Well, this is clearly a problem. I've seen it before
(there are some bugs in LU that can leave the root
dataset of a BE in this state), but I've always seen the
system boot anyway because the zfs_mountroot
code in the kernel appeared to ignore the value
of the moutnpoint property and just mounted the
dataset at "/" anyway.
Since I don't fully understand the problem, I can't
be sure this will work, but I'm pretty sure it won't
hurt: try setting the mountpoint of the dataset to "/":
zfs set mountpoint=/ rpool/ROOT/snv99
I do mean "/", not "/a". After executing the command,
the mountpoint shown with `zfs list` should be "/a"
(in the zfs list output, the current alternate root for
the pool is prepended to the persistent mount point
of the datasets to show the effective mount point).
Then reboot and see if your problem is solved. If not,
we'll dig deeper with kmdb into what's happening.
