You *can* but you *shouldn't*.
In general, and I don't recall if I have seen a "Best Practice" on
this or not, if you are using a zpool for multiple datasets for an NG
Zone you should not use the dataset that is at the root of the zpool,
but build child datasets. The issue is not necessarily ZFS figuring
out how / when to mount the dependent datasets, that works fine, it is
the interaction with both the Zones infrastructure and Live Upgrade
(if you are going to ever do any of that). I have had all sorts of odd
issues with hierarchical zfs datasets and NG Zones and LU.
The layout I have been using, and have not had any issues with Live
Upgrade or patching, is the following:
zpool mountpoint=none
zpool/zfs(zone root) mountpoint=/zones/fred/root (where fred is the zonename)
zpool/zfs(application) mountpoint=/zones/fs/fred/ and a lofs
mount into the NG Zone
zpool/zfs(data) mountpoint=/zones/fs/fred/ and a lofs mount into
the NG Zone
etc.
The above came about after many, many different configurations were
tried (and most failed). We adopted NG Zones before they were
supported by LU, and rolled out NG Zones on ZFS before that was
supported by LU. A long, hard path to where we are now.

Re: [zones-discuss] Solaris Zones on ZFS Filesystem or Dataset
Lao Tsao; It is not my intention to do a concurrent mount. Instead one system will relinquish the zone and pool gracefully and the other system will import it. Only upon a primary system failure, will the second system do a force import. (it's a form of poor man cluster).

Re: [zones-discuss] Solaris Zones on ZFS Filesystem or Dataset
Frank; Firstly, thanks very much for the pointers! Is there a way to set cachefile=none in a zpool that has already been created? I also googled the -u/-U option and thanks very much for the tip! Two questions; Firstly, can I create another filesystem (dataset) within the webpool e.g. say webpool/webdata and assigned it as a dataset to the webzone? Would that be considered a bad practice as it is a form cascading mount?

Re: [zones-discuss] Solaris Zones on ZFS Filesystem or Dataset
It should work, but keep in mind Zfs is not build for shared by two host, but with zpool controlled by host1 one can force imported to host2 resulting in corrupted zpool Sent from my iPad Hung-Sheng Tsao ( LaoTsao) Ph.D On May 2, 2011, at 1:09 AM, Steven Sim wrote: > Hello All; > > I have been asked to create a zone on a shared LUN which will enable us to > detach and attach the zone onto another system (exactly same hardware > architecture). > > So I have create a ZFS Pool and specified the zonepath to be on root > filesystem of that pool > > e.g. > > zfs create -m /zones/webzone webpool > > The above creates a ZFS pool called "webpool" and mounts to /zones/webzone. > > I have then in zonecfg specified the following > > zonecfg:webzone> # zonecfg -z webzone > > webzone: No such zone configured > > Use 'create' to begin configuring a new zone. > > zonecfg:webzone> create > > zonecfg:webzone> set zonepath=/zones/webpool > > zonecfg:webzone> set ip-type=exclusive > . > . > . > > Upon a need to detach, I will shutdown the zone and detach as follows .. > > # zoneadm -z appzone detach > > And then deport the ZFS Pool webpool > > #zpool deport webpool > > On the other system, I would then > > #zpool import webpool > > And start the Zone (assuming of course the zone XML file has already been > imported and created on the 2nd node). > > Is the above the best way to do things? > > Warmest Regards > Steven Sim > ___ > zones-discuss mailing list > zones-discuss@opensolaris.org ___ zones-discuss mailing list zones-discuss@opensolaris.org
[zones-discuss] Solaris Zones on ZFS Filesystem or Dataset
Hello All; I have been asked to create a zone on a shared LUN which will enable us to detach and attach the zone onto another system (exactly same hardware architecture). So I have create a ZFS Pool and specified the zonepath to be on root filesystem of that pool e.g. zfs create -m /zones/webzone webpool The above creates a ZFS pool called "webpool" and mounts to /zones/webzone. I have then in zonecfg specified the following zonecfg:webzone> # zonecfg -z webzone webzone: No such zone configured Use 'create' to begin configuring a new zone. zonecfg:webzone> create zonecfg:webzone> set zonepath=/zones/webpool zonecfg:webzone> set ip-type=exclusive . . . Upon a need to detach, I will shutdown the zone and detach as follows .. # zoneadm -z appzone detach And then deport the ZFS Pool webpool #zpool deport webpool On the other system, I would then #zpool import webpool And start the Zone (assuming of course the zone XML file has already been imported and created on the 2nd node). Is the above the best way to do things? Warmest Regards Steven Sim ___ zones-discuss mailing list zones-discuss@opensolaris.org
