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 unixan...@gmail.com 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).

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
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).
