Hi once again and thank you very much for your reply. Here is another thread. I''m planning to deploy a small file server based on ZFS. I want to know if I can start with 2 RAIDs, and add more RAIDs in the future (like the gray RAID in the attached picture) to increase the space in the storage pool. I think the ZFS documentation is not very clear yet (although ZFS is very simple, I get confused) , that is why I''m asking for help in this forum. Thank you in advance and best regards.

[zfs-discuss] Is this storage model correct?
Huitzi, Yes, you are correct. You can add more raidz devices in the future as your excellent graphic suggests. A similar zpool add example is described here: http://docs.sun.com/app/docs/doc/817-2271/6mhupg6fu?a=view This new section describes what operations are supported for both raidz and mirrored configurations: http://docs.sun.com/app/docs/doc/817-2271/6mhupg6ft?a=view#gaynr If you have any suggestions for making these sections clearer, please drop me a note.

I had the same question last week decided to take a similar approach. Instead of a giant raidz of 6 disks, i created 2 raidz''s of 3 disks each. So when I want to add more storage, I just add 3 more disks. On 6/19/07, Cindy.Swearingen at sun.com <Cindy.Swearingen at sun.com> wrote:> > Huitzi, > > Yes, you are correct.

So when I want to add more storage, I just add 3 more disks.Even if you''ve created a giant 6 disk RAID-Z, apart from a formal warning requiring the -f parameter on addition, nothing would have prevented you adding a second toplevel vdev representing a 3 disk RAID-Z to the existing 6 disk one. -mg -------------- next part -------------- A non-text attachment was scrubbed...
