A few months ago I have setup a server with three hard disks. The partition mapping the disks as follows:
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
As you can see I have created a Linux LVM file system. This are the information of the LVM Logical volume:
--- 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
Now I have the following problem the LVM file system don't mount properly.
If I open the mount point I see only a few files of the LVM disk. If I want to unmount the disk I get the following error:
umount /data/
umount: /data/: not mounted
If I want to mount the volume I get the following error:
mount -a
mount: /dev/mapper/gegevens-Data already mounted or /data busy
Wat is the problem here?
Thank you,
Ivo Trompert
