[one-users] OpenNebula didn't delete the disk.id file when I detach the disk from VM

[zouxinzhe]

I have modify the script to remove the file disk.* whenever I detach it. Now everything seems well.
But I wonder if this problem will reproduce when I upgrade my OpenNebula in the future?

Let us know if this works for you... note that in your case you may need to modify the delete script from the lvm drivers...

Hi，there are some other question I have.
I wanna attach a disk to my VM.I have create a image in LVM datastore : 
oneimage create -d 100 --name volume1 --type DATABLOCK --size 1024 --fstype ext4
All is OK.Then I use this image to attach a disk to a VM :
onevm attachdisk one-12 --image volume1 --target vdaa
The OpenNebula has make a snapshot and ln this snapshot to the disk.2. However when I detach the disk from VM, OpenNebula remove the lv but it doesn't remove the disk.2.
So it will be fail when I try to attach another disk to that VM, following is the error log:
ln -s "/dev/vg_node176/lv-one-13-12-2" "/opt/nebula/ONE/var/datastores/0/12/disk.2"" failed: ln: creating symbolic link `/opt/nebula/ONE/var/datastores/0/12/disk.2': File exists
Is that a BUG?
