linux Inodes满导致数据库宕机

项目经理反馈集群环境中有个节点无法使用了需要支援下，同时发过来截图说明磁盘还是有空的。

登录系统后直接发现问题

orcl2:/home/oracle@db2> sqlplus / as sysdba

ERROR:
0RA-09925:Unable to create audit trail file
Linux-x86 64 Error: 28:No space left on device
Additional information: 9925
ORA-01075:you are currently logged on   

该类问题还是较为容易看到问题点，肯定是*.aud文件太多导致的问题

[root@db2 ~]#  df -i

处理办法：

  #  find /u01/app/grid/product/11.2.0/grid_1/rdbms/audit/  -name "*.aud"  -mmin +0 | xargs rm -rf "*.aud"
  #  find /u01/app/oracle/admin/orcl/adump/  -name "*.aud"  -mmin +0 | xargs rm -rf "*.aud"
