[GSOC 2015] Enabling snapshots to be taken on primary storage for the
ESXi hypervisor using managed storage
Hi everyone,
I am Seif Eddine Jemli, a final year student in a french computer science
engineering college (ENSEIRB-MATMECA).
For GSOC 2015, I'm interested in looking at the JIRA Ticket
*CLOUDSTACK-8341* : *Enabling snapshots to be taken on primary storage for
the ESXi hypervisor using managed storage*
https://issues.apache.org/jira/browse/CLOUDSTACK-8341
My full proposal can be found on Google Melange at:
http://www.google-melange.com/gsoc/proposal/public/google/gsoc2015/sjemli/5717271485874176
I am relying on your advices and suggestions!
Regards,
Seif

I wonder, Ilya, if you are referring to VM snaps? Seif and I are referring
to volume snaps (perhaps we should clarify that in Seif's proposal).

Also, Ilya, this is for managed storage.
Manage storage requires a plug-in that can dynamically create and delete
volumes on its backend storage system.
Usually you do this when you want each virtual disk to be on its own
datastore. This would be done for quality-of-service purposes.

Hi Ilya,
Basically we want to take snapshots on the SAN that is supporting primary
storage.
We could then use those snapshots when the time comes to create CloudStack
volumes and templates.
Can you tell me more about the current behavior of snapshots for ESXi,
Ilya? What release was the behavior changed in and how does it actually
work as of that release?
Last I understood, when you initiate a snapshot from CS using ESXi, a
hypervisor
snapshot is taken and it gets copied to secondary storage.
Thanks,
Mike

Mike/Seif,
The snapshot behavior for VmWare vSphere has changed a while ago.
CloudStack now uses native VmWare snapshot ability and longer puts it on
Secondary Store.
So reading this, sort of puzzled me. Maybe explain a work flow as to
before and after scenario.
