Sure but it might be tedious depending on the complexity and what you want to create. > 2. Such "zpool config" tool may not be very usable for DR environment. > Why ?

I'm with you on the multipathing bit but that can easily be sed/grep/awked to something different. However, I still think the ability to dump the current config is beneficial. zpool history shows you what was done. I wouldn't want to go through every command to see what the current status is. Also history only tells me what someone typed. It doesn't tell me what other changes may have occurred. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
