nexus报错

1.

Error occurred while executing a write operation to database 'component' due to limited free space on the disk (3748 MB). The database is now working in read-only mode. Please close the database (or stop OrientDB), make room on your hard drive and then reopen the database. The minimal required space is 4096 MB. Required space is now set to 4096MB (you can change it by setting parameter storage.diskCache.diskFreeSpaceLimit)

原因：这个错误是由于在尝试对名为’component’的OrientDB数据库执行写操作时，发现磁盘上的可用空间不足而引起的。错误消息表明磁盘上的可用空间不足以使数据库正常运行。OrientDB默认的最小空闲磁盘是4096M

处理：

1.可以在修改参数调小参数将OrientDB由默认的4096M改成1024M

vim bin/nexus.vmoptions

-Dstorage.diskCache.diskFreeSpaceLimit=1024

2.扩盘
