docker启动es报错：failed to obtain node locks...

在学习es时，使用docker启动时发现一直报错：

java.lang.IllegalStateException: failed to obtain node locks, tried [[/usr/share/elasticsearch/data]] with lock id [0]; maybe these locations are not writable or multiple nodes were started without increasing [node.max_local_storage_nodes] (was [1])?
Likely root cause: java.nio.file.AccessDeniedException: /usr/share/elasticsearch/data/nodes/0/node.lock

查找文章：
（1）node.lock被其他进程使用了，这也是网上大多数的解释。解决方案呢，首先查看es的进程，然后杀掉。
ps aux | grep elastic

kill -9 [pid]

然而我的并没有进程占用
（2）有篇文章写的是目录权限不对

我的docker启动命令是

docker run -d \--name es \-e "ES_JAVA_OPTS=-Xms512m -Xmx512m" \-e "discovery.type=single-node" \-v es-data:/usr/share/elasticsearch/data \--privileged \--network es-net \-p 9200:9200 \-p 9300:9300 \
elasticsearch:7.12.1

使用-v参数把docker里的/usr/share/elasticsearch/data 目录挂载到了宿主机的es-data目录里，所以猜测是这个数据卷的问题，把-v参数删掉，再次run发现就可以运行成功了。

原因：找到宿主机挂载的这个数据卷目录,发现nodes目录不知道为什么是101账号，
docker inspect es-data
把这个数据卷的nodes目录删了再重启即可成功，如果不行就把整个数据卷目录删了重试
