2007-07-05 Thread Echo B
New on the list, so pardon if I am asking something thats been asked man y many times. Is there any plan to make it such that you can add a disk to an already established raid-z and grow that raid-z by the size of the disk? I know you can expand the zpool in this way - but that doesn't allow the ex

This is a great idea. I'd like to add a couple of suggestions: It might be interesting to focus on compression algorithms which are optimized for particular workloads and data types, an Oracle database for example. It might be worthwhile to have some sort of adaptive compression whereby ZFS could

Bellow, follows a proposal for a new opensolaris project.

Thanks, Darren. I've taken the liberty of reordering my follow-up for clarity. Just to be clear, I'm not critiquing ZFS, just trying to learn it by pushing at some of the corner cases of filesystem-system interactions. I'm trying to figure out the implications of various ZFS features when us
