A basic question on failure domain

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi folks,

I have a rookie question. Does the number of the buckets chosen as the
failure domain must be equal or greater than the number of replica (or
k+m for erasure coding)?

E.g., for an erasure code profile where k=4, m=2, failure domain=rack,
does it only work when there are 6 or more racks in the CRUSH
hierarchy? Or would it continue to iterate down the tree and
eventually would work as long as there are 6 or more OSDs?

Thank you very much.

Best regards,
Cody
