由于客户使用redhat6.9 acfs文件系统,并且/u01/ogg目录才100g,空间不足，需要扩容。
因此测试环境进行测试，后续生产环境进行扩容。
一、测试

二、生产环境扩容

VOLUME_NAM SIZE_MB REDUND STATE VOLUME_DEVICE
---------- ---------- ------ --------------- --------------------

······
Usage: ACFS
Mountpath: /u01/ogg

实际上确认acfs挂载目录，以及确认存储空间足够，直接size 即可，非常方便。
本次上面有ogg进程，先stop *,stop mgr 关闭ogg进程后进行操作，扩容200g,1分钟不到。
grid$acfsutil size 300G /U01/ogg
