Subject AW: Storagemigration / Primary Storages
Date Fri, 13 May 2016 08:21:35 GMT
I am not sure if the workflow is deleting a volume copied to another storage, but I know that
there is a cleanup job. Take a look at global setting:

storage.cleanup.interval

Mit freundlichen Grüßen / With kind regards,

Swen

Betreff: Re: Storagemigration / Primary Storages

Sanjeev,

thank's for your response. As you said, CS will delete the volumes from the source storage,
but I'ld expect it to be done immediately after a successful migration.
I don't think this happened correctly. Is there an easy way to track down CS-volumeid to xen-vbds
to xen-vdi to the respective LV (LVMoHBA)?
So I could check removal-tasks against the LV.

Thanks in advance!

- Stephan
