挂载错误，特殊设备不存在

我有一个Linux Debian服务器：

Distributor ID: Debian Description: Debian GNU/Linux 7.1 (wheezy) Release: 7.1 Codename: wheezy

我有一些硬件设备连接到我的服务器，在我的系统中安装在不同的目录中。每一件事情都可以正常工作，直到一台设备从服务器上被拔掉而没有被无视。再次连接设备后，我厌倦了安装它：这是我的/etc/fstab文件内容（这是设备的第一个configuration，它曾经工作）：

 /dev/cciss/c0d1p1 /var/www/vhosts/ ext4 defaults,acl 0 1 /dev/cciss/c0d2p1 /home/samba/ ext4 defaults,acl 0 1

我的cciss设备包含:( ls /dev/cciss/ ）

 c0d0 c0d0p1 c0d0p2 c0d0p5 c0d1 c0d2 c0d2p1

我想挂载/dev/cciss/c0d1p1所以我试过了：

 mount /dev/cciss/c0d1p1

我得到这个输出：

 mount: special device /dev/cciss/c0d1p1 does not exist

fdisk -l显示/dev/cciss/c0d1没有项目也blkid给了我：

 /dev/cciss/c0d0p5: UUID="4d144db1-bypl-43d0-b5cb-e857ab8b7f14" TYPE="swap" /dev/cciss/c0d2p1: UUID="d0fdfteb-e9eb-4t8c-bf5e-374613e29btr" TYPE="ext4" /dev/cciss/c0d0p1: UUID="78sa9u1d-8d17-44be-9116-758ez1k24d27" TYPE="ext4"

我试过fdisk -l /dev/cciss/ ，它给了我这个输出：

 last_lba(): I don't know how to handle files with mode 40755

在读取设备/dev/cciss/c0d1期间， pvs -a显示错误。输出：

  /dev/cciss/c0d1: read failed after 0 of 4096 at 0: Input/output error /dev/cciss/c0d1: read failed after 0 of 4096 at 750122696704: Input/output error /dev/cciss/c0d1: read failed after 0 of 4096 at 750122811392: Input/output error /dev/cciss/c0d1: read failed after 0 of 4096 at 4096: Input/output error PV VG Fmt Attr PSize PFree /dev/cciss/c0d0p5 --- 0 0 /dev/cciss/c0d1 --- 0 0 /dev/cciss/c0d2p1 --- 0 0 /dev/root --- 0 0

我不太了解这个问题，但我认为一旦设备断开连接，就必须再次重新configuration，在安装设备之前我必须定义分区。我想也许在我的情况下VolumeGroup名称将是错误的，所以我试过： lvscan ：

  /dev/cciss/c0d1: read failed after 0 of 4096 at 0: Input/output error /dev/cciss/c0d1: read failed after 0 of 4096 at 750122696704: Input/output error /dev/cciss/c0d1: read failed after 0 of 4096 at 750122811392: Input/output error /dev/cciss/c0d1: read failed after 0 of 4096 at 4096: Input/output error No volume groups found

也pvscan; vgchange -ay pvscan; vgchange -ay给了我：
