问题解决过程如下:
查看文件系统是否已挂载:
ebdbpro:/ # df -h
Filesystem Size Used Avail Use% Mounted on

mount文件系统报错:
ebdbpro:/ # mount /dev/mapper/oraclevg-oraclelv /eb_db

查看文件系统分区表:
ebdbpro:/ # more /etc/fstab
修复文件系统:
ebdbpro:/ # fsck -t ext3 /dev/mapper/oraclevg-oraclelv

简单来说:
运行挂载命令如 mount /dev/sdb1 mnt出现错误:
mount: wrong fs type, bad option, bad superblock on /dev/sdc1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so.
检查该磁盘的文件系统,即运行命令
fsck -t ext4 /dev/sdb1
上面的选项“ -t ext4 ”表示文件系统类型为 ext4.
