-------------------------------------------
Summary: VM Snapshot inconsistent size
Key: CLOUDSTACK-6224
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-6224
Project: CloudStack
Issue Type: Bug
Security Level: Public (Anyone can view this level - this is the default.)
Components: Hypervisor Controller, Management Server
Affects Versions: 4.2.1
Environment: Cloudstack 4.2.1
XenServer 6.2
Vcenter 5.5 ESXi
Reporter: Artjoms Petrovs
During the creation of VM Snapshot [VMware], resulting size is written in table
„volumes”, column vm_snapshot_chain_size. It seems that size of a VM Snapshot
is calculated manually via the method getVMSnapshotChainSize(..) and it gives
overexpected result ( hundreds of terabytes ) and is much larger than the
filesize, that we can see in VMware itself. By calculating the vmdk and vmsn
file sizes manually. Xen VM snapshots [disks only] give similar results. For me
it seems that either the method works incorrectly, either it loops between some
simlinks.
