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.

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.

[zfs-discuss] pool as root of zone
Hi, I'm Hank and I'm recovering from a crash attempting to make a zfs pool the root/mountpoint of a zone install. I want to make the zone appear as a completely configurable zfs file system to the root user of the zone. Apparently that is not exactly the way things work. Any thoughts otherwise? o Do zfs resources (datasets) need to be a separate item from the mountpoint of the zone? o Is there any problem with making a pool the mountpoint of a zone? Thanks. -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
