It is the cherry on the cake of a RAID5 that is grown from 4 to 7 members. > Does this sound like it should work? "Do you feel lucky?" seems appropriate here. This is a classic example of what I call a "syntactic" approach to configuration: if the configuration is syntactically valid (concats of 12+1 RAID5s, ...) then fine. The idea of growing 3 times a 4+1 RAID5 into a 7+1 RAID5 three of whose members are 1+1 RAID0s (thus 1 drive of redundancy for 10 drives of data) is indeed syntactically valid as well as exceedingly clever; whether it is wise, especially with no backups, depends on how lucky one feels. Feeling very lucky like so many people on this list?
