Re: [Xen-users] missing logical device

[SpiegelEiXXL <spiegeleixxl@xxxxxxxxxxxxxxx>]

Hello.

Can you check the output of
lvm pvdisplay
to see if LVM actually started/added the drive(s)?
Did you also try a lvmdiskscan / lvscan ?
the lvm should usually be mapped due when you boot into your system. Maybe something went wrong.
Can you also check /dev/mapper/ and /dev/XVG?

I am putting up a guest OS on a VM and created the LOGICAL DEVICES as shown in the etc/fstab as shown below:

[root@virtualintranet /]# cat etc/fstab

/var/swap/swap.001          swap      swap   defaults   0  0

none        /dev/shm  tmpfs  defaults   0  0

none        /proc     proc   defaults   0  0

none        /sys      sysfs  defaults   0  0

/opt/xensource/packages/iso/XenCenter.iso   /var/xen/xc-install   iso9660   loop,ro   0  0

/dev/XVG/root        /xen      ext3  defaults   0  0

/dev/XVG/r        /xen/domU      ext3  defaults   0  0

 

On restarting the server I tried to mount them again

[root@virtualintranet /]# mount xen/

mount: special device /dev/XVG/root does not exist.

I wonder what made my devices disappear and how can I reinstate them? Is there anything I missed like storage parameters during the setting up.
