Changing device-class using crushtool

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

 



Hi,

Is there a way to easily modify the device-class of devices on a offline CRUSHMap?

I know I can decompile the CRUSHMap and do it, but that's a lot of work in a large environment.

In larger environments I'm a fan of downloading the CRUSHMap, modifying it to my needs, testing it and injecting it at once into the cluster.

crushtool can do a lot, you can also run tests using device classes, but there doesn't seem to be a way to modify the device-class using crushtool, is that correct?

Wido
