I can't be specific with my reply to the second question, as I've never done it, but do a search for "re-silvering". It is a functionality that is supposed to be there.
As to the first question, absolutely! I have upgraded my internal server twice, and both times, I was able to see the old ZFS mirror. The first time I upgraded, I forgot to do the ZFS export, so I essentially simulated a server going belly-up. In this case, you need to force the ZFS import (if you've exported first, as in the case of a server life-cycle upgrade, you don't need to force the import). If I remember correctly (I'm at work right now--bear with), the commands would be: # zpool import <pool> or # zpool import -f <pool> <pool> is the name of the ZFS pool as it was on the server before the upgrade/failure. Both times, the zpool import created the appropriate mountpoint automagically. IHTH Rainer PS I Love ZFS! :-) This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
