Tamas,
are you actually doing this? any gotchas?
Yes, I do, but with LXC.
I'm trying to set up exactly the same, have a live node and a backup
node, both running zfs. I have the same containers, with the same mac,
at destination, however I'm unclear that just by copying over the
rootfs dataset from zfs it will be enough to make it work.
Has anybody done this before? I think somebody (maybe Fajar) in the
past also mentioned keeping /var/lib/lxd on zfs and replicating that
too which makes a lot of sense.
It'd be good if we could collect a sort of best practice document from
people with actual experience that do this regularly and list out all
the steps and requirements.
With LXD there is also a database which has to be somehow updated.
It's probably can be done with 'lxd import'.
I have never tested the full pipeline (replicate, stop on source,
import on dest., start on dest.), if there is anything I missed.
Cheers,
tamas
