Merge VHD

Hi,

I use cloudstack with XenServer and I would like to move some disks to another xenserver pool.
I would like to join the chain of disks and create a single vhd to move it. I'm doing some tests with a disk with an example chain:

vhd-util scan -f -m 8d430cda-c109-4c4b-acfd-3492b8f35cd7.vhd -p
vhd=8d430cda-c109-4c4b-acfd-3492b8f35cd7.vhd capacity=8589934592 size=20992 hidden=0 parent=f8ab7260-c1ae-4007-85ec-aa2ba4a04127.vhd (not found in scan)

I would like to create a new disk called merge.vhd that contain both vhd, and I tried to follow this:

https://shankerbalan.net/blog/recover-xenserver-vhd-volumes/

[root@xenser]# mkdir appo ; cp 8d430cda-c109-4c4b-acfd-3492b8f35cd7.vhd  f8ab7260-c1ae-4007-85ec-aa2ba4a04127.vhd appo ; cd appo
[root@xenser]# vhd-util coalesce -n 8d430cda-c109-4c4b-acfd-3492b8f35cd7.vhd

but I can not have a single file.

Thanks

Gian, I did that once, but I used the following command:
vhd-util coalesce -p -n <vhdUUID>.vhd –o /tmp/ <name>.vhd

You need the full chain of the '<vhdUUID>.vhd' in the folder you are
running this command

Hello Gian,

I would suggest just to copy vdi.

xe vdi-copy uuid= sr-uuid=

This will create new VDI in destination SR without VHD chain.

Gian, I did that once, but I used the following command:
vhd-util coalesce -p -n <vhdUUID>.vhd –o /tmp/ <name>.vhd

You need the full chain of the '<vhdUUID>.vhd' in the folder you are
running this command

Hello Gian,

I would suggest just to copy vdi.

xe vdi-copy uuid= sr-uuid=

This will create new VDI in destination SR without VHD chain.

Hi Gian Paolo,

Can you elaborate ? What are the errors you are seeing, what doesn’t work?
