snapshots contain no data.

[Ultima]

Hello James,

I'm not really sure what your expecting to see with ls, but I'll give you
some
tips and hopefully it will help.

If your interested in seeing all the snapshots, running "zfs list -t
snapshot"
will give you the list of all the snapshots, this can be piped into grep to
narrow
the list down. These snapshots can be mounted like so:
"mount -t zfs zroot at SNAPSHOT /mnt" replace SNAPSHOT with a actual
snapshot, in this case something like 2017-10-10_12.10.00--14d should work.

Hope this helps,
Richard Gallamore
