I would like to know if I can create ZFS file system without ZFS storage pool. Also I would like to know if I can create ZFS pool/ZFS pool on Veritas Volume. -------------- next part -------------- An HTML attachment was scrubbed...

A ZFS filesystem without a zpool doesn''t make much sense. Unless I''m badly mistaken, you have to have the pool to get the filesystem. As far as using a Veritas volume for the zpools, that is easily done. We do that where I work for almost all of our ZFS filesystems as a way to facilitate cluster failover of the filesystems and ensure that the zpool can''t be imported on two nodes simultaneously. You just specify the VxVM volumes as the block devices when you configure the zpool. Of course, you have to import the releveant disk group before you can import the zpool.

You can make zpools from files, sparse files, physical devices, remote devices, in memory ... basically any type of storage you can communicate with. You create the zpool, and the zfs filesystem optionally comes along with it. All the magic is done in the pool - snapshots, dedup, etc. The only reason you would want a zfs filesystem is because it''s specifically designed to leverage the magic of a zpool natively. If it were possible to create a zfs filesystem without a zpool, you might as well just use ufs.
