问题现象
巡检过程中发下1套11.2.0.4版本的RAC的生产环境服务上，/oracle目录空间仅剩余8.3G，需尽快清理大文件避免磁盘爆满宕机。

-rw-r----- 1 root root 53G 12月 29 10:50 /oracle/grid_home/crf/db/rac01/crfclust.bdb
问题原因
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)
Bug 20186278 – crfclust.bdb Becomes Huge Size Due to Sudden Retention Change (Doc ID 20186278.8)
ora.crf用途
资源对应的功能是CHM.Cluster Health Monitor（以下简称CHM）是一个Oracle提供的工具，用来自动收集操作系统的资源（CPU、内存、SWAP、进程、I/O以及网络等）的使用情况。CHM会每秒收集一次数据。这些系统资源数据对于诊断集群系统的节点重启、Hang、实例驱逐(Eviction)、性能问题等是非常有帮助的。另外，用户可以使用CHM来及早发现一些系统负载高、内存异常等问题，从而避免产生更严重的问题。
crfclust.bdb 文件是Oracle Cluster Health Monitor (CHM) 中 CRF 服务用于存储数据的文件，默认只存储一定时间数据，正常情况不会增长过大，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。
例如在11.2.0.4版本中，由于bug 10165314，ORA.CRF服务可能会生成很大的文件，这可能会对$GI_HOME的使用率造成压力。因此，在某些情况下可能需要删除这些文件或者禁止ORA.CRF随ohas启动而启动。
解决步骤
两节点依次清理，清理完一节点，再清理二节点
采用停止ora.crf资源—>删除crfclust.bdb文件—>启动ora.crf资源
获取CHM路径
--获取Cluster Health Monitor (CHM) 存储路径
[grid@rac01 bin]$ /oracle/grid_home/bin/oclumon manage -get reppath
CHM Repository Path = /oracle/grid_home/crf/db/rac02Done本次生产环境中获取Cluster Health Monitor (CHM) 存储路径提示如下：
[grid@rac01 bin]$ cd /oracle/grid_home/crf/db/rac02
-bash: cd: /oracle/grid_home/crf/db/rac02: No such file or directory
而虚拟机环境试了下可以获取，原因不详，继续往下分析[grid@rac01 bin]$ cd /oracle/grid_home/crf/db/rac01

有博主写：如果不想这么麻烦，也可以不用管服务，直接删除文件，crf会自动重建文件（亲测没有问题）。但是在实操中发现不停止crf资源，直接rm -f删除文件虽能成功删除，但是df -h查磁盘空间并没有释放，原因crf相关资源进程占用该文件导致空间不释放。建议还是停服务后再操作避免意外发生。
rm -f *.bdb
如果确认不需要该服务，可以禁用
crsctl modify resource “ora.crf” -attr “AUTO_START=0” -init

未释放磁盘空间原因：
在Linux或者Unix系统中，通过rm或者文件管理器删除文件将会从文件系统的目录结构上解除链接(unlink).然而如果文件是被打开的（有一个进程正在使用），那么进程将仍然可以读取该文件，磁盘空间也一直被占用。而我删除的是oracle的ora.crf资源的crfclust.bdb文件，删除的时候文件应该正在被使用 ，文件时间Dec 30 14:35 和当前的服务器时间吻合。
[root@rac01 rac01]# ls -lh /oracle/grid_home/crf/db/rac01/crfclust.bdb

进程释放
法一：kill掉相应的进程。
法二：停掉使用这个文件的应用，让os自动回收磁盘空间。
由于是生产环境，出于谨慎考虑，采用停止ora.crf资源—>删除crfclust.bdb文件—>启动ora.crf资源，磁盘空间释放成功。
