Hi, Sorry if this has been raised before. Question: IS it possible to 1. Solaris 10 OS partitons to be SDS and have a single partition on that same disk (without SDS) to be ZFS slice. 2. Partition the zfs slice for many partitions and each partition to hold a zone. Idea is to create many non-global zones and each zone to be in a zfs partition. 3. Also, at a later date to increase the zfs partitions used for zones as and when required. Am I dreaming :-) Thanks Roshan

Yes.

Yes. (I guess you want to have separate zfs file systetem for each
zone)

Yes.

In that pool you can create one or more ZFS filesystems. A zone''s root directory could be installed in a ZFS filesystem, but this is not yet recommended, nor is it supported, because it is not yet possible to apply a Solaris update to a system configured like that. This will be fixed. If you don''t care about that limitation, you can put one or more zones in a ZFS fs. The best method seems to be one zone per ZFS fs. I think that''s what you were asking about. That model allows you to put a disk quota on a zone. You can accomplish that same goal with SDS (now called SVM) and soft partitions, but you wouldn''t get all of the ZFS magic. :-)> 3.

Hi Jeff & Robert, Thanks for the reply. Your interpretation is correct and the answer spot on. This is going to be at a VIP clients QA/production environment and first introduction to 10, zones and zfs. Anything unsupported is not allowed. Hence I may have to wait for the fix. Do you know roughly when the fixes will be available. So that I can give the cusrtomer some time related info. Thanks again.

Thanks again. RoshanUsing ZFS for a zones root is currently planned to be supported in solaris 10 update 5, but we are working on moving it up to update 4. --matt

If anyone is interested in working on (ie. contributing code for) this project, contact Lori.Alt at sun.com , she''s the engineer responsible for this feature. --matt
