VM doubles the size after copy


Question

Thats definitely odd. Is your XenServer up to date on hotfixes? If it is too many behind it may be easier to upgrade.

If your original has 1 disk and the copy has two disks, sounds like you can remove the read only one to make the

size right. Something incomplete with the copy I am guessing.

Thanks for the reply.

 

I dig in more and found that two VDIs that are showing same size via command  xe vdi-list name-label=vmname as shown below are not same as in vdi-uuid.vhd you can see the image for reference.

Means the size utilization is  actual but the virtual allocation shows double.

 

Now  I have two doubts.

1. Why two disks, when migrated.

2. Can we fix this virtual allocation size problem.

 

# xe vdi-list name-label=vmname
uuid ( RO)                : 7b574a19-942b-4143-9738-634534c7da2e
          name-label ( RW): vmname
    name-description ( RW): description
             sr-uuid ( RO): 795d8b11-2722-57f3-2b81-cd91922d58bd
        virtual-size ( RO): 118111600640
            sharable ( RO): false
           read-only ( RO): true


uuid ( RO)                : 114b2f7f-a9fd-47db-9c27-27f4b2f8f14e
          name-label ( RW): vmname
    name-description ( RW): description
             sr-uuid ( RO): 795d8b11-2722-57f3-2b81-cd91922d58bd
        virtual-size ( RO): 118111600640
            sharable ( RO): false
           read-only ( RO): false

Yes, it should be one disk after migration. As long as their is ample space available the coalesce should work

if  that is indeed the issue. I haven't seen this behavior before myself.  As long as you are up to date on 

hotfixes see if the disks eventually merge back to one.
