The only time that I would create multiple storage pools for zones is if I intend to migrate them to other hosts independently. That is, at time t1 I have zones z1 and z2 on host h1. I think that at some time in the future I would like to move z2 to host h2 while leaving z1 on h1. Since you only have one LUN, you are not able to move the zones independently via reassigning a LUN to another host. That is, it is impossible to split the LUN and unsafe to share the LUN to multiple hosts. In your situation, I would create one pool and put both zones on it. When you decide you need more zones, put them in it too. As an aside, I rarely find the idea that I have X amount of space and Y things to put into it, so I will give each thing X/Y space. This is because it is quite likely that someone will do the operation Y++ and there are very few storage technologies that allow you to shrink the amount of space allocated to each item. -- Mike Gerdts http://mgerdts.blogspot.com/ _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
