crfclust.bdb : Grid Infrastructure Disk Space Problem – CHM DB file

Recently, I have come across an issue in 11gR2 RAC (11.2.4), where the GI file system GRID_HOME was mostly consumed by a single file called crfclust.bdb .
crfclust.bdb is a Cluster Health Monitor (CHM) file, which collects the stats of Cluster as well as the OS statistics by means of the Cluster Health Monitor Service ora.crf.
 I have resolved by resize it as following commnads:

1-# df -h

 Size  Used Avail Use% Mounted on
/dev/mapper/vg_emsdb1-LogVol00
                       99G   85G   9G  90% /


[root@node1]# cd /grid/product/11.2.0/grid_1/bin/
[root@node1 bin]# ./oclumon manage -get repsize

CHM Repository Size = 39688312


 Done

2- Change the repository size to the desired number of seconds, between 3600 (1 hour) and 259200 (3 days).on node1 and node2  we'll change repository retention size:

[root@node1 bin]# ./oclumon manage -repos resize 259200
node1 --> retention check successful
node2 --> retention check successful
New retention is 259200 and will use 4524595200 bytes of disk space

CRS-9115-Cluster Health Monitor repository size change completed on all nodes.

 Done

3- on node1 and node2 stop and start ora.crf source:

[root@node1 bin]# ./crsctl stop res ora.crf -init
CRS-2673: Attempting to stop 'ora.crf' on 'node1'
CRS-2677: Stop of 'ora.crf' on 'node1' succeeded

[root@node1 bin]# ./crsctl start res ora.crf -init
CRS-2672: Attempting to start 'ora.crf' on 'node1'

CRS-2676: Start of 'ora.crf' on 'node1' succeeded

4-
[root@node1 bin]# ./oclumon manage -get repsize

CHM Repository Size = 259200

 Done

[root@node2 bin]# ./oclumon manage -get repsize


CHM Repository Size = 259200

 Done

5- Check your root / size:

df -h

 Size  Used Avail Use% Mounted on
/dev/mapper/vg_emsdb1-LogVol00

                       99G   31G   63G  33% /
