安装错误，特殊设备不存在

2024-5-29 • tag-icon

我有一个 Linux Debian 服务器：

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

我的服务器上连接了一些硬件设备，它们安装在系统中的不同目录中。一切正常，直到设备从服务器上物理拔出而没有被解除。再次连接设备后，我尝试安装它：这是我的/etc/fstab文件内容（这是设备的第一次配置，它曾经工作过）：

/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

我想安装/dev/cciss/c0d1p1所以我尝试了：

mount /dev/cciss/c0d1p1

我得到了这个输出：

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

fdisk -l显示没有条目/dev/cciss/c0d1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"

我尝试了一下fdisk -l /dev/cciss/并得到了这个输出：

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

pvs -a读取设备时显示错误/dev/cciss/c0d1。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/c0d2p1          ---     0     0 
  /dev/root                  ---     0     0

我不太明白这个问题，但我认为一旦设备断开连接，就必须重新配置，并且必须在安装设备之前定义分区。我想也许在我的情况下 VolumeGroup 名称是错误的，所以我尝试了 : 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 4096: Input/output error
  No volume groups found

还给pvscan; vgchange -ay了我：

  /dev/cciss/c0d1: read failed after 0 of 4096 at 750122696704: Input/output error
