Hi，
A message On's not done.
Attach disk to virtual machine also have a problem, as below:
onevm detachdisk one-27 2
Detach just attach the disk file from virtual machine，found on the node where the VM to detach the actual files not be deleted。

And then, again attach the image disk to virtual machine, attach failed logs as follows:

Because the original disk file is not deleted before attaching， at the same time，It had the same problem use LVM Storage for testing。
After detachdisk In the LVM storage, disk.2 file ln points to LVM volume is real deleted。lvs command execution are able to see the volume。 but the disk point link still exists。 so， Attach also have a problem again.
Ask what is the reason， and the design is a problem ？
Thanks！

Hi Ruben, André
After my tests, It can be mounted successfully when use the following command：
onevm attachdisk one-27 --image datablock_ext4 --target vdaa
specification：--target can't directly write "vd"， instead，such specific device name vdd or vdaa.
vm.log：

Hi Ruben,,
In fact, when I made the modification the TYPE expression was getting void, but now I tested it and now it has values. Go figure :-).

OK,
So David, your attach file is right. So, as André pointed out it may be a problem of specifying the right DEV_PREFIX (vd, sd). Can you perform the attach operation when setting the right target?
André, also I can't see the effect of your modifications for the attach script, after setting up TYPE there is a switch with a default, is that not being executed in your case?
Cheers

Hi
So as a summary, it seems that if target is not specified there is no default_prefix set for the image, and that is missing from Sunstone?
David, could you send the contents of disk.2.attach file please?
Thanks
Ruben

Hi,
I was executing from Sunstone. From the command line it also failed if no target is supplied. I ran

And it attached well the disk!

Hi,
I added the default type value according to what you said, but the problem truly exist.
Output the default type value is raw, before modification the value is file. Error did not change. are you no problem？
the TARGET arg is "sda" and do you know why?

主题: Re: [one-users] Attachdisk image to VM failed
Hi,
I had the same problem on 3.6 and sent to user list, but no answer. The problem is on /var/tmp/one/vmm/kvm/attach_disk, the code expression doesn't get a value. Go to line 50 and add a default type to bus like:
TYPE="raw"
TYPE=$(echo "$TYPE"|tr A-Z a-z)
and leave the other expression also to override if it is not empty.
