Nexus3处于活动状态(已退出)，不可访问

Question

由于空间外问题，我的Nexus3被卡住了，我清理了一些目录(非附件)并启动，其显示状态如下所示

# 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

但是当我这么做的时候，它显示了文件在那里。

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

有什么线索吗？

无法用'/opt/nexus/sonatype-work/nexus3/db/component‘打开本地存储mode=rw

文件是存在的，但是NXRM不能在读写模式下打开它.由于您的磁盘上的空间已经耗尽，请确保您的磁盘没有以只读模式挂载。

如果您仍然没有空间，请将sonatype-work/nexus3/db/component目录移到另一个位置，并创建一个指向新组件目录的符号链接。在选择你的新地点时，要记住你的表现。

为了防止将来发生这种情况，请尝试使用清理政策并定期运行紧凑型水滴商店任务。
