我再也无法在Docker中创建和运行新容器了.但同时可以运行以前创建的容器.

当我尝试做这样的事情时:

[user@host ~ ] docker run --name=fpm-5.3 debian:jessie
2014/07/12 07:34:08 Error: Error running DeviceCreate (createSnapDevice) dm_task_run failed

来自docker.log:

2014/07/12 05:57:11 POST /v1.12/containers/create?name=fpm-5.3
[f56fcb6f] +job create(fpm-5.3)
Error running DeviceCreate (createSnapDevice) dm_task_run failed
[f56fcb6f] -job create(fpm-5.3) = ERR (1)
[error] server.go:1025 Error: Error running DeviceCreate (createSnapDevice) dm_task_run failed
[error] server.go:90 HTTP Error: statusCode=500 Error running DeviceCreate (createSnapDevice) dm_task_run failed

dmsetup状态

docker-8:1-1210426-pool: 0 209715200 thin-pool 352 2510/524288 205173/1638400 - ro discard_passdown queue_if_no_space 

但它们在磁盘上有很多可用空间.

我需要回复这样的事情:

echo "<a href="#">$some['variable']</a>

如何[]在链接中转义括号以回显变量？
