<div class="moz-cite-prefix">Hi Arnold,<br>
<br>
Thanks for that input.<br>
<br>
In your proposal, the old secondary will still be attempting to
connect to the primary as it isn't taken down. Is that likely to
cause any issues or will the primary just not accept the
connection as its peer IP doesn't match the expected one?<br>
<br>
I like your general approach though. It begs another question:<br>
<br>
If we snapshot a copy of the secondary over to the new node before
your step (5), will the sync process just copy the data between
the time the snapshot was taken and step (5) or would it still
require a full re-sync (hence having gained nothing)? I ask
because the primary will have successfully written more data to
the old secondary than is consistent on the new secondary - I'm
wondering if that causes a problem confusing the blocks of data to
be synced from the primary (depending on the internal structure of
the metadata with which I'm unfamiliar).<br>
<br>
I'd give this a try myself in a lab, but unfortunately don't have
sufficient hardware spare at the moment. Hoping someone with
protocol / "inner workings" experience will know the theoretical
answers to save some time.<br>
<br>
Thanks,<br>
Charles.<br>
