一、问题描述

在centos系统通过df  -h 报/dev/mapper/vg_centos6-lv_root分区磁盘占满100%，应用启动报各种异常错误"oracle.net.ns.NetException: Listener refused the connection with the following error...ORA-12505, TNS:listener does not currently know of SID given in connect descripto..org.apache.commons.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory (Listener refused the connection with the following error.."，如下日志所示

二、解决方法

1、通过cat  /etc/fstab查看最近挂载磁盘分区目录详情

#@b@# /etc/fstab@b@# Created by anaconda on Wed Aug  8 23:39:30 2018@b@#@b@# Accessible filesystems, by reference, are maintained under '/dev/disk'@b@# See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info@b@#@b@...@b@/dev/sda2               /data210202             ext4    defaults        0 0

2、因本来挂载磁盘容量最大50G，系统空间完全够了，肯定用户空间最近挂载大的磁盘分区目录等等。。。删除后解决问题
