Step 7 as you've written it is not correct. You have to mount the logical volume, not the image file!
Code:
mount /dev/xen-vm/xen_prov /FMW/xen_vm

And I hope that this is only for experimenting with LVM, since a loopback device will not be re-created automatically after a reboot, and thus can't be automatically be mounted during startup. This is why I suggested that you use the whole of sdb1 if possible.

yes just saw once rebooted all vanished Smilie. i am not entitled to use the whole of sdb1 which is 1T, i have only got 500 G of that, thats why.

can;t that be mounted on /etc/fstab for permanent addition ?

Lets take a step back here and look at the complete picture. You have a 1TB drive/partition, on which you should create a 500G filesystem for use with Xen. What about the rest of the drive? Is this reserved for a different project? If so, could that project also use LVM? If not, would it be possible to re-partition the drive?

Thanks for your help pludi.

No 500 GB is for another team, so could only use 500gb of it,

But you know, what i could do is i needed the 500 GB for xen virtualistaion

So heres what i did:

Created the disk image using dd :
Quote:
# dd if=/dev/zero of=/FAW/vms/linux_vm/disk2.img bs=1 count=1024 seek=500G
Quote:
added the image to vm.cfg config file

Booted on Linux guest console and from there i created parition use fdisk

fdisk /dev/sdf , then pvcreate , vgcreate,lvcreate, mkfs.ext3, mounted the partion.

and then added to /etc/fstab.
thanks again!
