试图挂载磁盘(硬件raid)但失败了.
#mount -t ext4 /dev/sda /data
mount: wrong fs type,bad option,bad superblock on /dev/sda,missing codepage or helper program,or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
#dmesg | tail -1
EXT4-fs (sda): VFS: Can't find ext4 filesystem
我究竟做错了什么？
我看到许多有类似问题的海报都要求发布fstab的内容,所以这里是：
#cat /etc/fstab # # /etc/fstab # Created by anaconda on Wed Aug 6 11:29:15 2014 # # Accessible filesystems,by reference,are maintained under '/dev/disk' # See man pages fstab(5),findfs(8),mount(8) and/or blkid(8) for more info # UUID=276c97cc-9c5f-496f-a56f-ac3a45c58a26 / ext4 defaults,usrquota,grpquota 1 1 UUID=3978f122-03d4-48db-adeb-6fc8a2c624c4 /boot ext2 defaults 1 2 UUID=1251c6d8-c417-48df-9cf4-2f56e3a823a6 /tmp ext4 defaults 1 2 UUID=95fd67df-7172-4ac9-9264-0b50819a203a swap swap defaults 0 0 tmpfs /dev/shm tmpfs defaults 0 0 devpts /dev/pts devpts gid=5,mode=620 0 0 sysfs /sys sysfs defaults 0 0 proc /proc proc defaults 0 0

解决方法
使用mount时,必须安装分区而不是驱动器本身,例如mount -t ext4 / dev / sda1 / data
