Did you see my other thread on this specific topic? You can't backup
the root pool using zfs send -R | zfs recv.
Nope, somehow missed the import of that.
I'm only trying to back up the rpool/export/home portion of the root
pool;
is that still impossible?
Because so far as I can tell, *that* part is working; it's adding a
second
fs that I'm having trouble with.
In the example I posted, this bit WORKED in one case:
# zfs create bup-ruin/fsfs/rpool
# zfs send -R rpool/export/h...@bup-20090216-044512utc | zfs recv -d
bup-ruin/fsfs/rpool
I'll find that other thread and check up; is it a consistent failure or
intermittent, though?
Intermittent? That would indicate some type of transient problem, not
"can't".
I was asking because if the problem you were describing was consistent
then it's NOT my problem.
Your example worked because you are "only" replicating a filesystem
within the root pool. This works because after setting the altroot
the new (replicated) filesystem mounts in a different location than
the original.
That's all I need to do; what I need to back up is the user home
directories.
Ah. Sorry to introduce any confusion, then. I only mentioned it because
in your introductory text you said you needed to backup the root pool and
didn't say "filesystem within". I'm pretty sure it doesn't matter what
pool a filesystem is in, so your mention of the root pool threw me. In
fact AFAICT the problem with the root pool is not that it's some magic
pool called the root pool, it's that the root filesystem mounts on '/'.
If you had some other filesystem/pool with the mountpoint set to '/',
you'd have the same problem.
