几个月前,我已经设置了一个带有三个硬盘的服务器。映射磁盘的分区如下:
Disk /dev/sda: 1000.2 GB, 1000204886016 bytes
255 heads, 63 sectors/track, 121601 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x7ca36fee
   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1       12158    97659103+  83  Linux
/dev/sda2           12159       13131     7815622+  82  Linux swap / Solaris
/dev/sda3           13132      121601   871285275    5  Extended
/dev/sda5           13132      121601   871285243+  8e  Linux LVM
Disk /dev/sdc: 1000.2 GB, 1000204886016 bytes
255 heads, 63 sectors/track, 121601 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x000160d1
   Device Boot      Start         End      Blocks   Id  System
/dev/sdc1               1      121601   976760001    5  Extended
/dev/sdc5               1      121601   976759969+  8e  Linux LVM
Disk /dev/sdb: 1000.2 GB, 1000204886016 bytes
255 heads, 63 sectors/track, 121601 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x0008d423
   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1               1      121601   976760001    5  Extended
/dev/sdb5               1      121601   976759969+  8e  Linux LVM
如您所见,我已经创建了一个Linux LVM文件系统。这是LVM逻辑卷的信息:
--- Logical volume ---
LV Name                /dev/gegevens/Data
VG Name                gegevens
LV UUID                XsddGq-i3wO-HjTg-Lafe-TSF3-28kr-FGYhRd
LV Write Access        read/write
LV Status              available
# open                 1
LV Size                2.63 TB
Current LE             689648
Segments               3
Allocation             inherit
Read ahead sectors     auto
- currently set to     256
Block device           252:0
现在我有以下问题LVM文件系统无法正确安装。
如果我打开挂载点,我只看到LVM磁盘的几个文件。如果我想卸载磁盘,我会收到以下错误:
umount /data/
umount: /data/: not mounted
如果我想挂载卷,我会收到以下错误:
mount -a
mount: /dev/mapper/gegevens-Data already mounted or /data busy
扫管笏是这里的问题?
谢谢,
