[lxc-users] Move container to another storage pool

[Spike]

I do the same thing altho I call it backups, moving containers from one
pool (local) to another (remote, bk server). Simplest way is to do it with
snapshots + send/reveice. because my pools are named the same I don't need
to change anything in my configuration, but in your case you'd have to
update the profiles that are referring "lxd" to refer "lxdpool" and any
other reference (can't think of another off the top of my head, other than
maybe containers you configured individually). That's it as far as I know.
Of course containers will need to be stopped during the operation or at
least restarted to pick up the new pool. So basically something like
(assuming you have a dataset called lxd.img) :

- stop containers
- zfs snapshot -r pool/lxd.img at movinglxd
- zfs send -R lxd.img at movinglxd | zfs receive pool/lxdpool
- lxd profile edit default (change reference to lxdpool)
- start containers

Hope that helps,

Spike
