AIX双机+oracle 扩充文件系统问题
请问为什么以下显示的/database大小不同？配置为双机，如何扩充/database文件系统？显示有FREE PP 1024,是在smitty hacmp中直接配置吗？是不是那个空间是Oracle 使用的裸设备？不能再扩容，需划分新的存储空间。

收起df -g是显示已分配的
lsfs没啥意义
你确定你这个/dev/fslv02在哪个vg 然后这个vg还有没有free pp 如果有你就扩充一下试试 chfs -a size=+1g /database 如果不能 请贴错误提示，一般是lv的maxpp数做了限制
收起不是并发文件系统。df -g 与lsfs显示不同，是不是有备份，下面显示COPIES:1.
那这样的话，是不是需要从存储上再挂存储？
