Sangeetha Hariharan created CLOUDSTACK-5264:
-----------------------------------------------
Summary: Xenserver - Full Snapshots are not being created even
after snapshot.delta.max is exceeded
Key: CLOUDSTACK-5264
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-5264
Project: CloudStack
Issue Type: Bug
Security Level: Public (Anyone can view this level - this is the default.)
Components: Management Server
Affects Versions: 4.3.0
Environment: Build from 4.3
Reporter: Sangeetha Hariharan
Priority: Blocker
Fix For: 4.3.0
Snapshots are not being created even after snapshot.delta.max is exceeded.
Set up - Advanced zone with 2 Xenserver 6.2 hosts
Deploy 10 Vms in each of the hosts , so we start with 20 Vms.
We are constantly writing to the ROOT volume ( print timestamp every 1 minute).
Start concurrent snapshots for ROOT volumes for all the Vms.
Even after 16 snapshots have been created for the ROOT volumes , subsequent
snapshot is still not a FULL snapshot. They continue to be delta snapshot.
