[Solved] Issue: crfclust.bdb file is too large

Fui acionado certa vez por um FS quase estourado, e percebi que o arquivo ofensor era o “crfclust.bdb”, com 12GB de tamanho:

[grid@oel6 oel6]$ pwd
/apl/grid/11.2.0/product/crf/db/oel6
[grid@oel6 oel6]$ du -hs *
227M    crfalert.bdb
12G     crfclust.bdb
8.0K    crfconn.bdb
227M    crfcpu.bdb
222M    crfhosts.bdb

Encontrei um Oracle Note reportando um problema conhecido e o procedimento de resolução: Oracle Cluster Health Monitor (CHM) using large amount of space (more than default) (Doc ID 1343105.1). Link AQUI.

Baixando o serviço CRF:

[grid@oel6 oel6]$ cd $ORACLE_HOME/bin
[grid@oel6 bin]$ pwd
/apl/grid/11.2.0/product/bin
[grid@oel6 bin]$ sudo /apl/grid/11.2.0/product/bin/crsctl stop res ora.crf -init
CRS-2673: Attempting to stop 'ora.crf' on 'oel6'
CRS-2677: Stop of 'ora.crf' on 'oel6' succeeded
[grid@oel6 bin]$

Removendo todos os arquivos com extensão “.bdb”:

[root@oel6 oel6]# rm *.bdb
rm: remove regular file `crfalert.bdb'? y
rm: remove regular file `crfclust.bdb'? y
rm: remove regular file `crfconn.bdb'? y
rm: remove regular file `crfcpu.bdb'? y
rm: remove regular file `crfhosts.bdb'? y
rm: remove regular file `crfloclts.bdb'? y
rm: remove regular file `crfts.bdb'? y
rm: remove regular file `repdhosts.bdb'? y

Subindo novamente o serviço:

[grid@oel6 oel6]$ cd $ORACLE_HOME/bin
[grid@oel6 bin]$ sudo /apl/grid/11.2.0/product/bin/crsctl start res ora.crf -init
CRS-2672: Attempting to start 'ora.crf' on 'oel6'
CRS-2676: Start of 'ora.crf' on 'oel6' succeeded
[grid@oel6 bin]$

Ambiente normalizado. Os arquivos removidos foram recriados após o start do serviço:

[grid@oel6 bin]$ cd /apl/grid/11.2.0/product/crf/db/oel6
[grid@oel6 oel6]$ ll
