Hello,
What I am trying to accomplish is keep a vm on one host (a) in sync with
another vm on host (b). They are both using local storage for the SR, which led
me to investigate SXM. But it looks like it does just a little more then I want.
From the Storage XenMotion wiki page:
Each of a VM’s disks are snapshotted, and from the point of the
snapshot onwards, all of the disk’s writes are synchronously mirrored to the
destination storage repository. In the background, the snapshotted disk is
copied to the destination location. Once a snapshot has finished copying, the
next disk to be migrated is snapshot/mirrored.
What I am hoping to do is everything except the last step (the actual
migration).
Is it possible to pass a flag (maybe undocumented) that could accomplish this?
Or does someone know the list of commands that may accomplish this.
The sync does not necessarily have to be synchronous for my situation, so maybe
run a sync as a cron job but when a sync happens I only want the deltas copied
(not a full snapshot).
Thanks in advance.
