Subject Quicker volume migrate procedure
Date Thu, 26 Oct 2017 08:20:50 GMT
Hi all,
we have a Cloustack 4.5 on ubuntu with kvm hiperviser and NFS primary 
and secondary storage (three primary and one secondary).

We plan to dismiss the first primary storage and migrate all vm running 
on it to one of other.

When I migrate a VM (after stopping it) I noticed that the volume is 
moved in two phases, first it is copied to the Secondary and then to the 
target Primary (can you suggest where I can find documentation about 
these under the hood mechanisms?).

Are there any faster migration procedures?

I thought I could do a direct rsync of volume file from source PS to 
destination PS, stop VM, re-synchronize (differential) the file, modify 
the VM volume storage referenceon the database and restart the VM.
