上。查看错误日志，出现提示如下：Stderr: u'/usr/bin/cinder-rootwrap: Executable not found: tgtadm (filter match = tgtadm)\n'

安装环境

• CentOS7.3 1611
• Openstack ocata版本

解决过程

1.安装epel-release

rpm -ivh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

2.安装scsi-target-utils

yum install -y scsi-target-utils

3.修改配置文件/etc/tgt/tgtd.conf，增加以下内容

# 以下路径和cinder配置路径相同
include /var/lib/cinder/volumes/* 

4.启动

systemctl enable tgtd
systemctl start tgtd    

5.重启cinder

systemctl restart openstack-cinder-volume.service target.service
