Symptoms

Filesystem utilisation on /opt/oracle is excessive on  storage cells:

[root@dbadm01 ~]# dcli -l root -g cell_group 'df -h /opt/oracle' | grep oracle
celadm011: /dev/md8 3.0G 2.3G 527M 82% /opt/oracle
celadm021: /dev/md8 3.0G 2.1G 801M 73% /opt/oracle
celadm031: /dev/md8 3.0G 2.0G 841M 71% /opt/oracle
celadm041: /dev/md8 3.0G 2.5G 374M 87% /opt/oracle
celadm051: /dev/md8 3.0G 2.1G 744M 75% /opt/oracle
celadm061: /dev/md8 3.0G 2.0G 837M 71% /opt/oracle
celadm071: /dev/md8 3.0G 2.1G 723M 75% /opt/oracle

Drilling down we see the following directory is the main candidate:

[root@dbadm01 ~]# dcli -l root -g cell_group 'du -sm /opt/oracle/cell/cellsrv/deploy/config/metrics'
celadm011: 1421 /opt/oracle/cell/cellsrv/deploy/config/metrics
celadm021: 1148 /opt/oracle/cell/cellsrv/deploy/config/metrics
celadm031: 1107 /opt/oracle/cell/cellsrv/deploy/config/metrics
celadm041: 1574 /opt/oracle/cell/cellsrv/deploy/config/metrics
celadm051: 1205 /opt/oracle/cell/cellsrv/deploy/config/metrics
celadm061: 1111 /opt/oracle/cell/cellsrv/deploy/config/metrics
celadm071: 1226 /opt/oracle/cell/cellsrv/deploy/config/metrics
