The circus trick can be handled via a user-contributed utility. In fact, people can compete with their various repair utilities. There are only 1048576 1-bit permuations to try, and then the various two-bit permutations can be tried. > I don't think it's a good idea for us to assume that it's OK to 'leave out' > potential goodness for the masses that want to use ZFS in non-enterprise > environments like laptops / home PC's, or use commodity components in > conjunction with the Big Stuff... (Like white box PC's connected to an EMC or > HDS box... ) It seems that "goodness for the masses" has not been left out. The forthcoming ability to request duplicate ZFS blocks is very good news indeed. We are entering an age where the entry level SATA disk is 1TB and users have more space than they know what to do with. A little replication gives these users something useful to do with their new disk while avoiding the need for unreliable "circus tricks" to recover data. ZFS goes far beyond MS-DOS's "recover" command (which should have been called "destroy").
