Re: [zfs-discuss] pool as root of zone
Thanks again for comments, I want to clear this up with a few notes: o In OSOL 2009-06, zones MUST be installed in a zfs filesystem. o This is different than any dataset specified, which is like adding an fs. And of course if you specify as a dataset the same zfs pool that you installed into, the system will boot into single user mode waiting for the local filesystem service to clear with an error something like No files expected in pool Anyway, despite my operator error, I am happy to be running under 2009-06 where I can put the zone in its own zfs fs. As mentioned elsewhere, the zone path is not hidden so users can have some idea what other zones are running on your system.

My zones are created off rpool/zones.

Yes, they do. A zone's dataset is a ZFS filesystem which is owned' by the zone. Once a filesystem is zoned, it is only visible to the zone. But it seems the zone itself cannot exist in its own zfs filesystem. o Is there any problem with making a pool the mountpoint of a zone? What exactly do you want to do (and why)? Create a pool per zone? What I hoped to do, the way I thought this worked, is that you can create a zsf file system, with a size limit, make it the mountpoint of a zone, then the zone has all control to do what it wishes. So, I made the dataset equal to the mountpoint. This was actually allowed and I was able to install and boot the zone. When I rebooted the system, however, it came up in single user mode complaining that the (now) zoned zfs filesystem had files in it. The server is a long ways from home so I don't want to repeat that. OK, thanks everyone, I think I understand now that I can give a zone a zfs filesystem in a way similar to other file system resources, and that I can mount a zone into a zfs file system created in the global zone.
