grid所在目录空间满

[root@wldb01 ~]# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/sdw2              40G   22G   17G  58% /
tmpfs                  16G  219M   16G   2% /dev/shm
/dev/sdw1              50G   46G  1.5G  97% /u01

使用find命令找出来大文件

[root@wldb01 grid]# find ./ type f -size +1024M
./crf/db/wldb01/crfclust.bdb

由于文件crfclust.bdb是Cluster Health Monitor (CHM) file,他的默认大小是1G,但是有在一些平台和版本中由于bug原因导致过大.
Oracle Cluster Health Monitor (CHM) using large amount of space (more than default) (Doc ID 1343105.1)
