Subject [jira] [Created] (CLOUDSTACK-6146) subsequent migration fails as cloud stack renames files after 1st migration
Date Thu, 20 Feb 2014 08:24:19 GMT
praveena palaniswamy created CLOUDSTACK-6146:
------------------------------------------------

             Summary: subsequent migration fails as cloud stack renames files after 1st migration
                 Key: CLOUDSTACK-6146
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-6146
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the default.)
    Affects Versions: 4.3.0
         Environment: ESXi 5.5
            Reporter: praveena palaniswamy
             Fix For: 4.3.0


CLoudplatform/Cloudstack, renames the files after first successful migration and therefore,
subsequent migration fails. This happens with 
CloudPlatform 4.3
Hypervisor: ESXi5.5

1.	File name gets renamed after migration, which inturn fails subsequent migrations (CLOUDSTACK
issue)
a.	Before migration of data disk the contents of VM folder can be seen below
[root@host148 i-2-3-VM]# ls -l
total 40060
-rw-------. 1 root root 3221225472 Feb 13  2014 7868703c4e8345a58d568ece092baa0e-flat.vmdk
-rw-------. 1 root root        518 Feb 13 06:05 7868703c4e8345a58d568ece092baa0e.vmdk
[root@host148 i-2-3-VM]#

b.	After migration, cloudstack renames the file name 7868703c4e8345a58d568ece092baa0e.vmdk
to i-2-3-VM_2.vmdk
[root@host148 i-2-3-VM]# ls -l
total 19072
-rw-------. 1 root root 3221225472 Feb 13  2014 i-2-3-VM_2-flat.vmdk
-rw-------. 1 root root        519 Feb 13  2014 i-2-3-VM_2.vmdk
[root@host148 i-2-3-VM]#
c.	So when we call the migration for the second time, cloudstack looks for the file “7868703c4e8345a58d568ece092baa0e.vmdk”
and it does not find it and migration fails.
d.	Be it from netapp to non-netapp, or netapp to netapp, all the subsequent migration fails
with the following message
