我Nexus3被卡住，由于出空间的问题，我清理一些目录（非关系），并开始，它的显示状态如下图所示
# service nexus status;
? nexus.service - LSB: nexus
Loaded: loaded (/etc/init.d/nexus; generated)
Active: active (exited)
在日志中我可以看到下面

但是当我做LS它显示文件是存在的
root@XXX:/opt/nexus/sonatype-work/nexus3/db/component# ls -ltrh dirty.fl
-rw-r--r-- 1 root root 2 Feb 6 19:05 dirty.fl
任何线索，什么不顺心？
无法打开本地存储与模式 '的/ opt /关系/ Sonatype的工作/ nexus3 / DB /组件'= RW
该文件存在，但NXRM无法在读写模式下打开它。既然你已经跑出来的磁盘空间，请确保您的硬盘没有安装在只读模式。
如果你还在外面的空间，移动sonatype-work/nexus3/db/component目录到另一个位置，并创建一个符号链接指向新的组件目录。选择新位置时，请牢记性能。
为了防止这种情况再度发生，请尝试使用Cleanup Policies和定期运行Compact blob store任务。
