Will this be the best way do recreate the mirror with the least downtime? I can do the zfs send/receive when the system is running. I only need to do a zfs send/receive of an incremantel snapshot when the system is not using the zpool (I need to disable services like mail and db which use zpool for storage). Then I need to rename the zpools and attach the new zpool and can bring back the services online. > > > -- > > This message posted from opensolaris.org > > _______________________________________________ > > zfs-discuss mailing list > > zfs-discuss@opensolaris.org > > http://mail.opensolaris.org/mailman/listinfo/zfs-discuss > > > > _______________________________________________ > zfs-discuss mailing list > zfs-discuss@opensolaris.org > http://mail.opensolaris.org/mailman/listinfo/zfs-discuss > _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
