在运行 14.04 的多节点 Kilo Openstack 上，我无法将 Cinder 卷附加到实例。以下是我采取的步骤：
1- 创建 100G 环回设备，
$ sudo losetup -a
/dev/loop0: [0801]:35136386 (/var/lib/cinder/volumes/vol1.img)
2-创建分区并将其附加到 cinder-volumes：
# pvdisplay

3-创建5G卷

4-尝试通过 Horizon 将其附加到正在运行的实例，以下是我从 Cinder 日志文件中获得的内容：

有几件事很突出：
1-卷的持久文件已经存在...，这听起来像是时间问题
2-查看安装了 Cinder 的控制机器，tgt-admin，最初消耗了大量的 CPU 和内存：
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND

138 root 20 0 0 0 0 S 16.5 0.0 3:05.25 kswapd0
，可能与此消息有关：Stdout: u"Unexpected error while running command.\nCommand: sudo cinder-rootwrap /etc/cinder/rootwrap.conf tgt-admin --update iqn.2010-10.org.openstack:volume-6b50b07b-79b6-4733-9049-531b5d68dae5\nExit code: 1\nStdout: u''\nStderr: u'Out of memory!\\n'"
