紧急求助，无法 mount 分区

[dong.yajun]

各位大神，有一个分区在fdisk -l 时，可以显示：

Disk /dev/sdm: 2000.3 GB, 2000398934016 bytes

255 heads, 63 sectors/track, 243201 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System

/dev/sdm1               1      243201  1953512001   83  Linux

但mount的时候，一直失败 ：

[root@node13 ~]# mount -l /dev/sdm1 /sd12

mount: /dev/sdm1 already mounted or /sd12 busy

说是已经mount了，但df 下 看不到 /dev/sdm1

是比较奇怪，你mount时的报错是什么？

[dong.yajun]

mount 的时候，报：

mount: /dev/sdm1 already mounted or /sd12 busy

说是已经被mount了，还有就是/sd12忙，但/sd12只是一个用于/dev/sdm1挂的目录而已

[dong.yajun]

似乎和这个有点像，但不知道evms package 是什么，指点一下呢：

我的/var/log/message下面也有

Sep 30 03:19:12 node13 kernel: device-mapper: table: 253:1: linear: dm-linear: Device lookup failed

Sep 30 03:19:12 node13 kernel: device-mapper: ioctl: error adding target to table

dm映射的时候出问题了？

试着手动映射？
